BEH1 — Beta vulgaris subsp. vulgaris

Summary

BvBEH1 (BvBZR1, BvBES1) on sugar beet chromosome 1 encodes a BZR/BES1 family transcription regulator with a BES1_N domain. The gene is associated with taproot diameter and sucrose accumulation in this species, and with sterol breakdown, positive regulation of ethylene biosynthesis, regulation of the vernalization response, and jasmonic acid/ethylene-dependent systemic resistance. It is linked to brassinosteroid-regulated transcription pathways, gibberellin signaling, and regulation of seed size. Associations also include cold and chilling tolerance, photosynthesis, photoprotection, flowering time, seed number, pollen viability, cadmium resistance, and autophagy. The gene is connected to tuberous root diameter, root system morphology, leaf area, stomatal traits, and responses to light quality, gravity, and nutrients. Studies of related genes in other species link the BZR/BES family to fruit ripening, wood formation, drought tolerance, defense responses, and chloroplast biogenesis.
