FIELD OF THE INVENTION

The present invention relates to micropeptides (peptides encoded by microRNAs or “miPEPs”) and use thereof for modulating gene expression.

BACKGROUND OF THE INVENTION

The microRNAs (miRNAs) are small non-coding RNAs, about 21 nucleotides in length after maturation, which control expression of target genes at the post-transcriptional level, by degrading the target mRNA or by inhibiting its translation. The miRNAs occur in plants and animals.

The target genes are often key genes in developmental processes. For example they encode transcription factors or proteins of the proteasome.

The regulation of expression of the miRNAs is very poorly understood, but it is known in particular that the latter involves, like most coding genes, an RNA polymerase II: this enzyme produces a primary transcript, called “pri-miRNA”, which is then matured by a protein complex in particular containing the Dicer type enzymes. This maturation leads firstly to the formation of a precursor of miRNA called “pre-miRNA”, having a stem-loop secondary structure containing the miRNA and its complementary sequence miRNA*. Then the precursor is matured, which leads to formation of a shorter double-stranded RNA containing the miRNA and the miRNA*. The miRNA is then manipulated by the RISC complex, which cleaves the mRNA of the target gene or inhibits its translation.

Moreover, it has been shown that the presence of introns in the primary transcript of the microRNA increases the expression of the mature microRNA (Schwab et al., EMBO Rep., 14(7): 615-21, 2013). However, owing to experimental difficulties, the primary transcripts of microRNAs, or pri-miRNAs, have received very little study.

About 50% of eukaryotic genes have small open reading frames within their 5′UTR region (5′ UnTranslated Region) upstream of the coding sequence. These small open reading frames (or “uORFs” for upstream ORFs) may perform a role of translation regulator, mainly in cis, by modulating the fixation and the rate of the ribosomes on the mRNA, but also in trans by an as yet unknown mechanism, by means of peptides encoded by said uORFs (Combier et al., Gene Dev, 22: 1549-1559, 2008). By definition, the uORFS are present upstream of coding genes.

Recently, small ORFs have also been discovered in long intergenic non-coding RNAs (lincRNAs), the putative function of which, if it exists, is not known (Ingolia et al., Cell, 147(4): 789-802, 2011; Guttman & Rinn, Nature, 482(7385): 339-46, 2012).

However, no example has yet been reported concerning the existence of ORFs encoding peptides within non-coding microRNAs. Until now, the microRNAs, and by extension their primary transcript, have always been regarded, based on their particular mode of action, as non-coding regulatory RNAs that do not produce any peptide.

SUMMARY OF THE INVENTION

One of the aspects of the invention is to propose peptides capable of modulating the expression of microRNAs.

Another aspect of the invention is to propose a means for modulating the expression of one or more target genes of a microRNA.

The present invention offers the advantage of allowing easier and more effective control of the expression of genes targeted by the microRNAs, through a means other than the microRNA.

The invention thus relates to a process for detecting and identifying a micropeptide (miPEP) encoded by a nucleotide sequence contained in the sequence of the primary transcript of a microRNA, comprising:

    • a) a step of detecting an open reading frame from 12 to 303 nucleotides in length contained in the sequence of the primary transcript of said microRNA, then
    • b) a step of comparison between:
      • the accumulation of said microRNA in a specified eukaryotic cell expressing said microRNA,
      •  in the presence of a peptide encoded by a nucleotide sequence that is identical or degenerate relative to that of said open reading frame, said peptide being present in the cell independently of transcription of the primary transcript of said microRNA, and
      • the accumulation of said microRNA in a eukaryotic cell of the same type as the aforesaid specified eukaryotic cell expressing said microRNA,
      •  in the absence of said peptide,
        in which a modulation of the accumulation of said microRNA in the presence of said peptide relative to the accumulation of said microRNA in the absence of said peptide indicates the existence of a micropeptide encoded by said open reading frame.

The invention relates in particular to a process for detecting and identifying a micropeptide (miPEP) encoded by a nucleotide sequence contained in the sequence of the primary transcript of a microRNA,

comprising:

    • a) a step of detecting an open reading frame from 15 to 303 nucleotides in length contained in the sequence of the primary transcript of said microRNA, then
    • b) a step of comparison between:
      • the accumulation of said microRNA in a specified eukaryotic cell expressing said microRNA,
      •  in the presence of a peptide encoded by a nucleotide sequence that is identical or degenerate relative to that of said open reading frame, said peptide being present in the cell independently of transcription of the primary transcript of said microRNA, and
      • the accumulation of said microRNA in a eukaryotic cell of the same type as the aforesaid specified eukaryotic cell expressing said microRNA,
      •  in the absence of said peptide,
        in which a modulation of the accumulation of said microRNA in the presence of said peptide relative to the accumulation of said microRNA in the absence of said peptide indicates the existence of a micropeptide encoded by said open reading frame.

(A) The y-axis indicates the relative expression of MtmiR171b (left-hand columns), of HAM1 (middle columns) or of HAM2 (right-hand columns) in a control plant (white columns) or in a plant in which MtmiR171b is overexpressed (black columns).

The error bar corresponds to the standard error of the mean (number of individuals=10). The overexpression of MtmiPEP171b1 induces an increase in the accumulation of MtmiR171b, as well as a decrease in the expression of the HAM1 and HAM2 genes.

(B) The y-axis indicates the mean number of lateral roots observed in a control plant (white column) or in a plant in which MtmiPEP171b1 is overexpressed (black column). The error bar corresponds to the standard error of the mean (number of individuals=100). The overexpression of MtmiPEP171b1 leads to a reduction in the number of lateral roots.

(A) The y-axis indicates the relative expression of MtmiR171b (left-hand columns), of HAM1 (middle columns) or of HAM2 (right-hand columns) in a control plant (white columns) or in a plant treated by watering once daily for 5 days with MtmiPEP171b1 at 0.01 μM (light grey columns), 0.1 μM (dark grey columns) or 1 μM (black columns). The error bar corresponds to the standard error of the mean (number of individuals=10). Application of MtmiPEP171b1 at different concentrations induces an increase in the accumulation of MtmiR171b, as well as a decrease in the expression of the HAM1 and HAM2 genes.

(B) The y-axis indicates the mean number of lateral roots observed in a control plant (white column) or in a plant treated by watering with MtmiPEP171b1 at 0.1 μM once daily for 5 days (black column). The error bar corresponds to the standard error of the mean (number of individuals=100). Application of MtmiPEP171b1 at 0.1 μM leads to a reduction in the number of lateral roots.

(C) The y-axis indicates the relative expression of MtmiR171b (left-hand columns), of HAM1 (middle columns) or of HAM2 (right-hand columns) in a control plant (white columns) or in a plant treated by watering once daily for 5 days with MtmiPEP171b1 at 0.01 μM (grey columns), 0.1 μM (dark grey columns) or 1 μM (black columns) or with 0.01 μM of a mixed peptide (light grey columns) the amino acid composition of which is identical to miPEP171b but the sequence of which is different. The error bar corresponds to the standard error of the mean (number of individuals=10).

FIG. 4. Effects of MtmiPEP171b1 on the expression of pre-MtmiR171b (A) and of MtmiR171b (B) in M. truncatula.

