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

open access: yesPlant, 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.

Xanthophylls in microalgae: From biosynthesis to biotechnological mass production and application

open access: yes, 2003
Xanthophylls are oxygenated carotenoids that serve a variety of functions in photosynthetic organisms and are essential for survival of the organism. Within the last decade, major advances have been made in the elucidation of the molecular genetics and ...

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

open access: yesPlant 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.

Spatial and temporal scales in plant phenotyping for crop water stress assessment: A review

open access: yesThe Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Water stress is a major limiting factor for crop productivity worldwide, and its impacts are intensifying due to climate variability and increasing water scarcity. This review focuses on the spatial and temporal scales in plant phenotyping as a critical approach to improving crop water‐stress assessment and supporting precision water ...

Spectroscopic and photochemical properties of carotenoids, xanthophylls and model polyenes

open access: yes, 2003
The spectroscopic properties of nine all-trans-carotenoids, xanthophylls and model polyenes were studied using steady-state absorption, fluorescence, and fluorescence excitation spectroscopy. The molecules include all-trans isomers of the intermediate π-

Preharvest supplemental lighting enhances productivity and modulates postharvest quality in hydroponically grown Apulian unripe melon ‘Scopatizzo’ ( Cucumis melo L.)

open access: yesJournal of the Science of Food and Agriculture, Volume 106, Issue 13, Page 7666-7681, October 2026.
Abstract BACKGROUND Preharvest light management is increasingly used to enhance yield and fruit quality in soilless systems, yet its effects on unripe melon fruits remain poorly understood. This study evaluated the impact of supplemental red–blue light‐emitting diode (LED) lighting applied during cultivation in a closed‐cycle hydroponic system on ...

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

open access: yesPlant, Cell &Environment, Volume 49, Issue 10, Page 7590-7603, October 2026.
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.

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

open access: yesPlant Biology, Volume 28, Issue 6, Page 1796-1812, October 2026.
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

Degradation Mechanisms, Encapsulation‐Based Stabilization, and Analytical Detection of Vitamin A

open access: yesJournal of the American Oil Chemists' Society, Volume 103, Issue 9, Page 1079-1097, September 2026.
ABSTRACT Vitamin A is an important lipid‐soluble micronutrient essential for vision, immune function, and overall growth and development. However, vitamin A is unstable and susceptible to environmental factors because of its conjugated structure and inherent chemical reactivity.

Natural Compounds Targeting Oncogenic Signaling Networks in Glioblastoma: Molecular Mechanisms, Translational Advances, and Clinical Perspectives

open access: yesBrain and Behavior, Volume 16, Issue 9, September 2026.
Glioblastoma (GBM) is a highly aggressive brain tumor with a poor prognosis, driven by abnormal signaling pathways that promote growth and resistance to treatment. Conventional therapies are inadequate, highlighting the need for novel multitargeted approaches.
