AP1 — Triticum turgidum subsp. durum

Summary

TRITD1AV1G130800, designated AP1 in durum wheat (Triticum turgidum subsp. durum) on chromosome 1A, encodes a K-box domain-containing protein with MADS-box and MEF2-like domains. It is associated with RNA polymerase II transcription regulatory region sequence-specific DNA binding, transcription corepressor activity, and protein dimerization activity. The gene is associated with specification of floral organ and ovule identity, maintenance of inflorescence and floral meristem identity, carpel and integument development, fruit morphogenesis, and floral organ senescence. It is linked to regulation of auxin polar transport, meristem development, and root meristem size. Associations include traits such as days to flowering, photoperiod-sensitive flowering time, inflorescence and flower morphology, grain weight, heading date, seed growth and development, anthocyanin content, photosynthetic rate, and responses to high temperature, UV light, and drought.
