The Problems of Specific Phytoimmunity

The Problems of Specific Phytoimmunity Recent studies established that the specificity of phytoimmunity is shaped at the initial stages of genic interactions between a pathogen and its plant host. While elicitors, the products of pathogen avirulence genes (avr-genes), have been already investigated in great detail, there are few studies on the products of plant resistance genes (R-genes) recognizing these elicitors. This review deals with examples of nonspecific and specific elicitors of some R-genes as well as the systems that transduce the elicited signals to the plant genome and evoke immune responses in the plant cells. Several types of immunosuppressors characteristic of pathogens are considered. The molecular-genetic studies of the relations between the pathogens and their plant hosts supplement the already existing arsenal for plant protection with new technologies, such as the genetically engineered plant resistance and the resistance induced by biogenic elicitors. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals

Abstract

Recent studies established that the specificity of phytoimmunity is shaped at the initial stages of genic interactions between a pathogen and its plant host. While elicitors, the products of pathogen avirulence genes (avr-genes), have been already investigated in great detail, there are few studies on the products of plant resistance genes (R-genes) recognizing these elicitors. This review deals with examples of nonspecific and specific elicitors of some R-genes as well as the systems that transduce the elicited signals to the plant genome and evoke immune responses in the plant cells. Several types of immunosuppressors characteristic of pathogens are considered. The molecular-genetic studies of the relations between the pathogens and their plant hosts supplement the already existing arsenal for plant protection with new technologies, such as the genetically engineered plant resistance and the resistance induced by biogenic elicitors.
