Abstract:The fungusParastagonospora nodorumcauses septoria nodorum blotch on wheat. The role of the fungal Velvet-family transcription factor VeA inP. nodorumdevelopment and virulence was investigated here. Deletion of theP. nodorum VeAortholog,PnVeA, resulted in growth abnormalities including pigmentation, abolished asexual sporulation and highly reduced virulence on wheat. Comparative RNA-Seq and RT-PCR analyses revealed that the deletion ofPnVeAalso decoupled the expression of major necrotrophic effector genes. In a… Show more
