BOR1 — Brassica oleracea var. botrytis

Summary

BoBOR1, located on cauliflower chromosome 4, encodes a protein with borate efflux transmembrane transporter activity and borate channel activity, belonging to the HCO3_transpt_euk family. This gene is associated with borate membrane transport, response to boron, and cellular response to boron levels. It is linked to boron toxicity tolerance, boron translocation, excess boron tolerance, boron homeostasis, fertility under boron limitation, seed yield, female fertility, root elongation, leaf growth, and seedling growth under low boron and high nitrate conditions. BoBOR1 is associated with nitrate response and boron concentration in leaves. The encoded protein localises to the lateral plasma membrane, endosome, vacuole, cytoplasm, and sexine. Studies of related genes in other species link the family to boron transport, plant growth, boron deficiency tolerance, and disease resistance.
