TL;DR: Analysis of the STn8 catalytic domain suggests that selectivity of STN8 in phosphorylation of the very N-terminal residues in D1, D2, and CP43, and Thr-4 in PsbH pre-phosphorylated at Thr-2 may be explained by the long loops obstructing entrance into the kinase active site and seven additional basic residues in the vicinity of the catalytic site.

TL;DR: Evidence that supports the mutual influence of extracellular and chloroplastic ROS production on nuclear gene regulation and how this interaction might occur is summarized.

TL;DR: STN7 kinase and the state transitions are suggested to have a physiological significance for dynamic acclimation to low but fluctuating growth light conditions and are shown to function as a buffering system upon short high light illumination peaks by shifting the thylakoids from state 2 to state 1 and thereby down regulating the induction of stress-responsive genes, a likely result from transient over-reduction of PSI acceptors.

TL;DR: The recent advances in understanding the molecular mechanisms of ozone uptake, perception and signalling pathways activated during the early steps of ozone response are discussed, and the use of ozone as a tool to study the function of apoplastic ROS in signalling is discussed.

TL;DR: Results show that UVR8 is required for transcript accumulation of genes involved in UV protection, oxidative stress, hormone signal transduction, and defense against herbivores under solar UV.
