HD3A — Triticum turgidum subsp. durum

Summary

TRITD7AV1G033560 (HD3A) on durum wheat chromosome 7A encodes a phosphatidylethanolamine-binding protein (PEBP-like superfamily) with FT-like protein characteristics. This gene is associated with the regulation of flowering time, including photoperiodism, vernalization response, and the transition from vegetative to reproductive phase. It is linked to inflorescence development, flower development, and cell differentiation, as well as responses to short-day conditions. Associations with agronomic traits include anthesis time, maturity time, grain filling period, spike length, node number, plant vegetative period, and grain yield. The encoded protein localizes to the cytoplasm, nucleus, and endoplasmic reticulum. Studies of related genes in other species link the family to heading date, floral development, grain traits, and frost tolerance.
