Plants pass the salt

Trends Plant Sci. 2003 May;8(5):200-1. doi: 10.1016/S1360-1385(03)00059-1.


Recently, overexpression of the plasma membrane Na(+)/H(+) antiporter SOS1 was shown to increase salt tolerance of Arabidopsis and revealed that levels of SOS1 mRNA are post-transcriptionally regulated by salt stress. In addition to demonstrating a novel approach to engineer salt-tolerant crops, the results provide the first glimpse of a previously unknown mechanism used by plants to regulate gene expression in response to salt stress.
