AT4G36780 — Arabidopsis thaliana

Summary

AT4G36780, designated BEH2 (BES1/BZR1 homolog 2) on Arabidopsis thaliana chromosome 4, encodes a BZR family protein with a BES1_N domain. The gene product is associated with transcription regulator activity and sequence-specific DNA binding, and is linked to sterol breakdown, positive regulation of ethylene biosynthesis, regulation of the vernalization response, and jasmonic acid/ethylene-dependent systemic resistance. BEH2 is associated with brassinosteroid content, tiller bud dormancy, gravity response, fruit set, inflorescence length, leaf area, root system morphology, and female sterility. It is also linked to xylem differentiation, wood formation, photosynthesis, cold tolerance, chilling tolerance, seed number, pollen viability, flowering time, and cadmium resistance. Studies of related genes in other species link the family to disease resistance, nitrogen starvation response, fruit ripening traits, and drought sensitivity.