The y-axis indicates the relative expression of the precursors of the different forms of the microRNA in control plants (left-hand column) or in plants treated by watering once daily for 5 days with MtmiPEP171b1 at 0.01 μM, 0.1 μM or 1 μM (right-hand columns). The error bar corresponds to the standard error of the mean (number of individuals=200). Application of MtmiPEP171b1 at different concentrations leads to an increase in the accumulation of pre-MtmiR171b (A) and of MtmiR171b (B).

FIG. 5. Effects of overexpression of MtmiPEP171b1 (A) and effects of MtmiPEP171b1 (B) on the expression of different precursors of microRNAs in M. truncatula.

The y-axis indicates the ratio of the expression of the precursors of microRNAs in plants overexpressing MtmiPEP171b1 to the expression of these same precursors in control roots (A), or the ratio of the expression of the precursors of microRNAs in plants treated with MtmiPEP171b1 (0.1 μM) to the expression of these same precursors in control roots (B). The different precursors of microRNAs tested are indicated from left to right on the x-axis, namely pre-MtmiR171b (SEQ ID NO: 246), pre-MtmiR169 (SEQ ID NO: 359), pre-MtmiR169a (SEQ ID NO: 360), pre-MtmiR171a (SEQ ID NO: 361), pre-MtmiR171 h (SEQ ID NO: 362), pre-MtmiR393a (SEQ ID NO: 363), pre-MtmiR393b (SEQ ID NO: 364), pre-MtmiR396a (SEQ ID NO: 365) and pre-MtmiR396b (SEQ ID NO: 366). The error bar corresponds to the standard error of the mean (number of individuals=10). It is noted that MtmiPEP171b1 only leads to an effect on the accumulation of MtmiR171b and not on the other miRNAs.

FIG. 6. Effects of translation of MtmiPEP171b1 on the expression of MtmiR171b demonstrated in the model plant Nicotiana benthamiana. The y-axis indicates the relative expression of MtmiR171b in tobacco plants transformed in order to express pri-MtmiR171b (white column) or a mutated pri-MtmiR171b in which the codon ATG has been replaced with ATT (black column). The mutated pri-MtmiR171b is therefore incapable of producing MtmiPEP171b1. The error bar corresponds to the standard error of the mean (number of individuals=30). It is noted that the absence of translation of MtmiPEP171b1 leads to a marked decrease in the accumulation of miR171b.

FIG. 7. Effects of overexpression of MtmiPEP171b1 on the expression of pre-MtmiR171b demonstrated in the model plant Nicotiana benthamiana.

The y-axis indicates the relative expression of pre-MtmiR171b in tobacco plants that have been transformed in order to express MtmiR171b (left-hand column), MtmiR171b and MtmiPEP171b1 (middle column), or MtmiR171b and a mutated version of MtmiORF171b in which the start codon ATG has been replaced with ATT (right-hand column). The error bar corresponds to the standard error of the mean (number of individuals=30). It is noted that the expression of MtmiPEP171b1 increases the expression of MtmiR171b, and this effect is dependent on the translation of MtmiORF171b to MtmiPEP171b1.

FIG. 8. Effects of MtmiPEP171b1 on the expression of pre-MtmiR171b demonstrated in the model plant Nicotiana benthamiana.

The y-axis indicates the relative expression of MtmiR171b in tobacco plants transformed in order to express MtmiR171b onto which MtmiPEP171b1 has been sprayed (0.1 μM) twice, 12 h and then 30 min before sampling (right-hand column) or not (left-hand column). The error bar corresponds to the standard error of the mean (number of individuals=6). The peptide MtmiPEP171b1 applied by spraying induces an increase in the accumulation of MtmiR171b.

FIG. 9. Effects of MtmiPEP171b1 on the expression of pri-miR171b (A), pre-MtmiR171b (B) and MtmiR171b (C) demonstrated in the model plant Nicotiana benthamiana.

The y-axis indicates the relative expression of the precursors of the different forms of the microRNA in tobacco plants modified in order to express MtmiR171b (left-hand column) or modified in order to express MtmiR171b and overexpress MtmiPEP171b1 (right-hand columns, FIG. 9A) or treated with 0.1 μM of miPEP171b1 (FIGS. 9B and C). The error bar corresponds to the standard error of the mean (number of individuals=30). The overexpression of MtmiPEP171b1 or application of miPEP171b1 increases the accumulation of pri-MtmiR171b (A), pre-MtmiR171b (B) and MtmiR171b (C).

FIG. 10. Localization of MtmiPEP171b1 in tobacco leaf cells that have been modified in order to express MtmiPEP171b1.

The photographs show tobacco leaf cells modified in order to express the protein GFP alone (left panel) or the protein GFP fused to MtmiPEP171b1 (right panel). These observations indicate that MtmiPEP171b1 is localized in small nuclear bodies.

FIG. 11. Effects of the expression of AtmiPEP165a (identified in Arabidopsis thaliana) on the expression of AtmiR165a (A), and of the expression of AtmiPEP319a2 (identified in Arabidopsis thaliana) on AtmiR319a (B), demonstrated in the model plant of tobacco.

(A) The y-axis indicates the relative expression of AtmiR165a in tobacco plants modified in order to express AtmiR165a (left-hand column) or to express AtmiR165a and AtmiPEP165a (right-hand column).

(B) The y-axis indicates the relative expression of AtmiR319a in tobacco plants modified in order to express AtmiR319a (left-hand column) or in order to express AtmiR319a and AtmiPEP319a (right-hand column).

The error bar corresponds to the standard error of the mean (number of individuals=30).

In both cases, it is noted that the expression of miORF, and therefore the production of miPEP, leads to an increase in the accumulation of pre-miRNA.

FIG. 12. Effects of treatment with AtmiPEP165a on root growth in Arabidopsis thaliana.

The photograph shows two plants of the same age: a control plant (plant on the left) and a plant treated with AtmiPEP165a (plant on the right). The treatment with AtmiPEP165a leads to a phenotype with greatly accelerated root growth in Arabidopsis thaliana. The graph shows the expression of pre-miR165 in response to treatment with increasing doses of AtmiPEP165a.

FIG. 13. Conservation of the sequence of miPEP8 identified in Drosophila.

The sequences of miPEP8 (SEQ ID NO: 104) were deduced from the sequences of miORF8 (SEQ ID NO: 208) of 12 different Drosophila species and were aligned. A histogram shows the conservation of each amino acid between the sequences of miORF8 in the 12 species analysed.

FIG. 14. Evolution of the mass (kDa) and isoelectric point (pI) of miPEP8 in the Drosophila species.

The y-axis on the left indicates the size of the miPEP8 (in kD). The y-axis on the right indicates the isoelectric point of the miPEP. The x-axis indicates the origin of the miPEP, i.e. the Drosophila species. It is noted that despite a significant change in their size (by more than a factor of 3), the charge of the miPEPs is still very basic (>9.8) in the 12 species studied.

FIG. 15. Effect of the addition of sequences on the function of miPEP.

