abaA — Fusarium graminearum PH-1

Summary

FGRAMPH1_01G02219 (symbol abaA) on chromosome 1 of Fusarium graminearum PH-1 encodes a TEA/ATTS domain-containing transcription factor. The protein has DNA-binding transcription factor activity and is localised to the nucleus and transcription regulator complex. The gene is associated with the positive regulation of phialide development, conidium formation, and asexual sporulation, as well as conidiophore development, conidium germination, autolysis, hyphal growth, cell morphogenesis, sexual reproduction, secondary metabolism, and spore formation. Studies of related genes in other species link the family to loss of pathogenicity, unaffected pathogenicity, and reduced virulence.
