VRN1 — Brachypodium distachyon

Summary

BRADI_4G06867V3 (VRN1, also known as BdMADS20) encodes a MADS-box transcription factor containing a K-box domain and MEF2-like domain, with RNA polymerase II transcription regulatory region sequence-specific DNA binding activity and protein dimerization activity. The gene is associated with the vernalization response, including both its upregulation and downregulation, as well as cold acclimation, regulation of photoperiodism and flowering, flower development, carpel development, floral meristem determinacy, organogenesis, cell differentiation, and habituation and memory processes. It is linked to anthesis time and localises to the nucleus. Related genes in other species connect the gene family to seasonality.
