AT1G75080 — Arabidopsis thaliana

Summary

AT1G75080 (BZR1) in Arabidopsis thaliana encodes a protein with transcription regulator activity and sequence-specific DNA binding, belonging to the BZR/BES1_N protein family. The gene is associated with sterol breakdown, polyprenol biosynthesis, and anthocyanin accumulation under low nitrogen stress. BZR1 is linked to floral transition, primary growth, and positive regulation of ethylene biosynthesis. Phenotypic associations include cold and chilling tolerance, photosynthesis, photoprotection, seed number, pollen viability and germination, cadmium resistance, and flowering time. The gene is also connected to traits such as drought recovery, root system morphology, leaf area, seed volume and shape, fruit quality, and gravity response. Studies of related genes in other species link the family to xylem differentiation, wood formation, disease resistance, nitrogen starvation response, and sucrose accumulation.
