Erwinia chrysanthemi harpinEch: an elicitor of the hypersensitive response that contributes to soft-rot pathogenesis.


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. The hrpNEch gene was identified in a collection of cosmids carrying E. chrysanthemi hrp genes by its hybridization with the Erwinia amylovora hrpNEa gene. hrpNEch… (More)
