Con7 is a key transcription regulator for conidiogenesis in the plant pathogenic fungus Fusarium graminearum.

ABSTRACT: The mycelium of the plant pathogenic fungus Fusarium graminearum exhibits distinct structures for vegetative growth, asexual sporulation, sexual development, virulence, and chlamydospore formation. These structures are vital for the survival and pathogenicity of the fungus, necessitating precise regulation based on environmental cues. Initially identified in Magnaporthe oryzae, the transcription factor Con7p regulates conidiation and infection-related morphogenesis, but not vegetative growth. We characterized the Con7p ortholog FgCon7, and deletion of FgCON7 resulted in severe defects in conidium production, virulence, sexual development, and vegetative growth. The mycelia of the deletion mutant transformed into chlamydospore-like structures with high chitin lev