The tobacco leaves were transformed in order to overexpress miPEP171b. These graphs show that the addition of sequences (tag His, HA or GFP) does not alter the function of miPEP. The y-axis indicates the relative expression of pre-MtmiR171b in tobacco plants that have been transformed in order to express MtmiR171b (left-hand column), MtmiR171b and MtmiPEP171b1 with or without addition of protein tags (right-hand columns). The error bar corresponds to the standard error of the mean (number of individuals=6). It is noted that the expression of MtmiPEP171b1 increases the expression of MtmiR171b, and this effect is independent of the presence of tags.

FIG. 16. Expression of MtmiPEP171b1 in the root system of Medicago truncatula.

The roots of Medicago truncatula were transformed in order to express fusions between GUS protein (in blue) and the promoter of miR17b (A, E), the ATG of miPEP171b1 (B, F), whole miPEP171b1 (C, G) or ATG2 (second ATG located on the precursor, after miPEP) (D, H). It is clear that there is expression of miRNA in the root tips (A) as well as the lateral roots (E). The transcriptional (B, F) and translational (C, G) fusions show an expression of miPEP171b in the same tissues, whereas the next ATG is not active (D, H).

FIG. 17. Expression of DmmiPEP8 in cells of Drosophila melanogaster

The cells of Drosophila melanogaster were transfected in order to overexpress DmmiPEP8 (OE miPEP8) or miPEP8 of which the translation start codons have been mutated (OE miPEP8 mut). The y-axis indicates the relative expression of Pre-miR8. The error bar corresponds to the standard error of the mean (number of independent experiments=6). It is noted that the expression of DmmiPEP8 increases the expression of DmmiR8, and this effect is linked to the translation of the mRNA.

FIG. 18. Impact of DmmiPEP8 on accumulation of DmmiR8 in cells of D. melanogaster

The cells of Drosophila melanogaster were transfected in order to overexpress wild-type DmmiR8 (OE miR8) or DmmiR8 the translation start codons of which have been mutated (OE miR8 miPEP8 mut). The y-axis indicates the relative expression of Pre-miR8. The error bar corresponds to the standard error of the mean (number of independent experiments=2). It is noted that the presence of DmmiPEP8 increases the expression of DmmiR8.

FIG. 19. Impact of HsmiPEP155 on accumulation of HsmiR155 in cells of Homo sapiens

HeLa cells of Homo sapiens had been transfected in order to overexpress HsmiPEP155 (OE miPEP155). The y-axis indicates the relative expression of Pre-miR155. The error bar corresponds to the standard error of the mean (number of independent experiments=2). It is noted that the expression of HsmiPEP155 increases the expression of HsmiR155.

FIG. 20. Effects of translation of MtmiPEP171b1 on the expression of MtmiR171b demonstrated in the model plant Nicotiana benthamiana.

The y-axis indicates the relative expression of MtmiR171b in tobacco plants transformed in order to express pri-miR171b (left-hand column), a pri-miR171b in which the miORF171b has been deleted (middle column) or a mutated pri-miR171b in which the codon ATG has been replaced with ATT (right-hand column). The mutated pri-miR171b is therefore incapable of producing miPEP171b1. The error bar corresponds to the standard error of the mean (number of individuals=30). It is noted that the absence of translation of miPEP171b1 leads to a marked decrease in the accumulation of miR171b.

FIG. 21. Effects of overexpression of MtmiPEP171b1 on the expression of MtmiR171b demonstrated in the model plant Nicotiana benthamiana.

The y-axis indicates the relative expression of MtmiR171b in tobacco plants that had been transformed with a vector allowing the expression of miPEP171b and either a second empty vector (white column), or a vector allowing the expression of mtmiPEP171b (left black column), or a vector in which the codon ATG of the ORF encoding mtmiPEP171b has been replaced with ATT (middle black column), or a vector in which the nucleotide sequence of the ORF has been mutated without modifying the amino acid sequence of the translated peptide (miPEP encoded by a degenerate ORF) (right black column). The error bar corresponds to the standard error of the mean (number of individuals=30). It is noted that the expression of MtmiPEP171b1 increases the expression of MtmiR171b, and this effect is dependent on the translation of MtmiORF171b to MtmiPEP171b1.

FIG. 22. Effects of AtmiPEP165a on accumulation of AtmiR165a and of its target genes (PHA VOL UTA: PHV, PHABOL USA: PHB and REVOLUTA: REV).

The y-axis indicates the relative expression of AtmiR165a, PHV, PHB and REV in roots of Arabidopsis thaliana treated with water (control) or different concentrations of AtmiPEP165a (0.01 μM, 0.1 μM, 1 μM or 10 μM). The error bar corresponds to the standard error of the mean (number of individuals=10).

The treatment of plants with higher and higher concentrations of AtmiPEP165a demonstrates a dose-dependent effect of the accumulation of AtmiR165a and the negative regulation of its target genes as a function of the quantity of AtmiPEP165a.

FIG. 23. Effects of treatment with AtmiPEP164a on the expression of AtmiR164a in A. thaliana.

The photographs show the results of a Northern blot analysis of the accumulation of AtmiR164a in roots treated with water (control, photograph on left) or with 0.1 μM of a synthetic peptide, having a sequence identical to that of AtmiPEP164a, dissolved in water (0.1 μM miPEP164a). The RNA U6 is used as loading control making it possible to quantify the quantity of AtmiR164a.

This experiment was repeated 4 times independently and led to similar results.

Treatment of shoots of A. thaliana with 0.1 μM of miPEP164a leads to an increase in the accumulation of miR164a.

FIG. 24. Effects of treatment with AtmiPEP164a on the growth of Arabidopsis thaliana.

The photographs show two plants (top views and side views) after 3 weeks of growth: a control plant watered with water (A), and a plant watered with a composition of 0.1 μM of synthetic peptide corresponding to AtmiPEP164a (B). Watering plants of Arabidopsis thaliana with AtmiPEP164a increases plant growth significantly.

FIG. 25. Effects of treatment with AtmiPEP165a on the expression of AtmiR165a in A. thaliana.

The photographs show the results of a Northern blot analysis of the accumulation of AtmiR165a in roots treated with water (control, photograph on left) or with 0.1 μM of a synthetic peptide, having a sequence identical to that of AtmiPEP165a, dissolved in water (0.1 μM miPEP165a). The RNA U6 is used as loading control making it possible to quantify the quantity of AtmiR165a.

This experiment was repeated 4 times independently and led to similar results.

Treatment of A. thaliana shoots with 0.1 μM of miPEP165a leads to an increase in the accumulation of miR165a.

FIG. 26. Effects of overexpression of AtmiPEP319a1 on the expression of AtmiR319a in A. thaliana.

The y-axis indicates the relative expression of AtmiR319a in a control plant (left-hand column) or in a plant in which AtmiPEP319a1 is overexpressed (right-hand column). The error bar corresponds to the standard error of the mean (number of individuals=10). The overexpression of AtmiPEP319a1 induces an increase in the accumulation of AtmiR319a.

FIG. 27. Effects of treatment with AtmiPEP319a on the growth of Arabidopsis thaliana.

The photographs show two plants (top views and side views) after 3 weeks of growth: a control plant watered with water (A), and a plant watered with a composition of 0.1 μM of synthetic peptide corresponding to AtmiPEP319a1 (B). Watering of the plants of Arabidopsis thaliana with AtmiPEP319a1 increases plant growth significantly.

