TRI1 — Fusarium graminearum PH-1

Summary

FgTRI1 (FGRAMPH1_01G18731) on chromosome 3 of Fusarium graminearum PH-1 encodes a protein containing SWIB/MDM2 and DEK_C domains, with general RNA polymerase I transcription factor activity and sequence-specific DNA binding to the Pol I cis-regulatory region. The gene is associated with transcription initiation from the Pol I promoter, rRNA transcription, and localisation to the UAF complex, nucleus, and cytosol. It is linked to phytoalexin biosynthesis, jasmonic acid signaling, innate immunity, mycotoxin anabolism, secondary metabolism, sporulation, spore germination, sexual reproduction, hyphal growth, and detoxification. Associations with traits include glucose and phosphate content. Phenotypic connections include altered cell cycle progression, meiotic recombination, spore wall formation, radiation resistance, osmotic stress resistance, and decreased colony size and vegetative growth.
