Bacterial endosymbionts in animals.
Molecular phylogenetic studies reveal that many endosymbioses between bacteria and invertebrate hosts result from ancient infections followed by strict vertical transmission within host lineages. Endosymbionts display a distinctive constellation of genetic properties including AT-biased base composition, accelerated sequence evolution, and, at least sometimes, small genome size; these features ...
متن کاملGenome degeneration affects both extracellular and intracellular bacterial endosymbionts
The obligate intracellular bacterial endosymbionts of insects are a paradigm for reductive genome evolution. A study published recently in BMC Biology demonstrates that similar evolutionary forces shaping genome structure may also apply to extracellular endosymbionts.
متن کاملMolecular evolution in bacterial endosymbionts of fungi.
The prediction that progressive coupling of host and symbiont metabolic and reproductive interests leads to reduced mixing of symbiont lineages has been verified extensively in maternally transmitted bacterial endosymbionts of insects. To test whether this prediction is also applicable to associations of bacteria with fungi, we explored patterns of molecular evolution in two lineages of mutuali...
متن کاملSecondary ( -Proteobacteria) Endosymbionts Infect the Primary ( -Proteobacteria) Endosymbionts of Mealybugs Multiple Times and Coevolve with Their Hosts
Mealybugs (Hemiptera, Coccoidea, Pseudococcidae) are plant sap-sucking insects that have within their body cavities specialized cells containing prokaryotic primary endosymbionts (P-endosymbionts). The Pendosymbionts have the unusual property of containing within their cytoplasm prokaryotic secondary endosymbionts (S-endosymbionts) [C. D. von Dohlen, S. Kohler, S. T. Alsop, and W. R. McManus, N...
متن کاملBacterial endosymbionts in field-collected samples of Trialeurodes sp. nr. abutiloneus (Hemiptera: Aleyrodidae).
Facultative bacterial endosymbionts are common, influential associates of arthropods, yet their movement among host species has not been well documented. Plant-mediated transmission of Rickettsia has been shown for the whitefly Bemisia tabaci. Bemisia tabaci in USA cotton fields harbors the secondary symbionts Rickettsia and Hamiltonella, and co-occurs with Trialeurodes sp. nr. abutiloneus whit...
