Abstract

Source and sink strength control plant carbon gain and yield. Source strength was recently engineered by modifying the large subunit of Rubisco, replacing the small subunit, and creating improved thermostable Rubisco activases. This technological breakthrough makes Rubisco engineering feasible at last. Enhancement of leaf transitory starch synthesis or induction of artificial sinks in leaves increased biomass and yield. Importantly, such approaches also had a positive feedback on source strength. In addition, novel targets for the improvement of carbon gain in crops have been identified that are especially relevant in the light of climate change.
