Functional characterization of extracellular and intracellular catalase-peroxidases involved in virulence of the fungal wheat pathogen Zymoseptoria tritici.

ABSTRACT: Understanding how pathogens defend themselves against host defence mechanisms, such as hydrogen peroxide (H₂O₂) production, is crucial for comprehending fungal infections. H₂O₂ poses a significant threat to invading fungi due to its potent oxidizing properties. Our research focuses on the hemibiotrophic fungal wheat pathogen Zymoseptoria tritici, enabling us to investigate host-pathogen interactions. We examined two catalase-peroxidase (CP) genes, ZtCpx1 and ZtCpx2, to elucidate how Z. tritici deals with host-generated H₂O₂ during infection. Our analysis revealed that ZtCpx1 was up-regulated during biotrophic growth and asexual spore formation in vitro, while ZtCpx2 showed increased expression during the transition from biot
