An eco‐evolutionary optimality model explains the acclimated temperature response of photosynthesis
New Phytologist, Volume 250, Issue 5, Page 2884-2899, June 2026.Summary The optimal temperature of photosynthesis (Topt) generally increases with plant growth temperature. Changes in Topt are associated with changes in the maximum carboxylation capacity at 25°C (Vcmax25) and the maximum electron transport rate at 25°C (Jmax25). The ratio between Jmax25 and Vcmax25 declines with warming.

Sample Preparation and Separation of Lignans by Liquid Chromatography
Journal of Separation Science, Volume 49, Issue 5, May 2026.ABSTRACT Lignans are important phytochemicals found mostly in the resins of coniferous trees, but are also introduced into human diets through foods such as sesame seeds and extra‐virgin olive oil. They are pharmacologically interesting mainly because of their antioxidant activities, and they have also been shown to have cytotoxic and antimicrobial ...

Water Resources Research, Volume 62, Issue 5, May 2026.Abstract Latent heat (λ $\lambda $ET) fluxes are a major component of the hydrological cycle globally. According to recent models and experimental observations, during droughts, wetter regions respond by increasing λ $\lambda $ET, while drier regions exhibit decreasing trends due to vegetation water stress.

Elevation, rather than land use, causes important dietary shifts in the Mediterranean golden eagle
Journal of Zoology, Volume 329, Issue 1, Page 25-37, May 2026.In an ever‐changing landscape, golden eagles in the Iberian Peninsula demonstrate remarkable dietary adaptability. We monitored 50 distinct breeding events over 4 years using camera traps, collecting over 520 000 images. Elevation, rather than land use, emerged as the main driver of prey composition: lagomorphs and columbiforms dominated at lower ...

Proteometabolomic characterization of apical bud maturation in Pinus pinaster
Tree Physiology, 2020 Abstract Bud maturation is a physiological process that implies a set of morphophysiological changes that lead to the transition of growth patterns from young to mature. This transition defines tree growth and architecture, and in consequence traits such as biomass production and wood quality.

WUSCHEL Transcription Factor: From Stem Cell Maintenance to Crop Improvement
Advanced Science, Volume 13, Issue 24, 27 April 2026.This review synthesizes emerging insights into WUSCHEL (WUS) as a central regulator of plant stem cell fate beyond Arabidopsis, highlighting its roles in regeneration, somatic embryogenesis (SE), and stress adaptation across crops. It explores how WUS‐centered regulatory networks, genome editing, and AI‐guided strategies can be leveraged for precise ...

Resin acids as inducible chemical defences of pine seedlings against chewing insects.
PLoS ONE, 2020 Inducibility of defences in response to biotic stimuli is considered an important trait in plant resistance. In conifers, previous research has mostly focused on the inducibility of the volatile fraction of the oleoresin (mono- and sesquiterpenes ...
