Gene Details:

Functional Descriptions:

  • Rice shaker potassium channel OsKAT1 confers tolerance to salinity stress on yeast and rice cells.
  • By the expression of OsKAT1, the K(+) contents of salt-stressed G19 cells increased during the exponential growth phase.
  • These results suggest that OsKAT1 is involved in salt tolerance of rice in cooperation with other K(+) channels by participating in maintenance of cytosolic cation homeostasis during salt stress and thus protects cells from Na(+).
  • We found that expression of a cDNA clone, encoding the rice homolog of Shaker family K(+) channel KAT1 (OsKAT1), suppressed the salt-sensitive phenotype of yeast strain G19 (Deltaena1-4), which lacks a major component of Na(+) efflux.
  • Rice cells overexpressing OsKAT1 also showed enhanced salt tolerance and increased cellular K(+) content.
  • These functions of OsKAT1 are likely to be common among Shaker K(+) channels because OsAKT1 and Arabidopsis (Arabidopsis thaliana) KAT1 were able to complement the salt-sensitive phenotype of G19 as well as OsKAT1.
  • In addition, the real-time PCR results revealed that OsAKTs and OsKATs are induced by salt stress in root and shoot tissues of rice cultivars, and OsKAT1 was identified as a key gene involved in the rice response to salt stress.
