title: The Arabidopsis Gene zinc finger protein 3(ZFP3) Is Involved in Salt Stress and Osmotic Stress Response.
abstract: Plants are continuously challenged by various abiotic and biotic stresses. To tide over these adversities, plants evolved intricate regulatory networks to adapt these unfavorable environments. So far, many researchers have clarified the molecular and genetic pathways involved in regulation of stress responses. However, the mechanism through which these regulatory networks operate is largely unknown. In this study, we cloned a C2H2-type zinc finger protein gene ZFP3 from Arabidopsis thaliana and investigated its function in salt and osmotic stress response. Our results showed that the expression level of ZFP3 was highly suppressed by NaCl, mannitol and sucrose. Constitutive expression of ZFP3 enhanced tolerance of plants to salt and osmotic stress while the zfp3 mutant plants displays reduced tolerance in Arabidopsis. Gain- and Loss-of-function studies of ZFP3 showed that ZFP3 significantly changes proline accumulation and chlorophyll content. Furthermore, over-expression of ZFP3 induced the expressions of stress-related gene KIN1, RD22, RD29B and AtP5CS1. These results suggest that ZFP3 is involved in salt and osmotic stress response.
