BEH1 — Daucus carota subsp. sativus

Summary

DCAR_019605 (DcBEH1) on carrot chromosome 5 encodes a protein with BES1_N and BZR domains. The gene is associated with transcription regulator activity, sequence-specific DNA binding, and multiple acyltransferase activities. DcBEH1 has been linked to brassinosteroid-regulated transcription pathways, including BZR/BES phosphorylation and dephosphorylation, and interactions with BIM1 and 14-3-3 proteins. It is associated with diverse biological processes such as sterol breakdown, positive regulation of ethylene biosynthesis, jasmonic acid-mediated signaling, and vernalization response. Associations with agronomically relevant traits include root system morphology, total soluble sugar content, fruit quality, leaf area, inflorescence length, brassinosteroid content, and responses to light quality, nitrogen, and sulfur. The gene is also linked to cold tolerance, photosynthesis, flowering time, seed number, and cadmium resistance. Studies of related genes in other species connect the family to taproot diameter, sucrose accumulation, fruit ripening, and wood formation.
