Using unbiased high-throughput sequencing for metagenomic screening of viruses in diseased tomato plants, we identified a viral complex that includes viruses previously reported in tomato crops on La Réunion Island as well as a novel polerovirus, tentatively named "tomato necrotic yellowing virus" (ToNYV, proposed species, " Polerovirus ToNYV "). Molecular characterization and phylogenetic analysis revealed that ToNYV is close...

This is the first description of the complete genome sequence of a new monopartite begomovirus isolated from tomato leaves with symptoms of tomato (yellow) leaf curl disease collected on Reunion Island, for which we propose the name "tomato yellow leaf curl Reunion virus" (TYLCREV). Phylogenetic analysis showed that TYLCREV belongs to the Old World monopartite begomoviruses and is most closely related to tomato yellow leaf cur...

Plasmids provide an efficient vehicle for gene sharing among bacterial populations, playing a key role in bacterial evolution. Network approaches are particularly suitable to represent multipartite relationships and are useful tools to characterize plasmid‐mediated gene sharing events. The bacterial family Lysobacteraceae includes plant commensal, plant pathogenic and opportunistic human pathogens for which plasmid‐mediated ad...

Horizontal gene transfer is of major evolutionary importance as it allows for the redistribution of phenotypically important genes among lineages. Such genes with essential functions include those involved in resistance to antimicrobial compounds and virulence factors in pathogenic bacteria. Understanding gene turnover at microevolutionary scales is critical to assess the pace of this evolutionary process. Here, we characteriz...
