Induction of Systemic Immunization: Another Approach for Plant Disease Control

Abstract

Vaccination of plants has been suggested as an alternative to conventional pesticides for disease control. Although plants have no antibody-generating system, it is generally believed that plants exposed to attenuated pathogens, hypo virulent pathogens or (non-pathogens,) become more resistant to compatible than plants that have not been exposed to such biotic stimuli. Disease resistance can also be induced by treatment with compounds of cell wall components and some chemicals. The immunization of plants might involve the activation of multiple resistance mechanisms against pathogens. The mechanism of this induced resistance has at least two components; the chemical agents, including phytoalexins, that accumulate around the site of infection to inhibit development of pathogens, and the signal that commits cells removed from site of an inducing inoculation to respond rapidly when challenged. Following the acceptance of the concept of this immunization system. The technology for immunization of plants using is needs to be developed for the control of some diseases under field conditions.
