BEH1 — Daucus carota subsp. sativus

Summary

DCAR_017224 (DcBEH1) on carrot chromosome 5 encodes a BZR/BES1 family protein with transcription regulator activity and sequence-specific DNA binding. It is associated with brassinosteroid signaling pathways, including BZR/BES-regulated transcription and phosphorylation-dependent nuclear-cytosolic shuttling. The gene has been linked to diverse traits such as root system morphology, fruit set, inflorescence length, leaf area, stomatal process-related traits, brassinosteroid content, and responses to light quality, gravity, and sulfur. It is also connected to cold tolerance, photosynthesis, chilling tolerance, seed number, pollen viability, flowering time, and cadmium resistance. Related genes in other species have been linked to defense responses, chloroplast biogenesis, starch biosynthesis, ethylene production, and viral resistance, as well as fruit ripening, taproot diameter, sucrose accumulation, and xylem differentiation.
