TL;DR: The genome sequencing of Buchnera aphidicola BCc from the aphid Cinara cedri revealed that this bacterium had lost its symbiotic role, as it was not able to synthesize tryptophan and riboflavin, and an evolutionary scenario of the transition from facultative to obligate endosymbiont is proposed.

TL;DR: A highly dynamic dual symbiotic system in this aphid lineage is revealed and it is proposed that symbiont succession was driven by factors intrinsic to the phenomenon of endosymbiosis, such as rapid genome deterioration or competitive interactions between bacteria with similar metabolic capabilities.

TL;DR: The genome of S. symbiotica strain SCt-VLC from the aphid C. tujafilina shows a variety of metabolic, genetic, and architectural features, which point toward this endosymbiont being one step closer to an obligate intracellular one.

TL;DR: The genome of both Buchnera and S. symbiotica is sequenced to provide further evidence for the previously proposed establishment of a secondary co-obligate endosymbiont in the common ancestor of the Lachninae aphids, and it is proposed that the putative convergent split of the tryptophan biosynthetic role between Buchnero-Cedri and Cinara-Cupressobium could be behind the establishment of S

TL;DR: The recent availability of data on several endosymbiotic bacteria is enabling us to form a comprehensive picture of the genome‐reduction process and the phenotypic consequences for the dwindling symbiont.
