ChCcp1 and ChCyc1 function as a coordinated redox couple to regulate asexual sporulation, pathogenicity, and oxidative/osmotic stress adaptation in Cochliobolus heterostrophus.
BACKGROUND Cytochrome c peroxidase (Ccp) is a critical enzymatic component in the fungal oxidative stress response and cellular redox homeostasis. However, the biological roles and regulatory mechanism of Ccp in Cochliobolus heterostrophus-a major necrotrophic pathogen responsible for Southern corn leaf blight-remain p...
