This study identifies thiosulfinate tolerance gene clusters in onion-associated Burkholderia species and shows their role in allicin tolerance and growth in onion extracts.

This study identifies the genetic requirements for HiVir-mediated onion necrosis in Pantoea ananatis, showing that hvrB-hvrF are essential while hvrG-hvrJ are partially required, and highlights SNPs in deviant strains.

The paper identifies the AlgU sigma factor regulon in planta and shows its overlap with PTI-regulated genes in Pseudomonas syringae pv. tomato DC3000.

The paper investigates how genome context influences the evolutionary flexibility of nearly identical type III effectors in two phytopathogenic Pseudomonads through ICE elements.

This study investigates Xcm transmission from seeds to seedlings, finding that WT Xcm colonizes more effectively in susceptible plants and spreads systemically through vascular tissue.

The paper assesses the distribution of HiVir and alt virulence gene clusters in Pantoea spp. using PCR and RSN assays, finding significant associations with pathogenicity in onion rot.

This study identifies RpoS as a key factor enabling enteric pathogens to colonize plants during disease, highlighting its role in nutrient metabolism and stress response.

This study identifies a plasmid-borne gene cluster in Pantoea ananatis that enables tolerance to allicin and other thiosulfinates produced by Allium plants, revealing a chemical arms race between the pathogen and host.
