BEH1 — Beta vulgaris subsp. vulgaris

Summary

BvBEH1 (BVRB_8G201060) on sugar beet chromosome Bvchr8_un.sca006 encodes a BZR/BES1 family protein with a BES1_N domain. It is annotated with transcription regulator activity and sequence-specific DNA binding, and is associated with sterol breakdown, positive regulation of ethylene biosynthesis, and regulation of the vernalization response. In sugar beet, the gene has been linked to taproot diameter and sucrose accumulation. Broader associations include cold and chilling tolerance, photosynthesis, photoprotection, flowering time, seed number, pollen viability and germination, cadmium resistance, and autophagy. The gene is also connected to traits such as root system morphology, leaf area, fruit quality, brassinosteroid content, and responses to gravity, light quality, and sulfur. Studies of related genes in other species link it to carbon partitioning, chloroplast biogenesis, and defense responses.
