SOS1, a Genetic Locus Essential for Salt Tolerance and Potassium Acquisition

To begin to determine which genes are essential for salt tolerance in
higher plants, we identified four salt-hypersensitive mutants of
Arabidopsis by using a root-bending assay on NaCl-containing agar plates.
These mutants (sos1-1, sos1-2, sos1-3, and sos1-4) are allelic to each
other and were caused by single recessive nuclear mutations. The SOS1 gene
was mapped to chromosome 2 at 29.5 [plusmn] 6.1 centimorgans. The mutants
showed no phenotypic changes except that their growth was >20 times more
sensitive to inhibition by NaCl. Salt hypersensitivity is a basic cellular
trait exhibited by the mutants at all developmental stages. The sos1
mutants are specifically hypersensitive to Na+ and Li+. The mutants were
unable to grow on media containing low levels (below ~1 mM) of potassium.
Uptake experiments using 86Rb showed that sos1 mutants are defective in
high-affinity potassium uptake. sos1 plants became deficient in potassium
when treated with NaCl. The results demonstrate that potassium acquisition
is a critical process for salt tolerance in glycophytic plants.
