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.

Remote Sensing in Ecology and Conservation, EarlyView.We demonstrate that high‐resolution multispectral imagery combined with machine learning can accurately predict key biocrust functional indicators, particularly the UV‐protective pigment scytonemin, across dryland ecosystems. Using fine‐scale imagery acquired in the Chihuahuan Desert and Colorado Plateau, we identified spectral bands strongly ...

The protective function of the xanthophyll cycle in photosynthesis [PDF]
, 1994 The rapid conversion of the carotenoid violaxanthin to zeaxanthin via antheraxanthin (xanthophyll cycle) in potato leaves exposed at 23°C to a strong white light of 2000 μE·M−2·S−1 was associated with a slight inhibition of photosynthetic electron ...

Staging concept for aging management: Definition, mechanism, and coping strategies
VIEW, EarlyView.We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Ocular Manifestations of Metabolic Syndrome: A Systemic Vascular Phenotype
Diabetes, Obesity and Metabolism, EarlyView.ABSTRACT Context Metabolic syndrome (MetS) is defined by central obesity, insulin resistance, hypertension and dyslipidemia. MetS affects over one‐third of US adults. Beyond its cardiovascular burden, MetS has clinically relevant associations with ocular health and may contribute to a systemic vascular and neuro‐metabolic phenotype involving the retina,

Assessing Ecosystem Isoprene Emissions by Hyperspectral Remote Sensing
Remote Sensing, 2018 This study examined the relationship between foliar isoprene emissions, light use efficiency and photochemical reflectance index (PRI) throughout the canopy profile and explored the contribution of xanthophyll cycle pigments versus other carotenoid ...

Selected factors affecting the metabolism of xanthophyll in chickens [PDF]
, 1966 Consumer demands for chickens with deep yellow skin color and for eggs with moderately yellow yolks have been evident for many years. The degree of pigmentation desired varies considerably according to locations throughout the United States and the world.

Carotenoid Biosynthesis in Fusarium
Journal of Fungi, 2017 Many fungi of the genus Fusarium stand out for the complexity of their secondary metabolism. Individual species may differ in their metabolic capacities, but they usually share the ability to synthesize carotenoids, a family of hydrophobic terpenoid ...
