BOR1 — Triticum aestivum

Summary

TRAESCS5D02G097600, designated TaBOR1 on bread wheat chromosome 5D, encodes an inorganic anion exchanger with transmembrane transporter activity, belonging to the HCO3_transpt_euk family. The protein localises to the plasmalemma and is associated with monoatomic anion transport, monoatomic ion homeostasis, and response to boron. In wheat, TaBOR1.1 has been linked to boron deficiency tolerance. The gene is also associated with boron sensitivity, boron toxicity tolerance, grain yield per plant, harvest index, test weight, grain iron and zinc content, grain protein content, stand establishment, plant vigor, net photosynthetic rate, quantum yield, drought sensitivity, root and lateral root number, floral organ identity, meristem identity, stem elongation, starch and sugar content, proline content, leaf and seed coat color, and resistance to powdery mildew.
