Effect of drought and heat stresses on photosynthesis, pigments, and xanthophyll cycle in alfalfa (Medicago sativa L.)

Photosynthetica, 2020
Climate changes severely influence photosynthetic activity of plants. Studies on the combined effect of drought and heat stress on photosynthesis, pigments, and xanthophyll cycle particularly in alfalfa (Medicago sativa L.) are limited.

Citrus β-carotene hydroxylase 2 (BCH2) participates in xanthophyll synthesis by catalyzing the hydroxylation of β-carotene and compensates for BCH1 in citrus carotenoid metabolism

Horticulture Research, 2022
As an essential horticultural crop, Citrus has carotenoid diversity, which affects its aesthetic and nutritional values. β,β-Xanthophylls are the primary carotenoids accumulated in citrus fruits, and non-heme di-iron carotene hydroxylase (BCH) enzymes ...

Lutein and Zeaxanthin in the Lipid Bilayer–Similarities and Differences Revealed by Computational Studies

Frontiers in Molecular Biosciences, 2021
Lutein and zeaxanthin are two similar carotenoids of the xanthophyll subgroup. Carotenoids are synthesized almost entirely by plants but are also present in significant amounts in animals. They are essential components of the lipid matrix of biomembranes,

Is There an Optimal Combination of AREDS2 Antioxidants Zeaxanthin, Vitamin E and Vitamin C on Light-Induced Toxicity of Vitamin A Aldehyde to the Retina?

Antioxidants, 2022
Vitamins C and E and zeaxanthin are components of a supplement tested in a large clinical trial—Age-Related Eye Disease Study 2 (AREDS2)—and it has been demonstrated that they can inhibit the progression of age-related macular degeneration.

The fine-tuning of NPQ in diatoms relies on the regulation of both xanthophyll cycle enzymes

Scientific Reports, 2021
Diatoms possess an efficient mechanism to dissipate photons as heat in conditions of excess light, which is visualized as the Non-Photochemical Quenching of chlorophyll a fluorescence (NPQ).

Light quality-dependent regulation of photoprotection and antioxidant properties in rice seedlings grown under different light-emitting diodes

Photosynthetica, 2021
We examined light quality-dependent regulation of photoprotection and antioxidant properties in rice seedlings. Seedlings grown under red or green light-emitting diodes (LEDs) showed declines in quantum yield of electron transport through PSII, maximum ...
