BEH1 — Triticum aestivum

Summary

TaBEH1 (TRAESCS2B02G219300) on wheat chromosome 2B encodes a BZR/BES1 family protein with transcription regulator activity and sequence-specific DNA binding. It is associated with brassinosteroid content, seminal root length, gravity response, inflorescence length, leaf area, fruit set, seed coat morphology, and total soluble sugar content. The gene is linked to regulation of vernalization response, positive regulation of ethylene biosynthesis, sterol breakdown, and jasmonic acid/ethylene-dependent systemic resistance. It localizes to the chloroplast thylakoid, mitochondrial outer membrane, and PP2A complex. Studies of related genes in other species connect the family to plant height, grain size, heading date, sheath blight resistance, and salinity tolerance, and to chloroplast biogenesis, cold tolerance, and leaf morphology.
