Updated FTP location. Jumbo phages ϕRP31/ϕRP12 infecting Ralstonia solanacearum were isolated in Thailand. Virion proteins of ϕRP31 separated by SDS-PAGE were visualized with Coomassie Brilliant Blue. The protein bands were excised from the gel, digested with trypsin, and analyzed by liquid chromatography-tandem mass spectrometry (LTQ Orbitrap XL). Assignment of tandem mass spectrometry data to tryptic peptides encoded by phage open reading frames was completed using an established procedure (Ahmad et al., 2014). Based on these genomic similarities, proteomic tree and gene phylogenies, we propose that ϕRP12 and ϕRP31 are new members of the group of ϕKZ-related phages.
