Surveying Rubisco diversity and temperature response to improve crop photosynthetic efficiency

The threat to global food security of stagnating yields and population growth makes increasing crop productivity a critical goal over the coming decades. One key target for improving crop productivity and 35 yields is increasing the efficiency of photosynthesis. Central to photosynthesis is ribulose-1,5-bisphosphate carboxylase/oxygenase, Rubisco, which is a critical but often rate-limiting component. Here we present full Rubisco catalytic properties measured at three temperatures for 75 plants species representing both crops and undomesticated plants from diverse climates.
