Utilizing high‐throughput phenotyping to identify metribuzin tolerance in winter wheat

The Plant Phenome Journal, Volume 9, Issue 1, December 2026.
Abstract Plant breeders and weed scientists address weed management collaboratively by selecting for herbicide tolerance in breeding programs. Metribuzin, a Group 5 PSII‐inhibiting herbicide, is labeled for use in wheat (Triticum aestivum L.). However, application to currently available lines results in frequent, variable, and unpredictable crop injury.

Evaluation of Sunflower Sprout Extract as a Bioinspired Support to UV Filtration

ChemPhysChem, Volume 27, Issue 5, 13 March 2026.
The photochemistry of a commercial sunflower sprout extract was compared to that of pure chlorogenic acid (3‐O‐caffeoylquinic acid), a key photoprotective species found in the extract. Steady‐state and time‐resolved spectroscopy experiments revealed virtually equivalent photodynamics between aqueous solutions of the sunflower extract and chlorogenic ...
