FIG1 — Fusarium graminearum PH-1

Summary

FgFIG1 (FGRAMPH1_01G19987) on chromosome 3 of Fusarium graminearum PH-1 encodes a Dni1/Fig1 family protein. The gene is associated with ascus development, mating, and filamentous growth, as indicated by ontology annotations. Studies of related genes in other species link the Fig1 family to reduced virulence and fusarium head blight, as well as associations with Fusarium oxysporum pathovars and Verticillium dahliae. The encoded product is a membrane fusion mating protein FIG1, based on sequence similarity to characterized orthologs.
