BOR1 — Triticum aestivum

Summary

TRAESCS5A02G085200, designated TaBOR1 on bread wheat chromosome 5A, encodes a protein with bicarbonate transporter-like domains and is annotated with borate efflux transmembrane transporter activity. The gene is associated with borate membrane transport, cellular response to boron levels, and anion transmembrane transport. TaBOR1 has been linked to boron sensitivity, boron toxicity tolerance, boron efficiency, and seed yield, as well as to root development, embryo development, and response to abscisic acid. It is also connected to floral organ identity, stomatal opening, and abscisic acid sensitivity. The encoded protein localises to the plasma membrane, endosome, vacuole, mitochondria, cytosol, and nucleus. Studies of related genes in other species link the BOR family to boron transport, boron deficiency tolerance, and reproductive development.
