Abstract

Complete genome sequence of a broad-host-range lytic Dickeya spp. bacteriophage φD5.

Abstract

Little is known about lytic bacteriophages infecting plant-pathogenic Dickeya spp. These bacteria cause economically significant losses in arable crops and ornamental plant production worldwide. At present, there is no effective control of diseases caused by Dickeya spp. A novel bacteriophage, φD5, belonging to the family Myoviridae, order Caudovirales, that could be used to control these bacteria was isolated previously. This report provides information on its characterization. The φD5 genome consists of 155,346-bp-length double-stranded DNA with a GC content of 49.7% and is predicted to have 196 open reading frames (ORFs) with an average length of 711 nucleotides each. The ORFs were classified into functional groups, including phage structure, packaging, DNA metabolism, regulation, and additional functions. The phage lifestyle predicted from PHACTS indicated that φD5 may be a lytic phage and therefore can efficiently kill plant-pathogenic Dickeya spp.