FIG. 28. Immunolocalization.

The roots of Medicago truncatula were transformed in order to express fusions between the GUS protein (in blue) and the ATG of miPEP171b (PromiR171b-ATG1:GUS) or ATG2 (second ATG located on the precursor, after miPEP) (PromiR171b-ATG2:GUS). Labelling was also carried out with an anti-miPEP171b antibody (miPEP171b). Immunolocalization of miPEP171b in the roots of M. truncatula reveals the presence of miPEP171b in the lateral root initiation sites, showing a co-localization between the microRNA and the corresponding miPEP.

 DETAILED DESCRIPTION OF THE INVENTION

In a first step, the process for detecting and identifying a micropeptide therefore consists of detecting, on the primary transcript of a microRNA, the existence of an open reading frame potentially encoding a peptide.

For its part, the second step makes it possible to characterize said peptide, i.e. to determine whether said peptide corresponds to a peptide really produced in the cell, by searching for an effect of said peptide on the accumulation of said microRNA.

In order to demonstrate an effect of the peptide on the accumulation of the microRNA, a large quantity of peptide is introduced into a first cell expressing said microRNA. The accumulation of the microRNA in this first cell is then measured and compared with the accumulation of the microRNA in a second cell identical to the first, but not containing said peptide.

Observation of a variation of the quantities of microRNA between the cells in the presence and in the absence of the peptide thus indicates (i) that there is a peptide encoded on the primary transcript of said microRNA, (ii) that the sequence of this peptide is encoded by the open reading frame identified on the primary transcript of said microRNA, and (iii) that said peptide has an effect on the accumulation of said microRNA.

The invention is therefore based on the unexpected double observation made by the inventors that, on the one hand, there are open reading frames that are able to encode micropeptides present on the primary transcripts of microRNAs, and on the other hand that said micropeptides are capable of modulating the accumulation of said microRNAs.

In particular, the invention relates to a process for detecting and identifying a micropeptide (miPEP) encoded by a nucleotide sequence contained in the sequence of the primary transcript of a microRNA, comprising:

    • a) a step of detecting an open reading frame from 15 to 303 nucleotides in length contained in the sequence of the primary transcript of said microRNA, then
    • b) a step of comparison between:
      • the accumulation of said microRNA in a specified eukaryotic cell expressing the primary transcript of said microRNA,
      •  in the presence of a peptide encoded by a nucleotide sequence that is identical or degenerate relative to that of said open reading frame, said peptide being present in the cell independently of transcription of the primary transcript of said microRNA, and
      • the accumulation of said microRNA in a eukaryotic cell of the same type as the aforesaid specified eukaryotic cell expressing the primary transcript of said microRNA,
      •  in the absence of said peptide,
        in which a modulation of the accumulation of said microRNA in the presence of said peptide relative to the accumulation of said microRNA in the absence of said peptide indicates the existence of a micropeptide encoded by said open reading frame.

In the invention, the terms “microRNA”, “non-coding microRNA” and “miRNA” are equivalent and may be used interchangeably. They define small molecules of RNA of about 21 nucleotides, which are not translated and do not lead to a peptide or a protein. However, in this mature form, the microRNAs perform a function of regulation of certain genes via post-transcriptional mechanisms, for example by means of the RISC complex.

The primary transcript of the microRNA or “pri-miRNA” corresponds to the RNA molecule obtained directly from transcription of the DNA molecule. Generally, this primary transcript undergoes one or more post-transcriptional modifications, involving for example a particular structure of the RNA or cleavage of certain portions of the RNA by splicing phenomena, and which lead to the precursor form of the microRNA or “pre-miRNA”, then to the mature form of the microRNA or “miRNA”.

The terms “micropeptides” and “miPEPs” (microRNA encoded PEPtides) are equivalent and may be used interchangeably. They define a peptide that is encoded by an open reading frame present on the primary transcript of a microRNA, and which is capable of modulating the accumulation of said microRNA.

In view of the above definitions, it is important to distinguish on one side, the miRNA which does not encode any peptide and on the other side, the primary transcript of such a miRNA which may encode a miPEP.

This distinction derives from the teaching of the invention and is original in view of the current knowledge about miRNAs.

The micropeptides within the meaning of the present invention are not to be understood as necessarily being small peptides, as “micro” does not correspond to the size of the peptide.

Taking into account the degeneracy of the genetic code, one and the same micropeptide is or may be encoded by several nucleotide sequences. Nucleotide sequences of this kind, differing from one another by at least one nucleotide but encoding one and the same peptide, are called “degenerate sequences”.

The terms “open reading frame” or “ORF” are equivalent and may be used interchangeably. They correspond to a nucleotide sequence in a DNA or RNA molecule that may potentially encode a peptide or a protein: said open reading frame begins with a start codon (the start codon generally encoding a methionine), followed by a series of codons (each codon encoding an amino acid), and ends with a stop codon (the stop codon not being translated).

In the invention, the ORFs may be called specifically “miORFs” when they are present on the primary transcripts of microRNA.

The miORFs as defined in the particular invention may have a size from 12 to 303 nucleotides and may encode peptides from 3 to 100 amino acids.

In particular, the miORFs as defined in the invention may have a size from 15 to 303 nucleotides. As an amino acid is encoded by a codon of 3 nucleotides, the miORFs from 15 to 303 nucleotides encode miPEPS from 4 to 100 amino acids.

In particular, the miORFs have a size of:

15, 18, 21, 24, 27, 30, 33, 36, 39, 42, 45, 47, 51, 54, 57, 60, 63, 66, 69, 72, 75, 78, 81, 84, 87, 90, 93, 96, 99, 102, 105, 108, 111, 114, 117, 120, 123, 126, 129, 132, 135, 138, 141, 144, 147, 150, 153, 156, 159, 162, 165, 168, 171, 174, 177, 180, 183, 186, 189, 192, 195, 198, 201, 204, 207, 210, 213, 216, 219, 222, 225, 228, 231, 234, 237, 240, 243, 246, 249, 252, 255, 258, 261, 264, 267, 270, 273, 276, 279, 282, 285, 288, 291, 294, 297, 300 or 303 nucleotides, and encode respectively miPEPs having a size of:

In the invention, “accumulation” means the production of a molecule, such as a microRNA or a micropeptide, in the cell.

Thus, “modulation” of the accumulation of a molecule in a cell corresponds to a modification of the quantity of this molecule present in the cell.

In an embodiment, the invention relates to a process for detecting and identifying a miPEP as defined above, in which the modulation of the accumulation of said microRNA is a decrease or an increase in the accumulation of said microRNA, in particular an increase.

A “decrease in the accumulation” corresponds to a decrease in the quantity of said molecule in the cell.

Conversely, an “increase in the accumulation” corresponds to an increase in the quantity of said molecule in the cell.

In an advantageous embodiment, the invention relates to a process for detecting and identifying a miPEP as defined above, in which the modulation of the accumulation of said microRNA is an increase in the accumulation of said microRNA.

In an embodiment, the invention relates to a process for detecting and identifying a miPEP as defined above, in which the presence of said peptide in the cell results from:

    • the introduction of a nucleic acid encoding said peptide into the cell, or
    • the introduction of said peptide into the cell.

