AT3G50750 — Arabidopsis thaliana

Summary

AT3G50750 (BEH1, BES1/BZR1 homolog 1) in Arabidopsis thaliana encodes a BZR/BES1_N domain-containing protein with transcription regulator activity and sequence-specific DNA binding. This gene is associated with brassinosteroid signaling pathways, including BZR/BES-regulated transcription and gibberellin signaling. BEH1 is linked to numerous traits including gravity response, female sterility, root system morphology, fruit set, inflorescence length, leaf area, seed coat morphology, floral organ number, brassinosteroid content, oleic acid content, and responses to light quality, sulfur, and nitrogen. It is also associated with phenotypes such as xylem differentiation, wood formation, cold tolerance, photosynthesis, flowering time, seed number, pollen viability, fruit ripening, and cadmium resistance. The gene localizes to various cellular compartments including the Toc complex, chloroplast thylakoid, and mitochondrial membranes. Studies of related genes in other species link the family to disease resistance, fruit traits, drought sensitivity, and nitrogen starvation response.
