WebJun 10, 2024 · To protect PSI under a sudden transition of light intensity, angiosperms can use several alternative electron flows to regulate the PSI redox state after an abrupt transition from low to high light, such as the CEF and the water-water cycle [17,20,33,35,50]. The CEF is considered the main way for angiosperms to flourish under fluctuating light. WebFeb 2, 2016 · The results clearly show that (1) PGR5-dependent CEF-PSI is a key regulator of a rapid photosynthetic response to high light under fluctuating light conditions and (2) …

WebDec 9, 2024 · Physiological studies revealed that expression of tetrameric PSI is favoured under high light, with an increased content of novel PSI-bound carotenoids (myxoxanthophyll, canthaxanthan and echinenone). WebCd decreased the efficiency of PSII to use the energy under high light with increasing Cd concentration. In contrast, the quantum yield of PSI did not show a significant difference among different Cd treatments. The activation of cyclic electron flow (CEF) and the inhibition of linear electron flow (LEF) due to Cd treatment were observed. things to do in lantau island

WebJul 1, 2024 · Under high light, plants should prevent PSI photoinhibition via maintaining high levels of P700 oxidation ratio (Munekage et al., 2002; Suorsa et al., 2016 ). The P700 oxidation ratio in angiosperms is mainly regulated by ΔpH ( Yamamoto et al., 2016; Armbruster et al., 2024; Takagi et al., 2024 ). WebMay 4, 2024 · Light poses a fundamental conundrum for redox balance in the PETC, mostly due to rapid and enormous fluctuations in light intensity in the natural environment. In plants, a large, energetically connected system of light-harvesting antennae concentrates light energy towards PSI and PSII, which is ideal for maximizing photosynthesis under low … Web57 minutes ago · These are affordable, reliable, and pretty high-tech, all for a budget price.
