Multiple origins of endosymbiosis within the Enterobacteriaceae (gama-Proteobacteria): convergence of complex phylogenetic approaches

Popis výsledku v původním jazyce

In this study, we address the monophyly versus polyphyly of enterobacterial symbionts by exploring a multigene matrix within a complex phylogenetic framework. We assembled the richest taxon sampling of Enterobacteriaceae to date (50 taxa, 69 orthologousgenes with no missing data) and analyzed both nucleic and amino acid data sets using several probabilistic methods. The results of this study confirm the efficiency of several artifact-reducing methods and strongly point towards the polyphyly of P-symbionts within Enterobacteriaceae. Interestingly, the model species of symbiotic bacteria research, Buchnera and Wigglesworthia, originated from closely related, but different, ancestors. The possible origins of intracellular symbiotic bacteria from gut-associated or pathogenic bacteria are suggested, as well as the role of facultative secondary symbionts as a source of bacteria that can gradually become obligate maternally transferred symbionts.
