Two homologous Zn2Cys6 transcription factors play crucial roles in host specificity of Colletotrichum orbiculare by controlling the expression of cucurbit-specific virulence effectors.

Abstract excerpt

Fungal plant pathogens preferentially express a set of effector genes at specific infection stages to successfully colonize the host. However, it remains unclear how effector gene expression is regulated during host infection. This study identified a Zn2Cys6 transcription factor, TFV1 (Transcription Factor for Virulence 1), whose deletion weakened virulence of Colletotrichum orbiculare on its cucurbit hosts. The...
