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

open access: yes, 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

Astaxanthin and Related Xanthophylls

open access: yes, 2014
This chapter describes astaxanthin and other xanthophylls, which are a class of carotenoids with oxygenated groups in their structure and characteristic vivid colors. Taking astaxanthin as a key example, the presented concepts focus on the functional aspects and applications of xanthophylls, such as their nutritional value, potential for protection ...

Exogenous Calcium Alleviates Photoinhibition of PSII by Improving the Xanthophyll Cycle in Peanut (Arachis Hypogaea) Leaves during Heat Stress under High Irradiance

open access: yesPLoS ONE, 2013
Peanut is one of the calciphilous plants. Calcium (Ca) serves as a ubiquitous central hub in a large number of signaling pathways. The effect of exogenous calcium nitrate [Ca(NO3)2] (6 mM) on the dissipation of excess excitation energy in the photosystem

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

open access: yesPlant, 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.

Utilization and Yolk Coloring Capability of Xanthophylls from Synthetic and High Xanthophyll Concentrates

open access: yesPoultry Science, 1985
Abstract Four marigold products, a bixin product, and two synthetic xanthophylls, canthaxanthin and β-apo-8′-carotenal, were evaluated for their effects on xanthophyll utilization and coloring capability in egg yolks. The selected sources, obtained as commercially available products, were added to a yellow corn basal diet containing 11 mg total ...

Impact of emerging compound droughts on forests: A water supply and demand perspective

open access: yesPlant Biology, EarlyView.
This review examines the physiological and ecological responses of trees to emerging compound droughts from a water demand and supply perspective, as well as the role of acclimation and consequences for ecosystem‐level functions. Abstract The intensification of climate change‐induced drought results in unprecedented tree and forest die‐offs worldwide ...

Effects of Cobalt and Zinc Stress on Rehmannia glutinosa Growth, Bioactive Compounds, Antioxidant Activity, and Molecular Insights

open access: yesNew Zealand Journal of Crop and Horticultural Science, Volume 54, Issue 1, March 2026.
This study aimed to investigate the effects of cobalt (Co) and zinc (Zn) on the growth, antioxidant activity, total phenolic and flavonoid contents (TPC and TFC), targeted polyphenolic compounds, and molecular dynamics simulations of Rehmannia glutinosa (R. glutinosa) L.

Alfalfa‐Based Dehydrated Silage Pellet as a Source of Nutrients in Laying Hens: I. Effects on Animal Performance and Egg Quality

open access: yesVeterinary Medicine and Science, Volume 12, Issue 2, March 2026.
Alfalfa‐based silage pellets (ABSP) showed significant results regarding production performance, yolk colour and ω‐3 (PUFAs), as well as the ratio ω‐6/ω‐3 (p < 0.05). The ABSP group also exhibited a higher abundance of beneficial bacteria and a lower abundance of pathogenic bacteria compared to the control group (p < 0.05).
