Two asian jumbo phages, Ï•RSL2 and Ï•RSF1, infect Ralstonia solanacearum and show common features of Ï•KZ-related phages.

Jumbo phages infecting Ralstonia solanacearum were isolated in Thailand (Ï•RSL2) and Japan (Ï•RSF1). They were similar regarding virion morphology, genomic arrangement, and host range. Phylogenetic and proteomic tree analyses demonstrate that the Ï•RSL2 and Ï•RSF1 belong to a group of evolutionary related phages, including Pseudomonas phages Ï•KZ, 201Ï•2-1 and all previously described Ï•KZ-related phages.
