AP1 — Triticum turgidum subsp. durum

Summary

TRITD6BV1G003010, also known as TtAP1, encodes a MADS-box transcription factor containing a MADS-box and K-box domain. It is localized to the nucleus and has molecular functions including RNA polymerase II transcription regulatory region sequence-specific DNA binding, RNA polymerase II cis-regulatory region sequence-specific DNA binding, DNA-binding transcription factor activity (RNA polymerase II-specific), and protein dimerization activity. In durum wheat, this gene is associated with flower development, carpel development, specification of ovule identity, indeterminate inflorescence morphogenesis, reproductive structure development, post-embryonic development, regulation of developmental process, regulation of transcription by RNA polymerase II, positive regulation of transcription by RNA polymerase II, plant ovule development, cell differentiation, and DNA-dependent transcription. It has also been linked to anthesis time and grain yield. Studies of related genes in other species, such as SOC1 and CAL, connect the family to flowering time regulation and floral organ identity.
