Understanding the Changes in the Circular Dichroism of Light Harvesting Complex II upon Varying Its Pigment Composition and Organization [PDF]

, 2007
In this work we modeled the circular dichroism (CD) spectrum of LHCII, the main light harvesting antenna of photosystem II of higher plants. Excitonic calculations are performed for a monomeric subunit, taken from the crystal structure of trimeric LHCII ...

Esterification enhances carotenoid retention during bread‐making

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Carotenoids are plant‐derived antioxidants that contribute to human health and represent key quality traits in wheat‐based foods. However, they are highly unstable and prone to degradation during processing. Xanthophyll esterification has been identified as a natural mechanism that enhances carotenoid stability during grain storage.

Comparison between fluorometry and microscopy‐based phytoplankton assessments in the Laurentian Great Lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.

High‐throughput transcriptome mining and in silico screening reveal saccharide feeding stimulants for Cydia pomonella larvae

New Plant Protection, EarlyView.
We identified and characterized the gustatory and ionotropic receptors of Cydia pomonella using transcriptomics and in silico approaches, linking candidate sugar receptors to larval feeding attraction. Functional assays and behavioral tests highlighted isoquercitrin as a key feeding stimulant, providing a foundation for olfactory‐ and taste‐based pest ...

The impact of selected xanthophylls on oil hydrolysis by pancreatic lipase: in silico and in vitro studies

Scientific Reports
Lipase inhibition is one of the directions to control obesity. In vitro assays have confirmed the inhibitory effect of selected xanthophylls, including astaxanthin, fucoxanthinol, fucoxanthin, and neoxanthin.

Biosynthesis and Degradation of Carotenoids in Ornamental Crops with specific reference to Chrysanthemum [PDF]

, 2017
Carotenoids are lipophilic secondary metabolites derived from the isoprenoid pathway, accumulated in most plant organs and widely used as an antioxidant. Carotenoids synthesized in chloroplasts are essential for protecting tissues against photo-oxidative

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

PLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.

Deposition of carotenoids in egg yolk by short-term supplement of coloured carrot (Daucus carota) varieties as forage material for egg-laying hens [PDF]

, 2010
BACKGROUND: Supplying egg-laying hens with different forage materials may influence egg production and quality. The aim of this study was to examine the short-term effects of standard feed plus 70 g day−1 per hen of three coloured carrot varieties ...
