HD3A — Brachypodium distachyon

Summary

BRADI_1G48830V3 (HD3A, also known as VRN3) on chromosome 1 of Brachypodium distachyon encodes a phosphatidylethanolamine-binding protein (PEBP family). This gene is associated with the regulation of flowering time, photoperiodism, and the transition from vegetative to reproductive phase, as well as with vernalization response, photomorphogenesis, inflorescence development, and cell differentiation. It has been connected to heading time, anthesis time, maturity time, grain filling period, and plant vegetative period. The encoded protein localises to the cytoplasm, nucleus, and endoplasmic reticulum. Related genes in other species link the family to flowering time, inflorescence development, branching, and axillary meristem formation, as well as to agronomic traits including grain number, seed weight, spikelet number, heading date, and frost tolerance.
