BVRB_4G085230 — Beta vulgaris subsp. vulgaris

Summary

BvBEH1 (BVRB_4G085230) on sugar beet chromosome 4 encodes a protein with a BZR and BES1_N domain and transcription regulator activity with sequence-specific DNA binding activity. In sugar beet, the gene is associated with taproot diameter and sucrose accumulation, and with sterol breakdown, positive regulation of ethylene biosynthesis, regulation of vernalization response, and jasmonic acid/ethylene-dependent systemic resistance. It is linked to brassinosteroid content, cold and chilling tolerance, photosynthesis, photoprotection, flowering time, seed number, pollen viability and germination, cadmium resistance, autophagy, and stress tolerance. The gene is also connected to root system morphology, leaf area, stomatal process traits, gravity response, light quality response, and total soluble sugar content. Studies of related genes in other species link BZR/BES1 homologs to chloroplast biogenesis, defense responses, drought tolerance, starch biosynthesis, and carbon partitioning.
