title: Role of thylakoid protein kinases in photosynthetic acclimation.
abstract: Photosynthetic organisms are able to adjust to changes in light quality through state transition, a process which leads to a balancing of the light excitation energy between the antennae systems of photosystem II and photosystem I. A genetic approach has been used in Chlamydomonas with the aim of elucidating the signaling chain involved in state transitions. This has led to the identification of a small family of Ser-Thr protein kinases associated with the thylakoid membrane and conserved in algae and land plants. These kinases appear to be involved both in short and long term adaptations to changes in the light environment.
