The paper identifies AvrC as a rhamnosyltransferase with broad substrate specificity, showing it can modify plant proteins like RIN4, COPE1, and COPZ1.

The paper investigates the transmission routes of Pseudomonas syringae strains causing zucchini diseases, finding that VCZ strains are predominantly transmitted via floral pathways while BLS strains use pericarp transmission.

This study shows that Burkholderia gladioli pv. alliicola detoxifies thiosulfinates during onion bulb infection but not foliar infection, using a reporter strain to track exposure.

This study analyzes the genomic diversity and evolutionary dynamics of Pectobacterium jejuense across hosts and geographic regions, revealing homologous recombination and genome plasticity as key drivers of adaptation and pathogenic evolution.

This study uses phylogenomic and comparative genomic analyses of 104 Erwinia genomes to resolve evolutionary relationships, identify taxonomic inconsistencies, and uncover lineage-specific genomic features associated with virulence and ecological adaptation.

The paper characterizes type III effector diversity and conservation across Xanthomonas pathogens causing bacterial spot of pepper and tomato, revealing core effectors and population-specific variation.

This study shows that ToBRFV and PepMV differentially affect bacterial disease severity in tomatoes, either increasing or decreasing symptom expression depending on the pathogen.

The paper shows hydathodes are both entry points for pathogens and critical for limiting their spread in plant leaves.

The paper identifies Xanthomonas euvesicatoria effectors recognized by Solanum americanum immune receptors, showing their role in effector-triggered immunity and bacterial infection.

This study provides field evidence that Thrips hawaiiensis can acquire Ralstonia solanacearum from infected banana flowers, supporting its role as a potential vector for Bugtok disease in cooking bananas.

This study identifies a conserved Rhs module in Stenotrophomonas species linked to T6SS effector innovation and immunity, enabling ecological adaptation in saline niches.

The paper shows that single-nucleotide mutations in the sRNA ArcZ of Dickeya solani generate social cheater variants during potato infection, which exploit a shared metabolic benefit without contributing to it.

The paper shows a temperate bacteriophage in Pseudomonas syringae enhances virulence by altering T3SS operon expression, independent of its effector gene.

This study identifies T2S-secreted effectors in Xanthomonas species and shows their roles in plant cell wall remodeling and nutrient utilization across different pathovars.

The paper quantifies the efficiency of different transmission routes for Xanthomonas citri pv. fuscans and other seed-borne bacteria to bean seeds, finding the vascular route most efficient and identifying plant immunity as a bottleneck.

This study evaluates βhpmeh transgenic potato plants for resistance to bacterial wilt caused by Ralstonia solanacearum, finding reduced susceptibility correlated with βhpmeh gene expression.

This study observes specific patho-phenotypes in tomato leaves infiltrated with Ralstonia pseudosolanacearum, including petiole bending, epinasty, and senescence, which are hrp-dependent and not seen with other bacteria.

This study investigates Xanthomonas translucens' disease mechanisms in cereals, showing that xanthan suppresses host immunity while the Type III Secretion System is not sufficient for disease development.

The paper uses whole genome sequencing of soft rot Pectobacteriaceae isolates from Danish potato farms to trace disease spread and identify potential phage-based biocontrol strategies.
