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.

Pixel‐level supervision resolves overlap: Benchmarking YOLOv12 segmentation for accurate multi‐cluster dry bean stand counting from time series unoccupied aerial systems imagery

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract An agronomic trait such as stand count is important for cultivar development and crop management practices. Manually counting the number of plants is time consuming, labor‐intensive, and prone to error. The use of unoccupied aerial systems (UAS)‐collected red, green, blue (RGB) imagery in conjunction with advanced deep learning and image ...

Optimizing light spectra for soybean cultivation in controlled environments: Effects on plant growth, flowering, seed production, and seed quality

Annals of Applied Biology, Volume 189, Issue 3, November 2026.
Cultivating soybean in a controlled environment enables precise control of growth conditions to accelerate breeding and enhance desirable traits. This study tested four LED spectra on two soybean varieties (CZ 75 70LL and S16‐14801C). The 40B:40R:20FR spectrum increased seed number by over 10% and seed weight by 20%, while both 50B:50R and 40B:40R:20FR

Morpho‐Anatomical and HPTLC Investigations of Lysimachia nummularia L. (Primulaceae) Grown in Switzerland

Microscopy Research and Technique, Volume 89, Issue 10, Page 1230-1243, October 2026.
This research provides a complete morphoanatomical description of Lysimachia nummularia, as well as a HPTLC profile. Standard techniques of light and scanning electron microscopies, as well as standard techniques of HPTLC, were used. ABSTRACT Primulaceae are distributed all over the world, encompassing around 2590 species.

Grassland forage legumes and drought mitigation – sheep wool application improved soil water availability and enhanced drought–stress responses

Journal of the Science of Food and Agriculture, Volume 106, Issue 13, Page 8073-8084, October 2026.
Abstract Background Sheep wool may reduce drought stress in grasslands when used as a soil amendment. Two experiments were conducted to explore if: (i) water absorbed by wool would be biologically ‘active’ and therefore available to plants, using a novel method of measuring water activity (a w); and, (ii) adding wool to compost would delay water stress
