NCBI Protein Information
HCO3- transporter family
NCBI Summary
Boron transporter. Protein accumulates in shoots and roots under conditions of boron deficiency and is degraded within several hours of restoring boron supply. Localized to the plasma membrane under B limitation, and to the cytoplasm after B application before degradation. Protein is transferred via the endosomes to the vacuole for degradation. Localized to the inner plasma membrane domain in the columella, lateral root cap, epidermis, and endodermis in the root tip region, and in the epidermis and endodermis in the elongation zone. Under high-boron is transported to the vacuole for degradation.

UniProt Comments
Efflux-type boron transporter for xylem loading, responsive of boron translocation from roots to shoots under boron limitation. Under boron excess, BOR1 is transferred from the plasma membrane via the endosomes to the vacuole for degradation. Boron is essential for maintaining the integrity of plants cell walls.
