The invention relates to a method for stimulating the growth of the plants and/or improving the biomass production and/or increasing the carbon fixation by the plant comprising introducing into a plant cell, plant tissue or plant one or more nucleic acids, wherein the introduction of the nucleic acid(s) results inside the chloroplast of a de novo expression of one or more polypeptides having the enzymatic activity of a glycolate dehydrogenase made up from translationally fused subunits of bacterial multi-subunit glycolate dehydrogenase enzymes.

Method for increasing photosynthetic carbon fixation using glycolate dehydrogenase multi-subunit fusion protein

The invention relates to a method for the production of plants with suppressed photo-respiration and improved COfixation. In particular, the invention relates to a re-use of phosphoglycolate produced in photorespiration. The reaction product will be converted to a component that may be reintegrated into the plant assimilatory metabolism inside the chloroplast. This is accomplished by the transfer of genes derived from glycolate-utilizing pathways from bacteria, algae, plants and/or animals including humans into the plant nuclear and/or plastidial genome. The method of the invention leads to a reduction of photorespiration in Cplants and by this will be of great benefit for food production especially but not exclusively under non-favourable growth conditions.
