Erwinia amylovora, the causal agent of fire blight disease of apples and pears, is one of the most important plant bacterial pathogens with worldwide economic significance. Recent reports on the complete or draft genome sequences of four species in the genus Erwinia, including E. amylovora, E. pyrifoliae, E. tasmaniensis, and E. billingiae, have provided us near complete genetic information abo...

Fire blight caused by the Gram-negative bacterium Erwinia amylovora can be controlled by antagonistic microorganisms. We characterized epiphytic bacteria isolated from healthy apple and pear trees in Australia, named Erwinia tasmaniensis, and the epiphytic bacterium Erwinia billingiae from England for physiological properties, interaction with plants and interference with growth of E. amylovora...

Here, we present the genome of a strain of Erwinia amylovora, the fire blight pathogen, with pathogenicity restricted to Rubus spp. Comparative genomics of ATCC BAA-2158 with E. amylovora strains from non-Rubus hosts identified significant genetic differences but support the inclusion of this strain within the species E. amylovora.

Lytic bacteriophages are in development as biological control agents for the prevention of fire blight disease caused by Erwinia amylovora. Temperate phages should be excluded as biologicals since lysogeny produces the dual risks of host resistance to phage attack and the transduction of virulence determinants between bacteria. The extent of lysogeny was estimated in wild populations of E. amyl...

Plant-associated Erwinia include pathogenic and nonpathogenic species. We report the 5.6-Mb genome sequence of Erwinia billingiae OSU19-1, isolated from a canker on a pear tree inoculated with Erwinia amylovora. OSU19-1 and a closely related European isolate, E. billingiae Eb661(T), share many similarities including 40 kb of plasmid sequence.

Erwinia amylovora is the causal agent of fire blight, a devastating disease affecting some plants of the Rosaceae family. We isolated bacteriophages from samples collected from infected apple and pear trees along the Wasatch Front in Utah. We announce 19 high-quality complete genome sequences of E. amylovora bacteriophages.

The Erwinia amylovora rpoS gene, encoding the alternative sigma factor RpoS, has been cloned and characterized. Though highly sensitive to a number of environmental stresses, an E. amylovora rpoS mutant was not compromised in its ability to grow or cause disease symptoms within apple seedlings or in an overwintering model.

Thin sectioned cells of Erwinia amylovora revealed two electron-dense layers in their walls when fixed at 24 to 27 C and three when fixed at 4 C.

Erwinia amylovora is the causative agent of fire blight, a serious disease of some Rosaceae plants. The newly isolated bacteriophage PhiEaH2 is able to lyse E. amylovora in the laboratory and has reduced the occurrence of fire blight cases in field experiments. This study presents the sequenced complete genome and analysis of phage PhiEaH2.
