Flow constraints at infection site shape multiplication-dissemination trade-offs and opposite regulatory programs of Xanthomonas and Ralstonia xylem pathogens

This study shows how xylem sap flow constraints shape opposite regulatory strategies in two plant pathogens, Xcc and Rs, to mitigate trade-offs between virulence traits.

Rhizobial motility preference in root colonization of Medicago truncatula

This study investigates how rhizobia move within root infection threads using modeling, imaging, and mutant analysis, finding that flagella-independent surface translocation and rhizobactin 1021 secretion are key for colonization.

Insights into the metabolic specificities of pathogenic strains from the Ralstonia solanacearum species complex

The paper compares metabolic pathways across 11 Ralstonia solanacearum strains to identify differences contributing to strain diversification and pathogenicity.

The population dynamics of a bacterial pathogen after host re-infection affects the founding population size

This study investigates how host re-infection affects pathogen founding population size, showing that increased temperature reduces founding population size by limiting subsequent re-infection contributions.
