  • Publication number: 20240229050
    Abstract: The invention provides a method for producing a plant cell modified at a targeted site of a double-stranded DNA, including (i) a step of providing a plant cell comprising the double-stranded DNA of interest, (ii) a step of providing a complex in which a nucleic acid sequence-recognizing module that specifically binds to a target nucleotide sequence in the double-stranded DNA and a DNA glycosylase with sufficiently low reactivity with the double-stranded DNA are bound, (iii) a step of placing the complex in a condition under which the plant cell is transfected, (iv) a step of placing the transfected plant cell in a condition that induces modification of the targeted site, without cleaving at least one strand of the double-stranded DNA in the targeted site, and (v) a step of selecting a cell into which the complex has been introduced and/or a cell into which the modification has been introduced.

  • Publication number: 20220411812
    Abstract: The present invention provides a method for improving salt tolerance of a plant so as to enable the plant to be cultivated under a high salt concentration condition. The present invention discloses a method for improving salt tolerance of a plant, including suppressing or inhibiting a function of PERK13 (Proline-rich extensin-like receptor kinase 13) in a plant; the method for improving salt tolerance of a plant, wherein an antagonist of PERK13 is brought into contact with a root of the plant; the method for improving salt tolerance of a plant, wherein the antagonist is one or more species of microorganisms or a secretion therefrom; and the method for improving salt tolerance of a plant, wherein the suppression of the function of the PERK13 is carried out by suppressing expression of PERK13 gene, or the inhibition of the function of the PERK13 is carried out by inhibiting expression of PERK13 gene.

  • Publication number: 20220119828
    Abstract: The present invention provides a nucleic acid comprising: (1) a transposon; and (2) a sequence homologous to at least a part of a target region of a double-stranded DNA of a plant cell, wherein the transposon comprises a marker gene and a gene encoding a transposase operably linked to an inducible promoter.

  • Patent number: 11220693
    Abstract: The present invention provides a method of modifying a targeted site of a double stranded DNA of a monocot cell, comprising a step of contacting a complex wherein a nucleic acid sequence-recognizing module that specifically binds to a target nucleotide sequence in the given double stranded DNA and a nucleic acid base converting enzyme are bonded, with said double stranded DNA, to convert one or more nucleotides in the targeted site to other one or more nucleotides or delete one or more nucleotides, or insert one or more nucleotides into said targeted site, without cleaving at least one strand of said double stranded DNA in the targeted site, wherein the double stranded DNA is contacted with the complex by introducing a nucleic acid encoding the complex into the monocot cell.

  • Publication number: 20200377910
    Abstract: The present invention provides a method of modifying a targeted site of a double-stranded DNA, comprising a step of introducing a complex wherein a nucleic acid sequence-recognizing module that specifically binds to a target nucleotide sequence in a double-stranded DNA and PmCDA1 are bonded, into a cell containing the double-stranded DNA, and culturing the cell at a low temperature at least temporarily to convert the targeted site, i.e., the target nucleotide sequence and nucleotides in the vicinity thereof, to other nucleotides, or delete the targeted site, or insert nucleotide into the site.
