Molecular Characterisation of the Peroxidase Gene Family in Botrytis cinerea and the Role of BcPRD7 in Virulence.

ABSTRACT: Peroxidase activity is essential for the virulence of a number of plant-pathogenic fungi. However, there are few reports of the systematic analysis of peroxidase genes in Botrytis cinerea. We identified all the peroxidase genes of B. cinerea by searching the fungal peroxidase database and found that the expression levels of BcPRD3, BcPRD7, BcPRD8 and BcPRD10 changed significantly during hyphal development and in response to H₂O₂ stress treatment and infection of Arabidopsis thaliana by B. cinerea. We found that the hyphae of the mutant strains became more slender, the number and size of the infection structures decreased, the number of conidia decreased and the stress response and virulence decreased significantly. These four genes positively regulated the growth, dev
