TRI13 — Fusarium culmorum CS7071

Summary

FCUL_05972.1 (TRI13) on chromosome 2 of Fusarium culmorum encodes a cytochrome P450 monooxygenase, a heme-binding oxidoreductase that acts on paired donors with incorporation of molecular oxygen and binds iron. The gene is associated with mycotoxin and fumonisin anabolism, small molecule biosynthesis, secretion, and genetic transfer, and its product localises to the membrane. Related genes in other species link the family to further secondary metabolite biosynthesis. TRI13 is also connected to T-2 toxin production via the TRI13 protein, to fumonisin B1 through FUM15, and to fumonisin B2 through sphH, underscoring its relevance to mycotoxin accumulation in this cereal pathogen.
