The plant cytoskeleton, including microtubules and microfilaments, is one of the important factors in determining the polarity of cell division and growth, as well as the interaction of plants with invading pathogens. In defense responses of wheat against the stripe rust (Puccinia striiformis f. sp. tritici) infection, hypersensitive response is the most crucial event to prevent the spread of p...

A cosmid clone isolated from a genomic library of Pseudomonas syringae pv. syringae 61 restored to all Tn5 mutants of this strain studied the ability to elicit the hypersensitive response (HR) in tobacco. Cosmid pHIR11 also enabled Escherichia coli TB1 to elicit an HR-like reaction when high levels of inoculum (10(9) cells per ml) were infiltrated into tobacco leaves. The cosmid, which contains...

A nearly ubiquitous feature of plant-pathogen interactions is host cell death. In its most recognizable form, host cell death is manifested as the rapid collapse of tissue, termed the hypersensitive response (HR). This response accompanies “incompatible interactions” and leads to disease resistance. As detailed below, the HR is programmed genetically in the plant and is a consequence of new hos...

Stripe rust [caused by Puccinia striiformis Westend. f. sp. tritici Eriks. (Pst)] is a destructive disease of wheat (Triticum aestivum L.) worldwide. Genetic resistance is the preferred method for control and the Yr5 gene, originally identified in Triticum spelta var. album, represents a major resistance (R) gene that confers all-stage resistance to all currently known races of Pst in the Unite...

Tomato Cf genes encode membrane-bound proteins with extracellular leucine-rich repeats, and confer resistance to the fungal tomato pathogen Cladosporium fulvum, and a hypersensitive response (HR) to C. fulvum-derived race-specific elicitors. Several Cf genes, including Cf-4 and Cf-9, are members of the highly homologous Hcr9 (homologues of C. fulvumresistance gene Cf-9) gene family. Hcr9s evolv...

Genetic studies have identified a number of components of signal transduction pathways leading to plant disease resistance and the accompanying hypersensitive response (HR) following detection of pathogens by plant resistance (R) genes. In Arabidopsis, the majority of R proteins so far characterized belong to a plant superfamily that have a central nucleotide-binding site and C-terminal leucine...
