Harpin, elicitor of the hypersensitive response produced by the plant pathogen Erwinia amylovora
Zhong-Min Wei,Ron Laby,Cathy H. Zumoff,David W. Bauer,Sheng Yang He,Alan Collmer,Steven V. Beer +6 more
TL;DR: A proteinaceous elicitor of the plant defense reaction known as the hypersensitive response was isolated from Erwinia amylovora, the bacterium that causes fire blight of pear, apple, and other rosaceous plants.
Journal ArticleDOI
Expression of the Pseudomonas syringae avirulence protein AvrB in plant cells alleviates its dependence on the hypersensitive response and pathogenicity (Hrp) secretion system in eliciting genotype-specific hypersensitive cell death.
TL;DR: Both stable and transient expression of avrB in Arabidopsis resulted in RPM1-dependent necrosis, and the only demonstrable site of action for AvrB was inside plant cells, suggesting that the site of Avr B action is not in the bacterial cell or plant apoplast.
Journal ArticleDOI
Harpin induces disease resistance in Arabidopsis through the systemic acquired resistance pathway mediated by salicylic acid and the NIM1 gene
TL;DR: Harpin elicits disease resistance through the NIM1-mediated SAR signal transduction pathway in an SA-dependent fashion and the site of action of harpin in the SAR regulatory pathway is upstream of SA.
Journal ArticleDOI
Erwinia chrysanthemi hrp genes and their involvement in soft rot pathogenesis and elicitation of the hypersensitive response.
TL;DR: The hrp mutations reduced the ability of both AC4150 and CUCPB5006 to incite successful infections in witloof chicory leaves and abolished the ability to cause any necrosis in tobacco leaves unless complemented with pCPP2030.
Journal ArticleDOI
Erwinia chrysanthemi HarpinEch: an elicitor of the hypersensitive response that contributes to soft-rot pathogenesis
TL;DR: Mutants of the soft-rot pathogen Erwinia chrysanthemi EC16 that are deficient in the production of the pectate lyase isozymes PelABCE can elicit the hypersensitive response (HR) in tobacco leaves and the hrpNEch gene appears to be in a monocistronic operon.
