Plant immune responses are triggered by pattern recognition receptors that detect conserved pathogen-associated molecular patterns (PAMPs) or by resistance (R) proteins recognizing isolate-specific pathogen effectors. We show that in barley, intracellular mildew A (MLA) R proteins function in the nucleus to confer resistance against the powdery mildew fungus. Recognition of the fungal avirulenc...
A temperature-sensitive (ts) mutant, tsG1, has been isolated from the CVS (Challenge Virus Standard) strain of rabies virus. The ts mutation affects the glycoprotein (G protein); it consists of an amino acid substitution (leucine to phenylalanine) at position 132. tsG1 exhibits a slightly reduced pathogenicity when administered via the intracerebral route and complete avirulence after intramusc...
The virulence of Candida albicans strain SC5413 and two isogenic derivatives have been investigated in a rat model of oropharyngeal candidiasis. The results demonstrate that both mutant strains are avirulent in this animal model while the parental strain readily initiates infection. Avirulence is not related to altered growth characteristics or the inability of the strains to undergo yeast-to-h...
AvrPtoB is a type III effector protein from Pseudomonas syringae pv. tomato that physically interacts with the tomato Pto kinase and, depending on the host genotype, either elicits or suppresses programmed cell death associated with plant immunity. We reported previously that avrPtoB-related sequences are present in diverse gram-negative phytopathogenic bacteria. Here we describe characterizati...
Plant disease resistance genes trigger defence mechanisms upon recognition of pathogen compatibility factors, which are encoded by avirulence genes. Isolation of the barley powdery mildew resistance gene Mla opens the door to understanding the extensive allelic diversity of this locus. Completion of the Arabidopsis genome sequence enables the analysis of the complete set of R-gene homologues in...
