AP1 — Triticum turgidum subsp. durum

Summary

TRITD5BV1G200510 (AP1) on durum wheat chromosome 5B encodes a K-box domain-containing protein with MADS-box and MEF2-like domains, and is associated with RNA polymerase II-specific DNA-binding transcription factor activity, transcription corepressor activity, and protein dimerization activity. The gene is associated with regulation of vernalization response, floral meristem identity, and the transition from vegetative to reproductive phase. It is linked to fruit and inflorescence development, auxin transport regulation, and root meristem size control. Associations include flowering time, photoperiod sensitivity, grain weight, heading date, and responses to high temperature, UV light, and drought. The gene is linked to seed and embryo development, leaf senescence, and chloroplast development. Studies of related genes in other species connect the family to floral organ development, inflorescence architecture, and petal and sepal development, as well as grain shape, tillering, and reproductive transition.
