Zeaxanthin and Lutein: Photoprotectors, Anti-Inflammatories, and Brain Food

Molecules, 2020
This review compares and contrasts the role of carotenoids across the taxa of life—with a focus on the xanthophyll zeaxanthin (and its structural isomer lutein) in plants and humans.

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Unravelling the Intraspecific Variation in Drought Responses in Seedlings of European Black Pine (Pinus Nigra J.F. Arnold)

Plant, Cell &Environment, EarlyView.
ABSTRACT Understanding intraspecific variation in drought tolerance is essential for predicting the adaptive capacity of forest species under climate change. Yet, the molecular basis of this variation remains poorly understood in ecologically and economically important conifers.

Multiplexed Nanosensors for Real‐Time Monitoring of VOC‐Mediated Signalling Response in Plants

Plant, Cell &Environment, EarlyView.
ABSTRACT To enhance crop performance, intercropping strategies leverage volatile organic compound (VOC)‐driven interactions with companion plants that constitutively emit VOCs. Despite the agricultural importance, the mechanisms and kinetics of VOC‐mediated sensory transduction in receiver plants eavesdropping on neighbouring non‐kin emitters remain ...

Hidden Strategies Beneath a Single Nucleotide: Contrasting Physiology in Lichen Photobiont Strains

Plant, Cell &Environment, EarlyView.
ABSTRACT Lichen photobionts exhibit significant physiological variability with important ecological implications. While this variability is relatively well studied at the interspecific level, it has rarely been examined at the intraspecific level. Here, we investigated the physiological responses to temperature and irradiance of two Trebouxia lynniae ...

Screening of novel β-carotene hydroxylases for the production of β-cryptoxanthin and zeaxanthin and the impact of enzyme localization and crowding on their production in Yarrowia lipolytica

Microbial Cell Factories
Zeaxanthin, a vital dietary carotenoid, is naturally synthesized by plants, microalgae, and certain microorganisms. Large-scale zeaxanthin production can be achieved through plant extraction, chemical synthesis, or microbial fermentation.

Light‐Regulation of Zeaxanthin Epoxidase in View of the Central Role of Zeaxanthin for Photoprotection

Physiologia Plantarum
ABSTRACT Plants are frequently exposed to fluctuating light conditions and, as a consequence, to variable photo‐oxidative stress. Efficient and flexible photoprotection is therefore essential for the fitness of plants in the field. The xanthophyll zeaxanthin, which is formed in high light from violaxanthin in the xanthophyll cycle ...

Divergent structure–function coordination shapes leaf thermal tolerance in Mediterranean tree species

Plant Biology, EarlyView.
Tcrit (critical temperature) may reflect early, adaptive photoprotective downregulation of PSII in Quercus ilex, whereas in Acer campestre and Fraxinus ornus, it may more closely correspond to the onset of thermal PSII vulnerability. Abstract Increasing temperatures impair photosynthetic apparatus by damaging photosystem II (PSII) efficiency.

RESEARCH ON THE QUALITY OF SWEET CORN HYBRIDS GROWN UNDER THE CONDITIONS OF TRANSYLVANIAN PLAIN

Agricultura, 2017
Carotenoids have antioxidant functions in plant photosynthetic processes, as well as in actions of disease reduction in mammalian systems. Lutein and zeaxanthin are important dietary carotenoids.

Hyperspectral Remote Sensing Unveils Phytoplankton Succession in Hurricane Wakes

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract Hyperspectral satellite data from the NASA mission, PACE (Plankton, Aerosol, Cloud, ocean Ecosystem), can be used to investigate the effects of hurricanes on phytoplankton composition. Results from four Atlantic Ocean hurricanes show the expected increases in chlorophyll‐a concentration associated with deepening of the mixed layer depth (MLD).
