HD3A — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0653910 (HD3A, also known as VRN3, HvVRN3, RFT1, or HvRFT1) on barley chromosome 7H encodes a phosphatidylethanolamine-binding protein (PEBP) family member. The gene is associated with phosphatidylethanolamine binding and is linked to the regulation of flowering time, photoperiodism, and the transition from vegetative to reproductive phase. It has been connected to vernalization response, inflorescence and flower development, seed development, and cell differentiation. Associations with agronomic traits include plant vegetative period, maturity time, grain filling period, tiller number, spike length, anthesis time, and plant height. The protein localises to the cytoplasm, nucleus, and endoplasmic reticulum. Studies of related genes in other species link the family to floral meristem identity, heading date, grain traits, and frost tolerance.
