Salinity and osmotic stress-regulated proteins in cowpea Rhizobium 4a (peanut isolate)

Abstract

The effect of salinity and osmotic stress on protein synthesis was studied in cowpea Rhizobium 4a. Osmotic component of salinity stress has been shown to induce ten proteins in a salt tolerant/osmosensitive cowpea Rhizobium. 4a (groundnut isolate). Of these seven polypeptides were induced only by salt/osmotic stress while two were induced by heat shock. The results demonstrate a commonality as well as stress specificity of protein synthesis regulation.
