The zinc finger transcription factor OXIDATIVE STRESS 2 (OXS2) was previously reported to be involved in oxidative stress tolerance and stress escape. Here we report that an Arabidopsis oxs2-1 mutant is also more sensitive to salt stress. Conversely, the overproduction of a C-terminal fragment of OXS2, the 'AT3' fragment, can enhance salt tolerance in Arabidopsis by upregulating the transcription of at least six salt-induced genes: COR15A, COR47, RD29B, KIN1, ACS2 and ACS6.
