High salinity is an environmental factor that
inhibits plant growth and development, leading to large
losses in crop yields. We report here that mutations in SIZ1
or PHO2, which cause more accumulation of phosphate
compared with the wild type, enhance tolerance to salt
stress. The siz1 and pho2 mutations reduce the uptake and
accumulation of Na+. These mutations are also able to suppress
the Na+ hypersensitivity of the sos3-1 mutant, and
genetic analyses suggest that SIZ1 and SOS3 or PHO2 and
SOS3 have an additive eVect on the response to salt stress.
Furthermore, the siz1 mutation cannot suppress the Li+
hypersensitivity of the sos3-1 mutant. These results indicate
that the phosphate-accumulating mutants siz1 and pho2
reduce the uptake and accumulation of Na+, leading to
enhanced salt tolerance, and that, genetically, SIZ1 and
PHO2 are likely independent of SOS3-dependent salt signaling
