SUMMARY There is a need for ground‐breaking technologies to boost crop yield, both grains and biomass, their processing into economically competitive materials. Novel cereals with enhanced photosynthesis assimilation of greenhouse gasses, such as carbon dioxide ozone, tailored straw suitable industrial manufacturing, open new perspective the circular economy. Here we describe vision, strategies, objectives BEST‐CROP, Horizon‐Europe United Kingdom Research Innovation (UKRI) funded project that relies on an alliance academic plant scientists teaming up breeding companies use major advances in photosynthetic knowledge improve barley biomass exploit variability quality composition. We adopt most promising strategies properties ozone capacity barley: (i) tuning leaf chlorophyll content modifying canopy architecture; (ii) increasing kinetics responses changes irradiance; (iii) introducing photorespiration bypasses; (iv) modulating stomatal opening, thus rate fixation assimilation. expect by improving our targeted traits will achieve increases aboveground total production without modification harvest index, added benefits sustainability via better resource‐use efficiency water nitrogen. In parallel, resulting to: increase protein make it development alternative biolubricants feed sources; control cellulose/lignin contents lignin develop straw‐based construction panels polymer composites. Overall, exploiting natural‐ induced‐genetic well gene editing transgenic engineering, BEST‐CROP lead multi‐purpose next generation cultivars supporting sustainable agriculture capable applications.

Pest Management Science, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 10, 2025

Wheat powdery mildew is an airborne multi-cycle disease caused by Blumeria graminis f. sp. tritici. This can cause severe yield reduction or total crop loss. Fluopyram a succinate dehydrogenase inhibitor (SDHI) used for the prevention and control of gray mold, mildew, downy in fruits vegetables. We fluopyram to treat wheat seeds demonstrated excellent mildew. treatment did not affect seed germination. After treatment, residual amounts harvested grains soil were lower than maximum residue limit (MRL, 0.07 mg kg-1). explored mechanism action on using eukaryotic reference transcriptome analysis. The differentially expressed genes (DEGs) plants treated with mostly enriched photosynthesis pathway. SPAD (soil-plant analysis development) value measurements showed significant increase chlorophyll content after treatment. enzyme activity chitinase relative expression levels related (Cht3 Cht4) significantly up-regulated, indicating that defense response was activated. expected be developed research this study will provide important theoretical basis controlling tritici field. © 2025 Society Chemical Industry.
