The paper develops and validates a metagenomics workflow to identify bacterial spot pathogens and virulence factors in Ohio tomato and pepper production using shotgun sequencing.

This study shows that loss of the inaZ gene, which enables ice nucleation activity, restricts bacterial dispersal and leads to genetic and ecological isolation.

The paper examines the distribution and expansion of a specific IS5 subclass in Pseudomonas syringae genomes, finding recent independent expansions and variable insertion site conservation.

This study identifies EPS-I as a key factor enabling Ralstonia solanacearum biofilms to exhibit viscoelastic fluid behavior, enhancing pathogen dissemination in planta.

The paper identifies Pseudomonas coronafaciens pv. coronafaciens causing BHB in Idaho oat fields and reports resistant barley genotypes.

This study uses tissue-specific experimental evolution to identify adaptive traits in Clavibacter michiganensis, revealing trade-offs between vascular persistence and systemic virulence.

The paper investigates phage-bacterial interactions in plant agroecosystems, finding nested network structures and phylogeny-driven defense systems.

This study shows that gene loss and gain in Xanthomonas translucens drive host range shifts, with fitness costs for generalist behavior and enhanced virulence for specialist behavior.

This study shows that the Ralstonia solanacearum type III effector RipUK60 disrupts plant cytoskeleton organization to enhance bacterial virulence.

The paper develops a greenhouse spray inoculation protocol to screen barley germplasm for resistance against Xanthomonas translucens pv. translucens, confirming moderate resistance in cultivar Quest across diverse strains.

This study shows that rpfF is not essential for X. translucens pv. undulosa pathogenesis, suggesting quorum sensing interference is not a viable strategy for preventing bacterial leaf streak.

The paper compares the genomes of Minnesotan Xanthomonas translucens strains and finds overall genomic similarity but diversity in virulence factors.

The paper identifies a novel class of sRNAs in rice induced by bacterial infection, which may play a role in plant-microbe interactions.
