| Comment | The gene encodes for a plasma membrane localized efflux transporter of boron and is a homolog of Arabidopsis BOR1 gene (AT2G47160). The mRNA levels were expressed 10 times more in roots relative to the shoots (leaf). Accumulation increases in boron deficient growth medium. The slower growth and increased sensitivity to boron deficiency was observed for mutant forms of the gene (tos17 insertion lines). The transporter is also involved in efficient loading of boron in the xylem sap. It shows transient localization of the protein in root stele followed by exodermis and back to stele when the plants were treated with normal supply of boron on day 0, followed by boron deficient growth medium for 3 days and 6 days.
