TRAESCS2A02G187800 — triticum aestivum

Summary

TaBEH1 (TRAESCS2A02G187800) on wheat chromosome 2A encodes a BZR/BES1 family protein with a BES1_N domain and is annotated with transcription regulator activity, sequence-specific DNA binding, and multiple enzyme activities including phosphatidylethanolamine-sterol O-acyltransferase and sucrose synthase activity. The gene is associated with brassinosteroid content, regulation of vernalization response, positive regulation of ethylene biosynthesis, sterol breakdown, and jasmonic acid/ethylene-dependent systemic resistance. TaBEH1 has been linked to traits including root system morphology, leaf area, inflorescence length, fruit set, seed coat morphology, panicle number, total soluble sugar content, hydrogen peroxide content, nitrogen sensitivity, and bacterial disease response. It localizes to the chloroplast thylakoid, mitochondrial outer membrane, and PP2A complex, and participates in pathways including IAA efflux and GDP-L-fucose biosynthesis. Studies of related genes in other species connect the family to plant height, grain size, heading date, and sheath blight resistance.
