Seed Thermal Response, and Morphological and Biochemical Plasticity in Wigandia urens as Indicators of Its Utility for Elevational and Latitudinal Assisted Migration

open access: yesEcology and Evolution, Volume 15, Issue 12, December 2025.
To identify the phenotypic plasticity in germination traits related to the tolerance to changes in temperature resulting from CC and improve the successful of plant cover recovery in elevational and latitudinal gradients, we assessed the amplitude and variability of phenotypic plasticity in the seed response of W.

A single hybrid origin of cultivated peanut

open access: yesThe Plant Journal, Volume 124, Issue 6, December 2025.
SUMMARY This study, the first in a three‐part series, lays the foundation for understanding the origin of the peanut crop (Arachis hypogaea). Its subsequent evolution is explored in the two papers that follow. The evidence that A. hypogaea originated from a single hybridization event between Arachis duranensis and Arachis ipaënsis less than 10 000 ...

Ecological Strategies of Trees Across Diverse Riparian Forests Along the Tropical Rio Doce, Brazil

open access: yesAustral Ecology, Volume 50, Issue 11, November 2025.
This study investigates the functional strategies of woody plants in riparian forests along the Rio Doce, Brazil, using Grime's CSR model to examine how traits vary between adult and saplings strata across environmental gradients. Results reveal distinct ecological strategies and trait‐environment relationships in both strata, with climatic variables ...

The Sequence of Drought‐Driven Stomatal Closure, Stem Xylem Embolism, Dehydration, and Aquaporin Gene Expression Differs Among Species

open access: yesPhysiologia Plantarum, Volume 177, Issue 6, November/December 2025.
ABSTRACT Stem dehydration is critical in predicting drought‐driven tree mortality. Yet, how it coordinates with stomatal closure, xylem embolism, and aquaporin‐mediated water transport regulation remains unknown. Two angiosperms (beech and olive) and two conifers (pine and juniper) of contrasted embolism resistance were selected to assess the sequence ...