In order to characterize a miPEP, it is necessary to have a cellular model expressing a microRNA in which said peptide to be tested is present. For this, it is possible to introduce a peptide into the cell, either by bringing the cell into contact with said peptide, or by introducing a nucleic acid encoding said peptide into the cell, and this nucleic acid will then be translated into peptide within the cell.

In an embodiment, the invention relates to a process for detecting and identifying a miPEP as defined above, in which said open reading frame in step a) is contained in the 5′ or 3′ portion of said primary transcript of the microRNA, preferably in the 5′ portion.

The 5′ or 3′ portions of the primary transcript of the microRNA correspond to the terminal portions of the RNA molecule that are cleaved during maturation of the microRNA.

In an embodiment, the invention relates to a process for detecting and identifying a miPEP as defined above, in which said microRNA is present in a wild-type plant cell. In the invention, a wild-type plant cell corresponds to a plant cell that has not been genetically modified by humans.

In an embodiment, the invention relates to a process for detecting and identifying a miPEP as defined above, in which said microRNA is present in a wild-type animal cell, and in particular a wild-type human cell or a wild-type Drosophila cell.

In the process for detecting and identifying a micropeptide as defined above, after identifying an ORF that is able to encode a peptide on the primary transcript of a microRNA, it is necessary to have a cellular model having said microRNA and said peptide, so as to be able to demonstrate a possible effect of the peptide on said microRNA.

Two options are therefore conceivable:

    • the cellular model in which the miORF has been identified and that in which the effect of the peptide on the miRNA has been demonstrated are identical, or
    • the cellular model in which the miORF has been identified and that in which the effect of the peptide on the miRNA has been demonstrated are different.

In the first option, the cellular model used for observing an effect of the peptide is the same as that in which the primary transcript of said microRNA was isolated. In this cellular model, the specified eukaryotic cells contain said microRNA naturally and only the peptide

to be tested has to be introduced into these cells. In this context, said microRNA is qualified as “of endogenous origin” as it exists naturally in the cells. Nevertheless, other copies of a microRNA of endogenous origin may be added to a cell, for example by introducing a vector encoding said microRNA of endogenous origin into the cell.

In the second option, the cellular model used for observing an effect of the peptide is different from that in which the primary transcript of said microRNA was isolated. In this cellular model, the specified eukaryotic cells contain neither the microRNA, nor the peptide to be tested. These two elements must therefore be introduced into these cells. In this context, said microRNA is qualified as “of exogenous origin” as it does not exist naturally in the cells.

      •  in the absence of said peptide,
        in which a modulation of the accumulation of said microRNA in the presence of said peptide relative to the accumulation of said microRNA in the absence of said peptide indicates the existence of a microRNA the primary transcript of which contains a nucleotide sequence encoding a micropeptide.

In the invention, the expressions “of endogenous origin” and “of exogenous origin” are used for distinguishing said microRNAs and/or the genes of different species, in view of the conservation of the sequences between species.

In another aspect, the invention relates to the use of a composition as defined above, in which said composition is applied to a plant to protect it against insect pests.

In another aspect, the invention relates to the use of a peptide for promoting the growth of a plant, said peptide being introduced into the plant, said peptide having an amino acid sequence comprising or consisting of a sequence identical to that of a miPEP naturally present in said plant,

said miPEP naturally present in said plant being a peptide of 4 to 100 amino acids the sequence of which is encoded by an open reading frame located on the primary transcript of a miRNA, said miPEP being capable of modulating the accumulation of said miRNA in said plant, said miRNA regulating the expression of at least one gene involved in the development of the vegetative or reproductive parts of the plant, in particular the roots, stem, leaves or flowers.

The inventors have surprisingly found that the use of peptides the sequence of which comprises or consists of a sequence identical to that of miPEPs encoded on the primary transcripts of miRNAs makes it possible to promote the growth of the plants.

In the invention, the term “plant” refers generally to the whole or part of a plant irrespective of its stage of development (including the plant in the form of a seed or a young shoot), to one or more organs of the plant (for example the leaves, roots, stem, flowers), to one or more cells of the plant, or to a cluster of cells of the plant.

In the invention, the term “growth” refers to the development of the whole or part of a plant over time. The growth of the plant may thus be determined and quantified by monitoring developmental parameters observable for certain parts, cells or organs of the plant, such as the leaves, roots, stems or flowers.

Non-limitatively, the parameters for determining and quantifying the growth of a plant may in particular be:

    • the size, surface area, volume, mass and the number of leaves,
    • the size and number of flowers,
    • the size of the stem (or spike),
    • the length and number of roots,
    • the earliness of germination,
    • the earliness of budding,
    • the earliness of floral induction (or floral transition),
    • or also the number of cells.

In the case of leguminous plants, plant growth may also be linked to the rate of nodulation, or also to the size and number of nodules on the roots.

Moreover, in the invention, the expression “promote plant growth”, or “improve plant growth”, indicates:

    • either an acceleration of development (such as for example a larger leaf size for a plant at a given point in time relative to a reference plant),
    • or an increase in development (such as for example a larger leaf size for a plant that cannot be attained by a reference plant),
    • or an acceleration and an increase in the development of the plant.

It is important to note that the use according to the invention has the advantage of being ecological, in comparison with the chemical methods used conventionally in horticulture or in agriculture, as the miPEP is a peptide that is present naturally in the plant.

The invention also relates to the use of a miPEP introduced into a plant for promoting its growth,

said miPEP introduced being a peptide comprising, or consisting of, a sequence identical to that of a miPEP naturally present in said plant,
said miPEP naturally present is a peptide of 4 to 100 amino acids, the sequence of which is encoded by an open reading frame located at 5′ on the primary transcript of a miRNA,
said miPEP being capable of modulating the accumulation of said miRNA in said plant,
said miRNA regulating the expression of at least one gene involved in the development of the vegetative or reproductive parts of the plant, in particular the roots, stem, leaves or flowers, the sum total of the quantity of said miPEP introduced and that of said miPEP naturally present being strictly greater than the quantity of said miPEP naturally present.

In the invention, the expression “miPEP introduced” refers to a miPEP introduced into the plant artificially as opposed to the “miPEP present naturally in the plant”. The introduction of a miPEP into the plant therefore involves a technological step, which is not a natural phenomenon and corresponds neither to crossing, nor to selection.

The miPEP introduced may be either a peptide produced outside of the plant (for example an isolated and/or purified peptide, a synthetic peptide or a recombinant peptide), or a peptide produced in the plant following the non-natural introduction of a nucleic acid encoding said miPEP into said plant.

The plant into which the miPEP has not been introduced has a basal quantity of said miPEP, which corresponds to the quantity of said miPEP naturally present. The use of a miPEP comprising, or consisting of, a sequence identical to that of said miPEP leads to an increase in the total quantity of miPEP, which modulates the accumulation of the miRNA the primary transcript of which contains the sequence encoding said miPEP.

Moreover, the miPEP introduced is present in the plant and its introduction has no impact on its stability.

