Soil salinity is a major abiotic stress in reducing plant growth and agricultural productivity.In higher plants,14-3-3 proteins are phosphoserine-binding proteins that regulate the activity of a wide array of targets via protein-protein interaction and play a key role in abiotic stress.We report here that CaMV 35S promoter driven overexpression of the TFT7 gene,one of tomato 14-3-3 proteins,improves plant salt tolerance in Arabidopsis thaliana.In response to salt stress,transgenic plants overexpressing TFT7 improved germination rate,dry mass,total chlorophyll concentration and root length.
