The first complete genome sequence for a myoviridal bacteriophage, PhiEa21-4, infecting Erwinia amylovora, Erwinia pyrifoliae, and Pantoea agglomerans strains has been determined. The unique sequence of this terminally redundant, circularly permuted genome is 84,576 bp. The PhiEa21-4 genome has a GC content of 43.8% and contains 117 putative protein-coding(More)
Erwinia amylovora is the causative agent of fire blight, a very destructive disease of numerous members of the rosaceae. The primary route of infection for host species, including commercially grown apple and pear, is the newly opened blossom. Susceptibility of flowers to infection for only a few days creates narrow window for infection. Not surprisingly,(More)
Erwinia amylovora and E. pyrifoliae are the causative agents of fire blight and Asian pear blight, respectively. The pathogens are closely related, with overlapping host ranges. Data are unavailable on the current distribution of E. pyrifoliae and on the interaction between the two species when they are present together on the same host. In this study, a(More)
