Photosynthesis serves as a global stress sensor in plants, algae and cyanobacteria. In this overview, we focus on higher plants only. Although several structural and functional components of the photosynthetic apparatus are responsive to stress, photosystem II (PS II) and ribulose-1,5-bisphosphate carboxylase oxygenase
