Abstract: The present disclosure relates to a transgenic plant cell comprising polynucleotide sequences encoding glycolate dehydrogenase, malate synthase, and an inhibitory polynucleotide targeting an endogenous glycolate transporter Plgg1, wherein expression of endogenous glycolate transporter Plgg1 in the transgenic plant cell is about 20% to 80% of expression of endogenous glycolate transporter Plgg1 in a plant cell that is not transformed with an inhibitory polynucleotide targeting an endogenous glycolate transporter Plgg1. Also disclosed are transgenic plants, transgenic plant cultures, and methods for increasing photosynthesis efficiency in plants. The disclosed methods enhance biomass productivity and reduce the negative impact of photorespiration and introduction of transgenic constructs on plant growth.
