“…This might reflect that the ancestors of these endosymbionts shared the same ecological niche at some point in evolutionary history. Amoebae are believed to have contributed to the development of key features for survival in eukaryotic host cells by Cardinium and Rickettsia progenitors (Bordenstein and Reznikoff, 2005;Molmeret et al, 2005;Weinert et al, 2009;Penz et al, 2012). For instance, many genes of R. bellii are more related to amoebal symbionts than to other Rickettsia, an observation compatible with an ancestor of R. bellii infecting amebas and exchanging genes with other amoebal symbionts (Ogata et al, 2006).…”

Various bacteria live exclusively within arthropod cells and collectively act as an important driver of arthropod evolutionary ecology. Whereas rampant intra-generic DNA transfers were recently shown to have a pivotal role in the evolution of the most common of these endosymbionts, Wolbachia, the present study show that inter-generic DNA transfers also commonly take place, constituting a potent source of rapid genomic change. Bioinformatic, molecular and phylogenetic data provide evidence that a selfish genetic element, the insertion sequence ISRpe1, is widespread in the Wolbachia, Cardinium and Rickettsia endosymbionts and experiences recent (and likely ongoing) transfers over long evolutionary distances. Although many ISRpe1 copies were clearly expanding and leading to rapid endosymbiont diversification, degraded copies are also frequently found, constituting an unusual genomic fossil record suggestive of ancient ISRpe1 expansions. Overall, the present data highlight how ecological connections within the arthropod intracellular environment facilitate lateral DNA transfers between distantly related bacterial lineages.

“…Hereafter, we discuss these possibilities under the light of phylogenetic, evolutionary and other lines of evidence available to date. Given that the scenario (i) applies, symbiont swapping within and between the host lineages would result in occurrences of genetically identical or close symbiont genotypes within and between the host insect species, which would generate a compact symbiont phylogeny with short terminal branches, as commonly observed with Wolbachia, Rickettsia, Serratia, Hamiltonella, Regiella and other facultative insect symbionts (Russell et al, 2003;Baldo et al, 2006;Weinert et al, 2009). Oddly, however, such phylogenetic patterns are not observed with the Sodalis-allied Sitophilus symbionts: the symbiont genotypes are remarkably divergent within and between the host weevil species, with long terminal branches giving a combor star-like appearance of the phylogeny (Figures 4 and 5).…”

The processes and mechanisms underlying the diversification of host-microbe endosymbiotic associations are of evolutionary interest. Here we investigated the bacteriocyte-associated primary symbionts of weevils wherein the ancient symbiont Nardonella has experienced two independent replacement events: once by Curculioniphilus symbiont in the lineage of Curculio and allied weevils of the tribe Curculionini, and once by Sodalis-allied symbiont in the lineage of grain weevils of the genus Sitophilus. The Curculioniphilus symbiont was detected from 27 of 36 Curculionini species examined, the symbiont phylogeny was congruent with the host weevil phylogeny, and the symbiont gene sequences exhibited AT-biased nucleotide compositions and accelerated molecular evolution. These results suggest that the Curculioniphilus symbiont was acquired by an ancestor of the tribe Curculionini, replaced the original symbiont Nardonella, and has co-speciated with the host weevils over evolutionary time, but has been occasionally lost in several host lineages. By contrast, the Sodalis-allied symbiont of Sitophilus weevils exhibited no host-symbiont co-speciation, no AT-biased nucleotide compositions and only moderately accelerated molecular evolution. These results suggest that the Sodalis-allied symbiont was certainly acquired by an ancestor of the Sitophilus weevils and replaced the original Nardonella symbiont, but the symbiotic association must have experienced occasional re-associations such as new acquisitions, horizontal transfers, replacements and/or losses. We detected Sodalis-allied facultative symbionts in populations of the Curculionini weevils, which might represent potential evolutionary sources of the Sodalis-allied primary symbionts. Comparison of these newcomer bacteriocyte-associated symbiont lineages highlights potential evolutionary trajectories and consequences of novel symbionts after independent replacements of the same ancient symbiont.
