TL;DR: Evidence that cyclic flow is essential for efficient photosynthesis is presented, by constructing mutants in Arabidopsis thaliana in which both PSI cyclic pathways are impaired, and present evidence that linear flow from water to NADP+ is commonly used.

TL;DR: A model for the regulation of CEF-PSI is proposed by WWC, in which WWC is indispensable as an electron sink for the expression of CEFs activity and the fact that CEFs cannot function independently has been demonstrated.

TL;DR: It is suggested that PSI photoinhibition is caused by both O2− and 1O2 produced within the thylakoid membranes when electron carriers in PSI become highly reduced, and it is found that not only superoxide (O2−) but also singlet oxygen (1O2) is involved in PSi photoin inhibition induced by rSP treatment.

TL;DR: Results indicated that CEF-PSI contributed to the dissipation of photon energy in excess of that consumed by photosynthesis by driving NPQ of Chl fluorescence.

TL;DR: Under drought conditions in the presence of strong light, wild watermelon accumulates high concentrations of citrulline, glutamate and arginine in its leaves, which may be related to the induction of DRIP-1, a homologue of ArgE in Escherichia coli, where it functions to incorporate the carbon skeleton of glutamate into the urea cycle.
