Abstract
The relative rates of photosynthesis and photorespiration in soybean are determined by the kinetic properties of ribulose 1,5-diphosphate (RuDP) carboxylase. Carbon dioxide and oxygen compete for RuDP at the carboxylase. High CO2 and low O2 favor carboxylation of RuDP to 3-phosphoglycerate, thereby promoting photosynthesis. Low CO2 and high O2 concentrations favor oxygenation of RuDP to P-glycolate, thereby promoting photorespiration. In maize, the phosphopyruvate carboxylase - malic enzyme couple acts to increase the CO2 concentration in the bundle sheath cells, site of RuDP carboxylase in C4 species. Maize RuDP carboxylase is also sensitive to O2, so this increased CO2 concentration in the bundle sheath stimulates photosynthesis and reduces photorespiration. Since photorespiration and an associated oxygen inhibition of photosynthesis markedly inhibit net photosynthesis in soybean under standard atmospheric conditions of 300 ppm CO2 and 21% O2, and since no required role for photorespiration has been demonstrated, attempts are being made to reduce or eliminate photorespiration in the soybean and other C3 crop species.
