  • Method for obtaining a monocotyledon plant containing a gene of interest free of foreign ancillary sequence
    Patent number: 7498481
    Abstract: The present invention relates to a method for obtaining a transgenic monocotyledon plant containing a gene of interest free of foreign ancillary sequences comprising: a) transforming at least one cell of a plant having no active transposase with a vector comprising two expression cassettes, one comprising a nucleotide sequence of interest (i), the other comprising a nucleotide sequence encoding a selection marker (ii) bordered by the mobilizable sequences of a transposon, said first expression cassette (comprising the nucleotide sequence of interest (i)) being outside the transposon element; b) selecting the transformed plants with the selection marker (ii); c) crossing a transformed plant with another plant belonging to a line containing in its genome a gene encoding an endogenous active transposase, and which is in the middle of a phenotypic marker for excision (iii), to obtain an F1 or any other individual of a subsequent generation; d) selecting the cells or the individuals carrying the gene of interes

  • Method for producing modified carbon-based metabolism Cplants by overexpression of phosphoenolpyruvate carboxylase
    Patent number: 7462762
    Abstract: The invention relates to a method for producing a C4-type plant having a modified carbon metabolism, comprising the following steps: an expression cassette, which comprises a nucleotide sequence that codes for a phosphoenolpyruvate carboxylase (PEPC), is introduced into at least one cell of plant C4; the cell thus transformed is cultivated in such a way as to regenerate a C4 plant containing said expression cassette in the genome thereof.
