The Cys2 -His2 (C2H2) zinc finger protein family is the second-largest family of transcription factors (TFs) in Magnaporthe oryzae, the causal fungus responsible for the destructive rice blast disease. However, little is known about the roles of most C2H2 TFs in the development and pathogenicity of M. oryzae. The roles of 47 C2H2 genes in development and pathogenicity were investigated by gene deletion in M. oryzae. The TF-dependent genes in mycelia or appressoria were analyzed with RNA sequencing and quantitative PCR (qPCR). Forty-four C2H2 genes are involved in growth (20 genes), conidiation (28 genes), appressorium formation (four genes) and pathogenicity (22 genes) in M. oryzae. Of these, MGG_14931, named as VRF1, is required for pathogenicity, specifically controlling appressorium maturation by affecting the expression of genes related to appressorial structure and function, including melanin biosynthesis, chitin catabolism, lipid metabolism, proteolysis, transmembrane transport, and response to oxidative stress; MGG_01776, named as VRF2, is required for plant penetration and invasive growth; conidiation-related gene CON7 is required for conidial differentiation; and MoCREA, encoding a carbon catabolite repression protein, is a novel repressor of lipid catabolism when glucose obtainable in M. oryzae. This study provides many insights into the regulation of growth, asexual development, appressorium formation, and pathogenicity by C2H2 TFs in M. oryzae
