Abstract
Comparative analysis of the genes coding for 16S rRNA of the type stra ins of Xenorhabdus and Photorhabdus species indicates the close phylog enetic relationship of these two genera. However, distance matrix anal yses do not unambiguously separate the symbionts of entomopathogenic n ematodes according to their assignment into different genera. When var ious 16S rRNA gene sequences from a selection of members of the gamma subclass of Proteobacteria and outgroup taxa were used, the intragener ic relationships of Xenorhabdus species and the positions of Photorhab dus luminescens and related species changed significantly.
