TL;DR: It is proposed that regulation of PSII photoinhibition is the ultimate regulator of the photosynthetic electron transfer chain and provides a photoprotection mechanism against formation of reactive oxygen species and photodamage in PSI.

TL;DR: Coordinated function of thylakoid protein kinases and phosphatases is shown to secure balanced excitation energy for both photosystems by preventing state transitions upon changes in light intensity and shows that there is a close cooperation between the redox- and proton gradient-dependent regulatory mechanisms for proper function of the photosynthetic machinery.

TL;DR: Investigation of inhibitory effects of 3 major PAH particularly on photosynthetic processes in Arabidopsis thaliana grown in soil treated with PAH found that 3-ring anthracence is more inhibitory as compared to 2-ring naphthalene and 4-ring pyrene, indicating that aromaticity of PAH is unrelated to their response on photosynthesis processes.

TL;DR: The results of this study suggest that the control of excitation energy transfer interacts with hormonal regulation, and the Photosynthetic pigment–protein complexes appear to operate as receptors that sense the energetic balance between the photosynthetic light reactions and downstream metabolism.

TL;DR: The proposition that mild heat stress triggers state transitions in the dark similar to light-induced state transitions, which involve phosphorylation of LHCII by STN7 kinase is supported.
