Bacteriophages of Erwinia amylovora.
Fifty bacteriophage isolates of Erwinia amylovora, the causal agent of fire blight, were collected from sites in and around the Niagara region of southern Ontario and the Royal Botanical Gardens, Hamilton, Ontario. Forty-two phages survived the isolation, purification, and storage processes. The majority of the phages in the collection were isolated from the soil surrounding trees exhibiting fi...
متن کاملIsolation and characterization of five Erwinia amylovora bacteriophages and assessment of phage resistance in strains of Erwinia amylovora.
Phages able to infect the fire blight pathogen Erwinia amylovora were isolated from apple, pear, and raspberry tissues and from soil samples collected at sites displaying fire blight symptoms. Among a collection of 50 phage isolates, 5 distinct phages, including relatives of the previously described phages phiEa1 and phiEa7 and 3 novel phages named phiEa100, phiEa125, and phiEa116C, were identi...
متن کاملNRAMP genes function in Arabidopsis thaliana resistance to Erwinia chrysanthemi infection.
AtNRAMP3 and AtNRAMP4 are two Arabidopsis metal transporters sharing about 50% sequence identity with mouse NRAMP1. The NRAMP1/Slc11A1 metal ion transporter plays a crucial role in the innate immunity of animal macrophages targeted by intracellular bacterial pathogens. AtNRAMP3 and AtNRAMP4 localize to the vacuolar membrane. We found that AtNRAMP3 is upregulated in leaves challenged with the ba...
متن کاملAntagonistic action of harpin proteins: HrpWea from Erwinia amylovora suppresses HrpNea-induced cell death in Arabidopsis thaliana.
Harpins are proteins secreted by the type-three secretion system of phytopathogenic bacteria. They are known to induce a hypersensitive response (HR) in non-host plant leaf tissue. Erwinia amylovora, the fire blight pathogen of pear and apple trees, secretes two different harpins, HrpNea and HrpWea. In the present study, we showed that an Erwinia amylovora hrpWea mutant induces stronger electro...
متن کاملPhenotypic diversity of Erwinia amylovora in Bulgaria.
Fifty-one strains of Erwinia amylovora isolated from nine host plants in Bulgaria were characterized phenotypically and identified by the API 20E and BIOLOG system. The identification was confirmed by PCR amplification of a specific region of the plasmid pEA29 and the genome ams region. The phenotypic diversity of the strains was studied on the basis of their API 20E and BIOLOG metabolic profil...
