MYCGR3G51498 — Zymoseptoria tritici

Summary

MYCGR3G51498, designated yap1 in Zymoseptoria tritici on chromosome 13, encodes a bZIP transcription factor with DNA-binding transcription activator activity specific to RNA polymerase II and cis-regulatory region binding. The protein localises to the nucleus, cytoplasm, and transcription regulator complexes. In this species, yap1 is associated with sexual and asexual sporulation, cellular response to oxidative stress, positive regulation of transcription by RNA polymerase II, and carbohydrate metabolism. It is also linked to the anabolism of emericellin, shamixanthone, and sterigmatocystin, as well as the inhibition of asperthecin formation and downregulation of emericellin biosynthesis. Studies of related genes in other species link the family to oxidative stress tolerance, a trait also connected to this gene.
