Comparative Genomics and Pathogenicity Analysis of Two Bacterial Symbionts of Entomopathogenic Nematodes: The Role of the GroEL Protein in Virulence

Bacteria of the genera Xenorhabdus and Photorhabdus are symbionts of entomopathogenic nematodes.Despite their close phylogenetic relationship, they show differences in their pathogenicity and virulence mechanisms in target insects.These differences were explored by the analysis of the pangenome, as it provides a framework for characterizing and def
