ID 86354
Name BOR1 (GENE SYMBOL)
Synonyms (2)
GRAMENE GENEGR:0101271
Type Gene
Species Oryza sativa (Oryza sativa) [ GR_tax:013681 ]
Germplasm
Description 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.
