The paper identifies an sRNA regulatory cascade in Dickeya solani that controls both antifungal and antibacterial activities by activating SlyA translation.

The paper develops TNSEEK, a pipeline for analyzing Tn-seq data across multiple bacterial strains, identifying conserved and strain-specific essential genes in Pectobacteriaceae.

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.

This study shows that the Dickeya-derived tailocin P2D1 targets phylogenetically distant Pseudomonas species, challenging the idea that tailocins only act against close relatives.

This study identifies genetic elements critical for pOXA-48 plasmid stability, replication, and conjugative transfer using transposon sequencing.

This study investigates the role of BlaPEC-1 beta-lactamase in the Soft Rot Pectobacteriaceae species complex, showing it functions as a public good that supports coexistence and protects sensitive strains during infection.

This study uses Tn-seq to identify metal resistance genes in Pseudomonas putida, revealing both known and novel genes involved in cadmium, copper, and cobalt resistance.
