Proc Natl Acad Sci USA 1998, 95:1325-1330. The function of pathogen avirulence genes has been enigmatic. Several examples among plant bacterial pathogens have indicated that avirulence gene mutants have decreased virulence. This paper describes two dspEF genes in the apple fireblight pathogen Erwinia that encode factors necessary for virulence. When transferred and expressed in Pseudomonas syringae, however, they function as avirulence genes and induce defence responses in specific resistant lines of soybean. Avirulence genes with high sequence similarity are also identified in P. syringae and these genes can complement dspEF mutants in Erwinia. These data provide strong support for the view that avirulence genes encode virulence factors for which host genotypes have evolved specific surveillance mechanisms. Furthermore, they suggest the intriguing possibility of isolating resistance genes from soybean which have the appropriate specificity to protect apple (for which no fireblight R genes are known) from this disease.
