Isoleucine 309 acts as a C 4 catalytic switch that increases ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco) carboxylation rate in Flaveria

Whitney, Spencer; Sharwood, Robert; Orr, Douglas; White, Sarah; Alonso, Hernan; Galmes, Jeroni


Improving global yields of important agricultural crops is a complex challenge. Enhancing yield and resource use by engineering improvements to photosynthetic carbon assimilation is one potential solution. During the last 40 million years C4 photosynthesis has evolved multiple times, enabling plants to evade the catalytic inadequacies of the CO2-fixing enzyme, ribulose-1,5-bisphosphate carboxylase/oxygenase (rubisco). Compared with their C3 ancestors, C4 plants combine a faster rubisco with a...[Show more]
