A lytic Ralstonia solanacearum-infecting phage designated Ralstonia phage RsoP1IDN was isolated from soil in Indonesia. The phage has a linear double-stranded DNA genome of 41,135 bp with 413-bp terminal repeats, and contains 41 annotated open reading frames. The phage is most closely related to Ralstonia phage RSB1, but different from RSB1 mainly in containing a putative HNH homing endonuclease and having a narrower host range. Our phylogenetic and genomic analyses revealed that both phages RsoP1IDN and RSB1 belong to the genus Pradovirus or a new genus, and not Phikmvvirus as previously reported for phage RSB1. RsoP1IDN is the first sequenced and characterized R. solanacearum-infecting phage isolated from Indonesia in the proposed species Ralstonia virus RsoP1IDN.

Background: Engineering the seed microenvironment with embedded bacteriophages and Plant Growth Promoting Rhizobacteria (PGPR) shows promise for enhancing germination, mitigating biotic and abiotic stressors, and improving resilience under challenging environmental conditions. This study aimed to enhance potato seed germination and control bacterial wilt caused by Ralstonia solanacearum and salinity by using novel technology to encapsulate, preserve, and deliver phage therapy and rhizobacteria.
Results: Silk fibroin and trehalose biomaterial combined with the phage P-PSG11 and Pseudomonas lalkuanensis were applied to potato seeds.

Phages can successfully be used in vitro and in planta to biocontrol the phytopathogenic Ralstonia solanacearum bacterium-the causal agent of bacterial wilt disease. However, phage biocontrol outcomes are still variable, and it is unclear what causes this. In this study, we assessed the efficiency of four phages in controlled in vitro and in planta experiments in all one- and two-phage combinations.

Soilborne species complex (RSSC) pathogens disrupt microbial communities as they invade roots and fatally wilt plants. RSSC pathogens secrete antimicrobial toxins using a type VI secretion system (T6SS). To investigate how evolution and ecology have shaped the T6SS of these bacterial pathogens, we analyzed the T6SS gene content and architecture across the RSSC and their evolutionary relatives.
