Fuente: WIPO "tomato" The present disclosure provides polynucleotides and polypeptides encoding green algae glycolate dehydrogenase for expression in plants. The disclosure further provides methods for introducing the polynucleotides and polypeptides in the cell of a plant for improving photosynthetic rate and/or growth and/or water use efficiency of a plant. Additionally, the disclosure provides genetically modified plants with an increased photosynthetic rate, an increased growth rate, and/or an increased water use compared to the wild-type of the genetically modified plants.
