Plant Pathology: Infection Process: Plant Defenses: Genetics of Resistance
... of resistance is usually referred to as gene-for-gene resistance, because in most cases it requires the presence of both a race-specific avirulence (avr) gene in the pathogen and one or more ... races harbouring the elicitor. The elicitor is generally the protein that is encoded by the avirulence gene, however in some plant-pathogen interactions the elicitor has been found to be the product ...

Gene Specific Interactions
... Gene Specific Interactions Gene Specific Interactions Resistance is only induced when a plant cultivar in possession of a specific resistance (R) gene recognises a pathogen race that contains the corresponding avirulence (avr) gene (a). The absense of either the avirulence gene (b), the resistance gene (c) or ...
