The recombinant elicitor protein was expressed in Escherichia coli using pET 28a expression vector and induced necrosis in the leaves of tobacco. ...These results not only recommend the putative utilization of PeBb1 elicitor protein in future biological pest control strategies against phloem feeding insect pests such as M. persicae, but also help in better comprehension of the mechanisms through which beneficial fungi trigger the induced plant resistance....
