Agrestal Environments and Maternal Genetic Effects Weaken the Ecological Barriers for Crop to Wild Introgression in Sunflower

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
We highlight how agrestal environments and maternal effects may facilitate the adaptation of crop‐wild hybrid sunflower to agroecosystems. We present two consecutive years of data on diverse wild and reciprocal crop‐wild hybrid sunflower populations planted in three contrasting, ruderal or agrestal, environments. We found that (i) agrestal environments

Imaging of Molecular and Developmental Responses to Abiotic Stresses in Reproductive Tissues

open access: yesPhysiologia Plantarum, Volume 178, Issue 1, January/February 2026.
ABSTRACT Abiotic stresses, such as drought, salinity, and extreme temperatures, have profound effects on plant reproduction, often leading to reduced fertility and yield. Reproduction in plants involves complex interactions between diverse cells, necessitating spatiotemporal resolution to understand how stress impacts each component of this intricate ...

Enhanced Electroactivity for Overall Water Splitting and Oxygen Potential of Pt/Carbon Nanotubes Functionalized with Cu Organometallic Complex

open access: yesEnergy Technology, Volume 13, Issue 11, November 2025.
Functionalizing carbon nanotubes (CNT) with the mesitylcopper (Cu‐mes) complex modifies the surface of CNT, developing Cu‐Pt alloys and Cu‐species. The result is a modified Pt electronic structure that promotes the catalytic activity of the 5 wt% Pt/CNTCu‐mes nanocatalyst for hydrogen and oxygen evolution reactions, and oxygen reduction reaction.
