BOR1 — Brassica oleracea var. botrytis

Summary

BoBOR1, on cauliflower chromosome 3, 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, and cellular response to boron levels, as well as detection of nutrient and syngamy. It localises to the lateral plasma membrane, endosome, vacuole, cytoplasm, and sexine. BoBOR1 is associated with 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. Studies of related genes in other species connect the family to boron transport, plant growth, boron deficiency tolerance, boron tolerance, water retention, and disease resistance.