EXAMPLES A: Analysis of the miPEPS in Plants Example 1 Characterization in the Model Plant Medicago truncatula

a) Identification and Characterization of MtmiPEP171b1 (miPEP171b1 Identified in Medicago truncatula)

This microRNA is expressed in the meristematic region of the roots. The overexpression of this microRNA in particular leads to a reduction in the expression of the genes HAM1 (Accession No. MtGI9-TC114268) and HAM2 (Accession No. MtGI9-TC120850) (FIG. 1A), as well as to a reduction in the number of lateral roots (FIG. 1B).

The sequence of the primary transcript of MtmiR171b was determined using the RACE-PCR technique. Analysis of the sequence of the primary transcript made it possible to identify the presence of several completely unexpected small open reading frames (sORFs). These sORFs were called miORFs for “microRNA ORFs”. These miORFs potentially encode short peptides, from about 4 to 100 amino acids. No significant homology relating to these miORFS was found in the databases.

The overexpression of the first miORF, called MtmiORF171b, leads to an increase in the accumulation of MtmiR171b and a reduction in the expression of the HAM1 and HAM2 genes (see FIG. 2A), as well as to a reduction in the number of lateral roots (FIG. 2B), as was already observed in the overexpression of MtmiR171b.

In order to determine whether MtmiORF171b leads to the real production of a peptide and whether the regulatory function observed above is indeed carried by said peptide, a synthetic peptide, the sequence of which is identical to that potentially encoded by MtmiORF171b, was applied on the roots of Medicago truncatula. Application of this peptide leads to the phenotype already observed above in the overexpression of MtmiORF171b, i.e. it leads to an increase in the accumulation of MtmiR171b and a reduction in the expression of the HAM1 and HAM2 genes (see FIG. 3A), as well as a reduction in the number of lateral roots (FIG. 3B).

The results of these experiments demonstrate that MtmiORF171b encodes a peptide capable of modulating the accumulation of MtmiR171b, and the expression of the target genes of MtmiR171b: HAM1 and HAM2. Said peptide has been called MtmiPEP171b1 (“miPEP” corresponding to microRNA encoded PEPtide).

Moreover, MtPEP171b1 leads to an increase in the accumulation of MtmiR171b (FIG. 104A) and of pre-MtmiR171b (FIG. 4B).

b) Specificity of miPEP171b1

The expression of different microRNA precursors of Medicago truncatula (MtmiR171b SEQ ID NO: 319, MtmiR169 SEQ ID NO: 367, MtmiR169a SEQ ID NO: 368, MtmiR171a SEQ ID NO: 369, MtmiR171 h SEQ ID NO: 370, MtmiR393a SEQ ID NO: 371, MtmiR393b SEQ ID NO: 372, MtmiR396a SEQ ID NO: 373 and MtmiR396b SEQ ID NO: 374) was determined and compared between control plants and plants in which MtmiORF171b encoding MtmiPEP171b1 was overexpressed (FIG. 5A), or between control plants and plants grown on culture medium containing MtmiPEP171b1 (FIG. 5B).

The results obtained indicate that MtmiPEP171b1 only leads to an increase in the accumulation of MtmiR171b and not of the other miRNAs, which indicates that a miPEP only has an effect on the microRNA from which it is derived.

c) Localization of miPEP171b1

Moreover, the immunolocalization of miPEP171b1 in the roots of M. truncatula reveals the presence of miPEP171b1 in the lateral root initiation sites, showing a co-localization between the microRNA and the corresponding miPEP (FIG. 28).

Example 2 Characterization in the Model Plant of Tobacco a) Conservation of the Mechanism in Tobacco

In order to determine whether the mechanism of regulation of the microRNAs is conserved in other plant species, the regulation of MtmiR171b by MtmiPEP171b1 was tested in a different cellular model. For this, MtmiR171b and MtmiPEP171b1 were introduced into tobacco leaves.

The accumulation of MtmiR171b was measured in tobacco leaves transformed in order to express MtmiR171b of Medicago truncatula starting from wild-type pri-miRNA capable of producing MtmiPEP171b1, or starting from a mutated version of pri-miRNA incapable of producing MtmiPEP171b1 (in which the start codon ATG of MtmiORF171b has been replaced with ATT) (FIG. 6 and FIG. 20). Absence of translation of MtmiPEP171b1 leads to a marked decrease in the accumulation of MtmiR171b.

The accumulation of pre-MtmiR171b was measured in tobacco leaves transformed in order to express MtmiR171b of Medicago truncatula alone (control), or additionally expressing the wild-type MtmiORF171b of Medicago truncatula (35SmiPEP171b1 ATG), or a mutated version of MtmiORF171b in which the start codon ATG has been replaced with ATT (35SmiPEP171b1 ATT) (FIG. 7 and FIG. 21). The expression of MtmiORF171b leads to an increase in the accumulation of pre-miR171b, and this accumulation of pre-miR171b depends on the translation of MtmiORF171b to micropeptide.

Moreover, in the tobacco leaves transformed in order to express MtmiR171b of Medicago truncatula, untreated or treated by spraying with MtmiPEP171b1 (0.1 μM) for the first time 12 h before sampling and then a second time 30 minutes before sampling, it was observed that MtmiPEP171b1 may be used directly in peptide form by foliar sprayings (FIG. 8).

Moreover, it was observed in tobacco (as in Medicago truncatula) that the MtmiPEP171b1 leads to an increase in the accumulation of MtmiR171b (FIG. 9A) and of pre-MtmiR171b (FIG. 9B), but reduces the accumulation of pri-MtmiR171b (FIG. 9C).

Taken together, these results indicate that the mechanism of regulation of the microRNAs and of their target genes under the control of miPEPs is conserved between the species.

b) Intracellular Localization of MtmiPEP171b1

Tobacco leaves were transformed in order to overexpress MtmiPEP171b1 of Medicago truncatula fused with a fluorescent protein (GFP) (FIG. 10). The results obtained indicate that the miPEP is localized in small nuclear bodies.

c) Identification of miPEPS from Databases

Genomic databases of plants were searched for the presence of open reading frames within primary transcripts of 70 miRNAs, and 101 miORFs capable of encoding a miPEP were identified.

At present, AtmiPEP165a and AtmiPEP319a2, identified in Arabidopsis thaliana, have already been characterized. The experiments conducted in the model plant of tobacco made it possible to demonstrate that the overexpression of AtmiORF165a or of AtmiORF319a leads to an increase in the accumulation of AtmiR165a or of AtmiR319a respectively (FIG. 11).

miR165a regulates transcription factors such as Revoluta, Phavoluta and Phabulosa. miR319 regulates genes of the TCP family.

Example 3 Characterization in the Arabidopsis thaliana Model Plant Example 3A AtmiPEP165a

Regarding AtmiPEP165a, it has been demonstrated in vivo in Arabidopsis thaliana that treatment with AtmiPEP165a leads to a phenotype with greatly accelerated root growth (FIG. 12).

Moreover, treatment of plants with higher and higher concentrations of miPEP165a shows a dose-dependent effect on the accumulation of miR165a and the negative regulation of its target genes (PHAVOLUTA: PHV, PHABOLUSA: PHB and REVOLUTA: REV) as a function of the amount of miPEP165A (see FIG. 22).

Example 3B AtmiPEP164a

Regarding AtmiPEP164a, this was synthesized and was used for investigating an increase in the accumulation of miR164a in roots of A. thaliana treated with the synthetic peptide.

