WebNon-photochemical quenching (NPQ) plays a major role in photoprotection. Anastatica hierochuntica is an annual desert plant found in hot deserts. We compared A. hierochuntica to three other different species: Arabidopsis thaliana, Eutrema salsugineum and Helianthus annuus, which have different NPQ and photosynthetic capacities.
WebEsa Tyystjärvi, in International Review of Cell and Molecular Biology, 2013. 6.6.3 Effect of NPQ. NPQ would protect against all mechanisms that depend on light absorbed by the PSII antenna (mechanisms 1, 2, 5–7). The protective efficiency of NPQ would be moderate against mechanisms 1, 6 and 7 because electron transfer through PSII, and accordingly … WebJun 17, 2024 · The simple relationship between NPQ and Dtx is expected if Dtx itself is a homogenous Stern–Volmer quencher 42, however, other more complex NPQ models have been proposed, involving two different ...

WebApr 1, 2001 · NPQ can be divided into at least three different components according to their relaxation kinetics in darkness following a period of illumination, as well as their response to different inhibitors (Fig. 2; Horton and Hague, 1988). The major and most rapid component in most algae and plants is the pH- or energy-dependent component, qE.
WebApr 8, 2024 · To do so, we compared the NPQ levels induced by either high light or acetic acid in cells with different amounts of LHCSRs. In wild-type C. reinhardtii, the expression level of LHCSR1 and LHCSR3 changes dramatically under different growth conditions, leading to different NPQ levels (26–28). fly me to the moon bayonetta lyricsWebEsa Tyystjärvi, in International Review of Cell and Molecular Biology, 2013. 6.6.3 Effect of NPQ.

It involves the quenching of singlet excited state chlorophylls (Chl) via enhanced internal conversion to the ground state (non-radiative decay), thus harmlessly dissipating excess excitation energy as heat through molecular vibrations.
