Recognition of the Bacterial Avirulence Protein AvrBs3 Occurs inside the Host Plant Cell
The molecular mechanism by which bacterial avirulence genes mediate recognition by resistant host plants has been enigmatic for more than a decade. In this paper we provide evidence that the Xanthomonas campestris pv. vesicatoria avirulence protein AvrBs3 is recognized inside the plant cell. Transient expression of avrBs3 in pepper leaves, using Agrobacterium tumefaciens for gene delivery, resu...
متن کاملBacterial avirulence genes.
Although more than 30 bacterial avirulence genes have been cloned and characterized, the function of the gene products in the elictitation of resistance is unknown in all cases but one. The product of avrD from Pseudomonas syringae pv. glycinea likely functions indirectly to elicit resistance in soybean, that is, evidence suggests the gene product is an enzyme involved in elicitor production. I...
متن کاملProspects for understanding avirulence gene function.
Avirulence genes are originally defined by their negative impact on the ability of a pathogen to infect their host plant. Many avirulence genes are now known to represent a subset of virulence factors involved in the mediation of the host-pathogen interaction. Characterization of avirulence genes has revealed that they encode an amazing assortment of proteins and belong to several gene families...
متن کاملIdentification of Rust Fungi Avirulence Elicitors
Rust fungi (Basidiomycetes of the order Uredinales) are obligate biotrophs that grow and reproduce only in living plant tissue. There are on the order of 5000 or more species of rust fungi that collectively cause disease on most crops, ornamentals, and many other plants. For example, rusts caused by Puccinia species are some of the most important diseases of wheat and other small grain crops wo...
متن کاملCOMMENTARY: Why do pathogens carry avirulence genes?
In the gene-for-gene hypothesis, Flor [19] proposed the existence of avirulence alleles of virulence genes, and that the virulence genes actively conditioned cultivar-specific virulence on hosts. Yet cultivar-specific virulence genes have not been found, and many of the avirulence (ar) genes cloned to date (over 40) do not appear to condition pathogenicity in general, virulence or anything els...
