Molecular phylogeny of Heterorhabditis and Steinernema and their symbiotic bacteria.What is true and what is wrong: impact on the evolutionary historyof these organisms?

Description

Abstract: By associating sequences available in databases and those obtained from theentomopathogenic nematodes preserved in our own collection at INRA Montpellier, we obtainednew insights into the phylogeny of Heterorhabditis and Steinernema and highlighted, by treetopologyreconciliation analyses, that Heterorhabditis-Photorhabdus and Steinernema-Xenorhabdus have evolved using different events including cospeciations; sortings and hostswitches.
