HD3A — triticum aestivum

Summary

TRAESCS7B02G013100, also known as HD3A, VRN-B3, or TaRFT1-7B on wheat chromosome 7B, encodes a phosphatidylethanolamine-binding protein (PEBP family member). This gene is associated with phosphatidylethanolamine binding, and has been linked to a wide range of biological processes including vernalization response, photoperiodism, pre-harvest sprouting, seed maturation, shoot regeneration, and shade avoidance. It is also associated with frost tolerance, spike weight, heading time, grain dormancy, grain filling period, spikelet number, grains per spike, grain width and length, seed weight, harvest index, peduncle length, leaf width, canopy temperature, and radiation use efficiency. The protein localizes to the cytoplasm, nucleus, and endoplasmic reticulum, and participates in florigen expression and translocation pathways. Studies of related genes in other species link the family to heading date, floral meristem identity, and grain traits.
