Biochar application alleviates drought-induced oxidative stress by activating the salicylic acid-mediated glutathione synthesis pathway in Brassica napus.

Biochar Boosts Drought Tolerance in Rapeseed by Activating Salicylic Acid-Driven Glutathione Pathway

New research reveals that biochar significantly reduces drought-induced oxidative stress in Brassica napus by enhancing salicylic acid signaling and activating glutathione biosynthesis. The study shows how biochar improves water status, suppresses harmful ROS, and restores redox balance through the SA-mediated GSH pathway.