Northern blot analyses indicate that treatment of the plant with the peptide miPEP164a leads to an increase in the accumulation of miR164a (FIG. 23).

It has also been demonstrated in vivo in Arabidopsis thaliana that treatment of the plant with AtmiPEP164a increases plant growth significantly (FIG. 24).

Example 3C AtmiPEP165a

Regarding AtmiPEP165a, this was synthesized and was used for investigating an increase in the accumulation of miR165a in roots of A. thaliana treated with the synthetic peptide.

Northern blot analyses indicate that treatment of the plant with the peptide miPEP165a leads to an increase in the accumulation of miR165a (FIG. 25).

Example 4C AtmiPEP319a1

Regarding AtmiPEP319a1, this was also synthesized and was used for investigating an increase in the accumulation of miR319a in roots of A. thaliana treated with the synthetic peptide.

Analyses by qRT-PCR show that the overexpression of AtmiPEP319a1 leads to an increase in the accumulation of miR319a (FIG. 26).

It was also demonstrated in vivo in Arabidopsis thaliana that treatment of the plant with AtmiPEP319a1 increases plant growth significantly (FIG. 27).

Material and Methods Biological Material

The surface of seeds of M. truncatula was sterilized and they were left to germinate on agar plates for 5 days at 4° C. in the dark. The young shoots were then grown on 12-cm square plates filled with Fahraeus medium without nitrogen and containing 7.5 μM phosphate (Lauressergues et al., Plant J., 72(3): 512-22, 2012). The lateral roots were counted every day. In pots, the plants were watered every other day with modified Long Ashton medium with low phosphorus content (Balzergue et al., Journal of Experimental Botany, (62)1049-1060, 2011).

The peptides were synthesized by Eurogentec or Smartox-Biotech. MtmiPEP171b1 was resuspended in a solution of 40% water/50% acetonitrile/10% acetic acid (v/v/v), and the other peptides were resuspended in water.

The leaves were watered by spraying with the peptides using peptide solutions at different concentrations (0.01, 0.1, 1 μM), firstly 12 h before sampling and then a second time min before sampling.

Reverse Transcription of the microRNAs

The RNA was extracted using the reagent Tri-Reagent (MRC) according to the manufacturer's instructions, except for precipitation of the RNA, which was carried out with 3 volumes of ethanol. The everse transcription of the RNA was carried out using the specific stem-loop primer RTprimer171b in combination with hexamers for performing the reverse transcription of RNA of high molecular weight.

In brief, 1 μg of RNA was added to the stem-loop primer MIR171b (0.2 μM), the hexamer (500 ng), the buffer RT (1×), the enzyme SuperScript Reverse transcriptase (SSIII) (one unit), the dNTPs (0.2 mM each), DTT (0.8 mM) in a final reaction mixture of 25 μl. In order to carry out the reverse transcription, a reaction of pulsed reverse transcription was performed (40 repetitions of the following cycle: 16° C. for 2 minutes, 42° C. for one minute and 50° C. for one second, followed by a final inactivation of the reverse transcription at 85° C. for 5 minutes).

Analyses by Quantitative RT-PCR (qRT-PCR)

The total RNA was extracted from roots of M. truncatula or from tobacco leaves using the extraction kit RNeasy Plant Mini Kit (Qiagen). The reverse transcription was performed using the reverse transcriptase SuperScript II (Invitrogen) starting from 500 ng of total RNA. Three repetitions (n=3) were carried out, each with two technical repetitions. Each experiment was repeated from two to three times. The amplifications by qPCR were carried out using a LightCycler 480 System thermocycler (Roche Diagnostics) by the method described in Lauressergues et al. (Plant J., 72(3): 512-22, 2012).

Statistical Analyses

The mean values of the relative expression of the genes or of the production of lateral roots were analysed using the Student test or the Kruskal-Wallis test. The error bars represent the SEM (Standard Error of the Mean). The asterisks indicate a significant difference (p<0.05).

Plasmid Constructs

The DNA fragments of interest were amplified with Pfu polymerase (Promega). The DNA fragments were cloned using the XhoI and NotI enzymes into a pPEX-DsRED plasmid for an overexpression under the control of the constitutive strong promoter 35S, and using the KpnI-NcoI enzymes into a pPEX GUS plasmid for the reporter genes, by the method described in Combier et al. (Genes & Dev, 22: 1549-1559, 2008).

For the miPEPs 165a and 319a, the corresponding miORFs were cloned into pBIN19 by the method described in Combier et al. (Genes & Dev, 22: 1549-1559, 2008).

Transformation of the Plants

The composite plants having roots transformed with Agrobacterium rhizogenes were obtained by the method described in Boisson-Dernier et al. (Mol Plant-Microbe Interact, 18: 1269-1276, 2005). The transformed roots were verified and selected by observations of DsRED with a binocular fluorescence magnifier. The control roots correspond to roots transformed with A. rhizogenes not containing the pPEX-DsRED vector. Transformation of the tobacco leaves was carried out by the method described in Combier et al. (Genes & Dev, 22: 1549-1559, 2008).

Northern Blot

Northern blot analysis was carried out according to the protocol described in Lauressergues et al. Plant J, 72(3): 512-22, 2012.

The biological samples were homogenized in a buffer containing 0.1 M of NaCl, 2% of SDS, 50 mM of Tris-HCl (pH 9), 10 mM of EDTA (pH 8) and 20 mM of mercaptoethanol, and the RNA was extracted twice with a phenol/chloroform mixture and was precipitated with ethanol.

The RNA was loaded on PAGE 15% gel and transferred to a nylon membrane (HybondNX, Amersham). RNA was hybridized with a radioactive oligonucleotide probe labelled at its end, in order to detect the RNA U6 or for miR164a.

The hybridizations were carried out at 55° C. The hybridization signals were quantified using a phosphorimager (Fuji) and normalized with the signal of the specific probe of RNA U6.

Histochemical Labelling

Labelling with GUS was carried out by the method described in Combier et al., (Genes & Dev, 22: 1549-1559, 2008). The samples were observed with a microscope (axiozoom).

Immunolocalization

Roots or plantlets of tissues of Medicago were fixed for 2 hours in 4% formal (v/v) with 50 mM of phosphate buffer (pH 7.2), and then embedded in agarose LMP 5% in water (with a low melting point). Thin sections (100 μm) were obtained and were placed in Pbi (phosphate buffer for immunology) on Teflon-coated slides, blocked in Pbi, 2% Tween and 1% of bovine serum albumin for 2 hours (PbiT-BSA), then labelled overnight (12 h) at 4° C. with the primary antibody diluted in BSA-PbiT. The sections were washed with PBiT and incubated at ambient temperature for 2 h with a secondary antibody diluted in PbiT-BSA. The slides were then washed in Pbi for 30 min and mounted in Citifluor (mounting medium). The primary antibodies and the dilutions were as follows: 1716a (1:500, v/v). The secondary antibody was a goat anti-rabbit IgG antibody coupled to the Alexa Fluor 633 fluorescent probe (Molecular Probes), and was used at a dilution of 1:1000 (v/v).

