Abstract excerpt

MAIN CONCLUSION: S. sclerotiorum virulence is mediated by oxalic acid-induced redox imbalance. Resistant Brassica genotypes sustain antioxidant capacity and NPR1-dependent systemic acquired resistance, unlike susceptible genotypes showing transient defense responses. Stem rot caused by Sclerotinia sclerotiorum represents a major constraint to Brassica production, with oxalic acid (OA) acting as a key virulence...
