VRN3 — Triticum aestivum

Summary

TRAESCS2D02G345700 (VRN3) on bread wheat chromosome 2D encodes a phosphatidylethanolamine-binding protein (PEBP family) with annotated mRNA regulatory element binding translation repressor activity, protein N-GlcNAc transferase activity, peptide-O-fucosyltransferase activity, phosphatidylethanolamine binding, lipid binding, sequence-specific DNA binding, and DNA-binding transcription factor activity. The gene is associated with upregulation of vernalization response and long-day photoperiodism, flowering, floral whorl development, meristem determinacy, secondary shoot formation, response to short-day, strigolactone response, temperature compensation of the circadian clock, and red light signaling. It has been linked to photoperiod sensitivity, flowering time, spikelet floret size, inflorescence development, stem length, vegetative vigor, spot blotch, drought stress, water loss, stomatal traits, and shoot branching. Studies of related genes in other species connect the family to photoperiodic flowering, floral transition, inflorescence architecture, seed yield, and drought escape response.