B: Analysis of the miPEPs in Animals Example 4 Identification of Candidate miPEPs in Drosophila

A first study carried out by RACE-PCR in the model animal Drosophila melanogaster shows the existence of miRNAs that are expressed during embryogenesis, miR1 and miR8.

As in the plants, miORFs were identified in each of the two miRNAs studied. For example, miR8, known for its role in the regulation of growth in insects, has a miORF potentially encoding miPEP8.

Regarding DmmiR1 (identified in Drosophila melanogaster), it has two DmmiORFs potentially encoding DmmiPEP1a and DmmiPEP1b.

A phylogenetic analysis shows evolutionary conservation of the presence of the miORFs among the dozen Drosophila species analysed, i.e. since their divergence more than 60 million years ago (FIG. 13).

Moreover, the miPEPs identified in Drosophila have several similarities with the plant miPEPs. If their primary sequence and therefore their size evolve rapidly between species, a reduced size (from 32 to 104 AA) is found, as well as strong conservation for a basic overall charge (pHi from 9.5 to 12) (FIG. 14).

Taken together, these results therefore indicate the existence of regulatory miPEPs, encoded by the primary transcript of the microRNAs, over a broad spectrum of eukaryotic species. These discovered peptides represent an as yet unexplored reservoir of natural molecules that may regulate a variety of fundamental biological functions, both in plants and in animals.

Cells of Drosophila melanogaster

S2 cells are cultured in a T75 flask in 12 mL of Schneider's medium (GIBCO), containing 1% of penicillin 100 U/mL and streptavidin 100 mg/mL (Sigma) and 10% of decomplemented foetal calf serum (30 min at 56° C.).

The transient transfections are carried out using the FuGENE® HD transfection kit (Roche), according to the recommendations. Conventionally, 1.5 million S2 cells, previously seeded in 6-well plates (3 ml of medium per well), are transfected with 250 ng of total plasmid DNA. The DNA is brought into contact with the Fugene (3 μl) in 100 μl of OPTIMEM (GIBCO). After 20 minutes, the transfection reagent formed is brought into contact with the cells in the culture medium. The RNA of the cells is extracted 66 h after transfection.

C: Characterization of miPEPs in Humans Example 5 Characterization of HsmiPEP155

The DNA fragments of interest (HsmiPEP155 and the mutated miPEP) were synthesized or amplified by PCR using specific primers, and then cloned using the enzymes XhoI and NotI into a pUAS plasmid permitting their overexpression by means of the GAL4 transcription factor, the expression of which is controlled by a constitutive strong promoter.

The different constructs were produced either by PCR amplification on genomic DNA of HeLa cells, or by RT-PCR on total RNAs of L428 human cells. The amplified PCR fragments are digested with the HindIII/EcoRI restriction enzymes and then cloned into the vector pcDNA3.1. The DH5α strain of Escherichia coli is electroporated and then cultured on a solid medium (2YT+agar+ampicillin). The plasmid DNA from different clones is then prepared and sequenced for verification. The constructs are then prepared using the QIAfilter Plasmid Midi kit (QIAGEN) and stored at −20° C.

The HeLa cells (established tumour line, ATCC CCL-2.2) are cultured in a 6-well plate in complete medium [(DMEM (1×)+Glutamax+4.5 g/L glucose without pyruvate+1× penicillin/streptomycin+1 mM Na-pyruvate+10% calf serum] and placed in an incubator at 37° C. and 5% CO2.

The cells are transfected when they are at 50% confluence. At the start of the experiment, the complete medium containing the antibiotics is replaced with complete medium without antibiotics.

For each well, a mix A [250 μl of Optimem (+Glutamax) (Gibco)+2 μg of DNA] and a mix B [250 μl of Optimem+4 μl of Lipofectamine 2000 (Invitrogen)] is prepared, and left for 5 min at ambient temperature. Then mix B is mixed dropwise into mix A, and left to incubate for 25 min at ambient temperature. The mixture is then deposited dropwise into the well. 4-5 hours later, the medium is changed and replaced with complete medium with antibiotics. 48 hours after transfection, the cells are stopped. The medium is aspirated and discarded; the cells are rinsed with PBS 1×. It is then possible to store the cells at −20° C. or extract the total RNAs directly.

For each well, the RNAs are extracted by depositing 1 ml of Tri-Reagent (Euromedex) on the cells. The Tri-reagent is aspirated and returned several times so that the cells are lysed correctly, and then it is transferred into a 1.5-ml tube. 0.2 ml of water-saturated chloroform is added. It is mixed by vortexing, then left for 2 to 3 minutes at ambient temperature. It is centrifuged for 5 minutes at 15300 rpm and at 4° C. The aqueous phase is precipitated from 0.5 ml of isopropanol after incubation for 10 minutes at ambient temperature and centrifugation for 15 minutes at 15300 rpm and at 4° C. The supernatant is discarded and the pellet is rinsed with 1 ml of 70% ethanol, with centrifugation for 5 minutes at 15300 rpm at 4° C. The supernatant is again discarded and the pellet is dried for a few minutes in the air. For best-possible removal of the genomic DNA potentially remaining, the RNAs are treated with DNase. For this, the pellet is resuspended in 170 μl of ultra-pure water, 20 μl of DNase buffer 10× and 10 μl of RQ1 RNase-free DNase and held at 37° C. for 30 minutes. Then 20 μl of SDS10% and 5 μl of proteinase K (20 mg/ml) are added over 20 minutes at 37° C.

A last phenol extraction is carried out with 225 μl of a phenol/H2O/chloroform mixture, and centrifuged for 5 minutes at 15300 rpm at 4° C.

The aqueous phase is then precipitated from 20 μl of 3M sodium acetate and 600 μl of 100% ethanol for 20 minutes at −80° C. Then it is centrifuged for 15 min at 4° C. at 15300 rpm. The supernatant is discarded. The pellet is rinsed in 1 ml of 70% ethanol, centrifuged for 5 min at 15300 rpm at 4° C., the supernatant is discarded again and the pellet is left to dry for some minutes in the air.

The pellet is then taken up in 15-20 μl of ultra-pure water and the RNAs are assayed.

10-15 μg of total RNAs is then analysed by Northern blot on 15% acrylamide gel [solution of acrylamide/40% bis-acrylamide, ratio 19:1], 7M urea in TBE 1×. Migration is carried out at 400V, in TBE1× as migration buffer, after preheating the gel. The RNAs are then electro-transferred onto a Biodyne Plus 0.45 μm nylon membrane, for 2 hours, at 1V and 4° C. in a transfer tank. At the end of transfer, the membrane is irradiated with UV at 0.124 J/cm2. The membrane is then pre-hybridized in a buffer 5×SSPE, 1×Denhardt's, 1% SDS and 150 μg/ml of yeast tRNA, for 1 hour at 50° C. in a hybridization oven. Then the nucleotide probe is added, labelled at 5′ with γ-32P-ATP (0.5 to 1·106 cpm/ml of hybridization buffer) and is hybridized overnight at 50° C. The membrane is then washed twice in 0.1×SSPE/0.1% SDS at ambient temperature and exposed in an autoradiography cassette containing a BioMax HE screen (Kodak) and a BioMax MS film (Kodak), in order to detect a microRNA, for 24-48 hours, at −80° C.
