Antioxidant activities of carotenes and xanthophylls

FEBS Letters, 1996
The purpose of this study was to assess the relative antioxidant activities of a range of carotenes and xanthophylls through the extent of their abilities to scavenge the ABTS·+ radical cation. The results show that the relative abilities of the carotenoids to scavenge the ABTS·+ radical cation are influenced by the presence of functional groups with ...

Perceptions of Medications and Supplements by U.S. Dog‐Interested Members of the Public and Final‐Year Veterinary Students

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT Veterinary graduates must be prepared to educate clients about medications and supplements. We surveyed 1955 Dog Aging Project newsletter recipients and 40 final‐year veterinary students at Texas A&M College of Veterinary Medicine and Biomedical Sciences on their perceptions about medications and supplements. Respondents indicated whether each

Diversity in xanthophyll cycle pigments content and related non-photochemical quenching (NPQ) among microalgae: implications for growth strategy and ecology [PDF]

, 2019
International audienceXanthophyll cycle‐related non‐photochemical quenching, which is present in most photoautotrophs, allows dissipating excess light energy. Xanthophyll cycle‐related NPQ depends principally on xanthophyll cycle pigments composition and

Desiccation tolerance mechanisms in the green lineage and beyond

New Phytologist, EarlyView.
Ancient origin and recurrent evolution of desiccation tolerance in the green lineage. Summary Water is essential for life on Earth, yet some plants can survive the near‐complete loss of cellular water, a trait known as desiccation tolerance. Although rare in vegetative tissues of vascular plants, desiccation tolerance is scattered across the plant ...

Identification of Genetic Loci Conveying Resistance to Fusarium oxysporum f. sp. ciceris Race 0 in Chickpea

Plant Breeding, EarlyView.
ABSTRACT Chickpea (Cicer arietinum L.) is a legume that is widely consumed around the world due to its nutritional content. Fusarium oxysporum f. sp. ciceris is a serious, destructive pathogen that causes fusarium wilt disease and affects chickpea production.

Diurnal Variations in Photochemical Energy Utilization and Osmotic Adjustments in Black Poplar Leaves Under Progressive Water Stress

Plant, Cell &Environment, EarlyView.
ABSTRACT Drought limits the productivity of fast‐growing woody crops, although the metabolic adjustments conferring water stress tolerance remain poorly understood. We investigated the responses of Populus nigra seedlings to water stress by integrating daily physiological measurements and NMR metabolomic analyses.

Antioxidants Differentially Regulate Non‐Photochemical Quenching

Plant, Cell &Environment, EarlyView.
ABSTRACT Non‐photochemical quenching (NPQ) dissipates excess light energy as heat, limiting reactive oxygen species production during photosynthesis. Exogenous antioxidants are widely reported to improve plant performance under stress, yet their impacts on NPQ are inconsistent across studies, complicating mechanistic interpretation.

Brain xanthophyll content and exploratory gene expression analysis: subspecies differences in rhesus macaque [PDF]

, 2017
BACKGROUND: The dietary xanthophylls, lutein and zeaxanthin, accumulate in primate retina and brain, and emerging evidence indicates neural lutein content may be beneficial for cognition.

Two proteins co‐expressed with photosynthetic regulators affect photosynthetic dynamics linked to changes in thylakoid pigment content and composition

Plant Biology, EarlyView.
Two factors identified by co‐expression analysis of photosynthetic regulators are described, which are involved in thylakoid pigment content and composition and, through their function, shape the dynamics of NPQ. Abstract Rapid fluctuations in light intensity require swift regulatory adjustments of photosynthesis. Although the major plant regulators of

Role of the xanthophyll cycle in photoprotection in Arabidopsis thaliana [PDF]

, 2007
The xanthophyll cycle has a major role in protecting plants from photo-oxidative stress, although the mechanism of its action is unclear. Here, Arabidopsis plants overexpressing a gene encoding {3-carotene hydroxylase, containing nearly three-times the ...
