BEH1 — Daucus carota subsp. sativus

Summary

DCAR_021029 (DcBEH1) on carrot chromosome 6 encodes a protein with a BZR domain and a BES1_N domain, and is annotated with transcription regulator activity and sequence-specific double-stranded DNA binding activity. The gene is associated with BZR/BES-regulated transcription and phosphorylation-dependent nuclear-cytosolic shuttling pathways. DcBEH1 is linked to sterol breakdown, positive regulation of ethylene biosynthesis, jasmonic acid/ethylene-dependent systemic resistance, and regulation of the vernalization response. Associations with traits include root system morphology, total soluble sugar content, fruit quality, leaf area, inflorescence length, adventitious root number, brassinosteroid content, and responses to light quality, nitrogen, and sulfur. The gene is also linked to cold tolerance, chilling tolerance, photosynthesis, flowering time, seed number, pollen viability, and cadmium resistance. Related genes in other species connect the family to taproot diameter, sucrose accumulation, fruit ripening, and wood formation.
