VRN3 — Brachypodium distachyon

Summary

BRADI_3G08890V3 (VRN3) on chromosome 3 of Brachypodium distachyon encodes a phosphatidylethanolamine-binding protein (PEBP family), with annotated molecular function in phosphatidylethanolamine binding. The gene is associated with the regulation of flowering time, including photoperiodism, the transition from vegetative to reproductive phase, inflorescence and flower development, and vernalization response. It is linked to both upregulation of vernalization response and downregulation of flower development, as well as to memory, response to short-day conditions, and cell differentiation. The encoded protein localises to the cytoplasm, nucleus, and endoplasmic reticulum. VRN3 is also associated with anthesis time. Studies of related genes in wheat link the family to seasonality.
