Abstract: A method for obtaining a plant having an enriched content of cysteine and/or glutathione, including steps which consist in: transforming at least a plant cell with a vector containing an expression cassette including a sequence coding for an adenosine 5′-phosphosulphate reductase (APR); culturing the transformed cell so as to generate a plant containing in its genome the expression cassette.

Abstract: The present invention provides an expression cassette comprising a meiotically active promoter operably linked to a polynucleotide encoding a recombinational DNA repair polypeptide, or fragment thereof, wherein said polynucleotide is capable of stimulating plant meiotic recombination when expressed into RNA and/or said polypeptide.

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.

Abstract: The invention relates to a nucleic acid sequence, called “polyribozyme”, which has an endoribonuclease activity and is capable of inactivating the gene for the capsid protein of a virus, characterized in that it comprises: i) a sequence complementary to at least a part of the gene or its transcript or to its replication intermediates and, includes at distinct sites in this complementary sequence: ii) a plurality of ribozyme catalytic regions; iii) and, optionally, one or more sequences non-complementary to the transcript of the said gene, the said non-complementary sequence(s) being inserted between two consecutive bases of the complementary sequence.

Abstract: The invention concerns the identification and co-localisation between two QTL corn digestibility loci and genes involved in the synthesis of lignin, and the uses thereof in methods for producing digestible corn.

Abstract: The invention relates to novel uses of male sterility for improving the conditions for cultivating transgenic plants on behalf of man and the environment.

Abstract: Methods for the production of modified plants are provided. In these methods a first line and a second line are crossed to produce a plant having a phenotypic trait, wherein neither the first or second lines possess the phenotypic trait, and wherein at least one of the parent lines is transgenic. Plants produced by the methods of the invention are also described.

Abstract: This invention relates to a gene associated with male fertility, labeled Ms41-A, and a recessive mutant form thereof, labelled ms41-A, which confers male sterility. The Ms41-A gene is isolated from Arabidopsis, while the related gene Zm41-A is isolated from maize. Male-sterile plants are useful for the production of hybrid plants by sexual hybridization.
