Webxanthophyll cycle can be observed at all three levels of organization. The analyses of the rate of induction of quenching in all systems suggest a qE mechanism that controls this … WebJul 19, 2013 · Photochemistry, remotely sensed physiological reflectance index and de-epoxidation state of the xanthophyll cycle in Quercus coccifera under intense drought. …
WebZeaxanthin is formed in thylakoids by reversible de-epoxidation of violaxanthin in a process called the xanthophyll cycle (Yamamoto et al., 1962), ... showed correlations between … WebThe conversion of violaxanthin (Vx) to zeaxanthin (Zx) in the de-epoxidation reaction of the xanthophyll cycle plays an important role in the protection of chloroplasts against photooxidative damage. Vx is …
WebThis index indicates the kinetic changes in the de-epoxidation state of the xanthophyll cycle that directly correlates with the A+Z content. Total carotenoids were calculated as the sum of neoxanthin (N), V, A, L, Z, and β-C. The results are expressed and discussed on a dry weight (DW) basis for chlorophylls (Figure 2b and 6a) VAZ (Figure 6b ... WebMay 1, 1991 · A linear relationship between Δ A 505 and the decrease in the epoxidation state of the xanthophyll-cycle pigment pool was obtained over the range 10–40° C. The maximal rate of de-epoxidation was strongly temperature dependent; Q 10 measured around the temperature at which the leaf had developed was 2.1–2.3 in both species.
WebChanges in the de-epoxidation state (DEPS) of xanthophyll cycle pigments can be observed as changes in the leaf absorption of light with wavelengths between 500 to 570 nm.
WebIntense light induced increased non-photochemical quenching (NPQ) and stimulated de-epoxidation of xanthophyll cycle components, while DTT-treated samples had lower NPQ capacity, indicating that the xanthophyll cycle must participate in photoprotection. In this work, we found that the PsbS-related NPQ was maintained in U. prolifera. convert 35000 birr to usdWebMay 22, 2024 · In higher plants, the xanthophyll cycle is triggered by luminal acidification and is mediated by the violaxanthin de-epoxidase (VDE) enzyme, which converts violaxanthin into zeaxanthin in two de-epoxidation steps, forming antheraxanthin as … convert 350 aud to gbpWebThe Xanthophyll Cycle Under conditions of excess light, violaxanthin is de-epoxidized to zeaxanthin via the monoepoxide antheraxanthin due to the activation of violaxanthin de-epoxidase, a thylakoid lumen enzyme.
