HP1 — Verticillium dahliae

Summary

VDAG_08956 (HP1) in Verticillium dahliae encodes a cerato-ulmin hydrophobin family protein, classified as an apoplastic effector. The gene is associated with capsule organization, conidia formation, hyphal growth, spore formation, and methylation. Its product localizes to the cytoplasmic vesicle, hyphal cell wall, vacuole, and extracellular space. HP1 has been connected to vascular wilt disease in Gossypium hirsutum (cotton). Studies of related genes in other species link the family to reduced virulence and unaffected pathogenicity, as well as to fusarium head blight in Triticum aestivum (wheat).
