C3 plants enhance rates of photosynthesis by reassimilating photorespired and respired CO2

Busch, Florian; Sage , Tammy L; Cousins, Asaph B; Sage, Rowan F


Photosynthetic carbon gain in plants using the C3 photosynthetic pathway is substantially inhibited by photorespiration in warm environments, particularly in atmospheres with low CO2 concentrations. Unlike C4 plants, C3 plants are thought to lack any mechanism to compensate for the loss of photosynthetic productivity caused by photorespiration. Here, for the first time, we demonstrate that the C3 plants rice and wheat employ a specific mechanism to trap and reassimilate photorespired CO2. A...[Show more]
