Abstract:
1. A method for producing C 3 plants with suppressed photorespiration and improved CO 2 fixation, the method comprising introducing into a C 3 plant cell, a C 3 plant tissue or a C 3 plant one or more nucleic acid sequences, each incorporated into nuclear genomic or chloroplastic DNA by transformation, wherein said one or more nucleic acid sequences encode polypeptides having the enzymatic activities of (i) an enzyme selected from the group consisting of glycolate oxidase and glycolate dehydrogenase, (ii) glyoxylate carboligase and (iii) tartronic semialdehyde reductase, wherein said introduction results in de novo expression of polypeptides having the enzymatic activities of (i) an enzyme selected from the group consisting of glycolate oxidase and glycolate dehydrogenase, (ii) glyoxylate carboligase and (iii) tartronic semialdehyde reductase and wherein said polypeptides are localized in chloroplasts of the plant produced.
