ϕRP15 infects Ralstonia solanacearum, the causative agent of bacterial wilt disease. Genes encoded by ϕRP15 show the highest sequence similarity to those of Delftia phage ϕW-14. ϕRP15 with ϕW-14 form a clade closely related to the genus Viunalikevirus by phylogenetic analyses. ϕRP15 encodes 17 tRNAs corresponding to minor codons of the host. ϕRP15 particles show unique star-like protrusions stemming from the baseplate.
