BOR1 — Brassica napus

Summary

BnBOR1 (DARMORV10_A04P34810.1) on chromosome A04 of oilseed rape (Brassica napus) encodes a borate efflux transmembrane transporter with borate channel activity, belonging to the HCO3_transpt_euk family. The gene is associated with borate membrane transport, response to boron, cellular response to boron levels, detection of nutrient, organogenesis, inflorescence development, homeostasis, and response to thirst. It has been linked to boron toxicity tolerance, boron translocation, fertility under boron limitation, root elongation, excess boron tolerance, seedling growth under low boron and high nitrate conditions, boron concentration in leaves, nitrate response, leaf growth, boron uptake, seed yield, boron homeostasis, and female fertility. The encoded protein localizes to the lateral plasma membrane, endosome, vacuole, plasmalemma, cytoplasm, and sexine. Studies of related genes in other species link the family to boron transport, plant growth, boron deficiency tolerance, boron tolerance, water retention, and disease resistance.
