Improved genome assemblies of plant-associated Streptomyces spp. as a resource for understanding plant pathogenicity in the genus

The paper improves genome assemblies for 12 pathogenic and 6 non-pathogenic Streptomyces type strains, revealing genomic features associated with plant pathogenicity.

Abiotic cues modulate exopolysaccharides to influence type VI secretion system-mediated antagonism

This study shows abiotic factors modulate exopolysaccharides in Agrobacterium fabrum, affecting T6SS-mediated antagonism by altering physical distance and attack efficacy.

Aeschynomene americana induces terminal bacteroid differentiation in Bradyrhizobium sp. USDA3516, a novel model for Dalbergioid-rhizobia symbiosis

This study identifies Bradyrhizobium sp. USDA3516 as a symbiont of Aeschynomene americana and shows that branched bacteroid morphology is not essential for effective symbiosis.

PathogenSurveillance: an automated pipeline for population genomic analyses and pathogen identification

PathogenSurveillance automates population genomic analyses of WGS data to enable rapid pathogen identification and biosurveillance.

Everything, everywhere, all at once - Surveillance and molecular epidemiology reveal Melissococcus plutonius is endemic among Michigan, US beekeeping operations of all sizes and present in some honey bee colonies year-round

This study uses surveillance and molecular epidemiology to show Melissococcus plutonius is widespread in Michigan beekeeping operations and present year-round, with seasonal infection peaks and genetic diversity within hives.

Modular evolution of secretion systems and virulence plasmids in a bacterial species complex

The paper analyzes genome diversity in Agrobacterium tumefaciens to study the evolution of secretion systems and virulence plasmids, revealing gene losses, horizontal transfers, and modularity in molecular evolution.
