Plant necrotrophic Dickeya spp. are among the top ten most devastating bacterial plant pathogens able to infect a number of different plant species worldwide including economically important crops. Little is known of the lytic bacteriophages infecting Dickeya spp. A broad host lytic bacteriophage ϕD3 belonging to the family Myoviridae and order Caudovirales has been isolated in our previous study. This report provides detailed information of its annotated genome, structural proteome and phylogenetic relationships with known lytic bacteriophages infecting species of the Enterobacteriaceae family.
