GcQCR7 Mediates Pathogenicity via Maintaining Cell Wall Integrity and Enhancing Oxidative Stress Tolerance in Glomerella cingulata
This study demonstrates that the mitochondrial subunit GcQCR7 is essential for *Glomerella cingulata* pathogenicity by maintaining cell wall integrity, energy metabolism, and oxidative stress tolerance, thereby identifying it as a novel target for managing Glomerella leaf spot in apple production.
