Genomic Characterization of Ralstonia solanacearum Phage φRSB1, a T7-Like Wide-Host-Range Phage

摘要

φRSΒ1 is a wide-host-range, T7-like bacteriophage that infects and efficiently lyses the phytopathogenic bacterium Ralstonia solanacearum. The φRSB1 genome comprises 43,079 bp of double-stranded DNA (61.7% G+C) with 325-bp terminal repeats and contains 47 open reading frames. Strong activity of tandem early promoters and wide specificity of phage promoters of φRSB1 were demonstrated.
