A complete MAP kinase cascade controls hyphopodium formation and virulence of Verticillium dahliae.

ABSTRACT: Phytopathogens develop specialized infection-related structures to penetrate plant cells during infection. Different from phytopathogens that form appressoria or haustoria, the soil-borne root-infecting fungal pathogen Verticillium dahliae forms hyphopodia during infection, which further differentiate into penetration pegs to promote infection. The molecular mechanisms underlying the regulation of hyphopodium formation in V. dahliae remain poorly characterized. Mitogen-activated protein kinases (MAPKs) are highly conserved cytoplasmic kinases that regulate diverse biological processes in eukaryotes. Here we found that deletion of VdKss1, out of the five MAPKs encoded by V. dahliae, significantly impaired V. dahliae hyphopodium formation, in vitro penetrat
