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 … 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 ).

WebApr 24, 2024 · Within the first 10 s after transition from low to high light, cyclic electron flow (CEF) around PSI was highly stimulated at 25 °C but was slightly activated at 42 °C. Such … 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). center high mount brake light
Moderate heat stress accelerates photoinhibition of photosystem …
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 … WebJan 1, 2024 · If the ΔpH formation under high light was impaired, the excess electron flow from photosystem II (PSII) would induce the over-reduction of photosystem I (PSI), causing photoinhibition of PSI ( Suorsa et al., 2012; Kanazawa et al., 2024 ).
