A metabolic bypass increases crop productivity
Carbon fixation is a notoriously inefficient process in land plants. The key enzyme of carbon fixation, ribulose-1,5-bisphosphate carboxylase-oxygenase (RuBisCO), can also react with oxygen, generating 2-phosphoglycolate. This molecule is toxic and has to be remediated by photorespiration, a costly metabolic route and result in a net loss of energy and of carbon to CO2, which could otherwise have been assimilated into biomass. In a recent work, researchers from the University of Illinois, Urbana, inserted into tobacco plants a synthetic metabolic pathway that bypasses photorespiration. They showed that the transformed plants display increased photosynthetic capacity and biomass yield in field trials.
