freB — Verticillium dahliae

Summary

VDAG_06992 (freB) in Verticillium dahliae encodes a ferric reductase transmembrane component 4, a member of the Ferric/Cupric_Reductase family with NADH:Fe3+ oxidoreductase and iron chelate reductase activities. The gene is associated with iron import into the cell, copper ion membrane transport and import, cellular response to iron ion starvation, iron homeostasis, and filamentous growth. Its product localises to the plasmalemma. Studies of related genes in other species link the family to reduced virulence and vascular wilt.
