BEH1 — Beta vulgaris subsp. vulgaris

Summary

BvBEH1 (BVRB_6G137710) on sugar beet chromosome 6 encodes a protein with a BZR and BES1_N domain and is associated with sequence-specific DNA binding and transcription regulator activity. In sugar beet, the gene is associated with taproot diameter and sucrose accumulation. It is also associated with sterol breakdown, positive regulation of ethylene biosynthesis, regulation of vernalization response, and jasmonic acid/ethylene-dependent systemic resistance. The product is associated with phytochrome binding, MAPKK activity, and various histone methylase and demethylase activities. Localization evidence connects it to the Toc complex, chloroplast thylakoid, PP2A complex, and mitochondrial membranes. Studies of related genes in other species link the family to brassinosteroid signaling, seed size regulation, stress tolerance, fruit ripening, xylem differentiation, and wood formation.
