Cutting-edge research revealed mechanisms in plant immunity and agricultural sustainability. Studies uncovered a root-based N-hydroxypipecolic acid circuit enhancing Arabidopsis immunity and growth, while elucidating the pathway for salicylic acid synthesis from phenylalanine in rice, deepening understanding of plant defense. Agrivoltaics demonstrated improved photosynthesis under midday heat in drylands, and European bio-based farming collaboration promotes sustainable practices. These findings support innovations in crop protection and climate-resilient farming systems.
