Phylogenetic analyses of partial sequences of gyrB and recA are consistent with previous analyses limited to 16S rRNA gene sequences and yield improved confidence of the evolutionary relationships of these symbionts.Abstract:
Ecological studies on three bacterial lineages symbiotic in aphids have shown that they impose a variety of effects on their hosts, including resistance to parasitoids and tolerance to heat stress. Phylogenetic analyses of partial sequences of gyrB and recA are consistent with previous analyses limited to 16S rRNA gene sequences and yield improved confidence of the evolutionary relationships of these symbionts. All three symbionts are in the Enterobacteriaceae. One of the symbionts, here given the provisional designation “Candidatus Serratia symbiotica,” is a Serratia species that has acquired a symbiotic lifestyle. The other two symbionts, here designated “Candidatus Hamiltonella defensa” and “Candidatus Regiella insecticola,” are sister groups to one another and together show a relationship to species of Photorhabdus.read more

TL;DR: The genome of the pea aphid shows remarkable levels of gene duplication and equally remarkable gene absences that shed light on aspects of aphid biology, most especially its symbiosis with Buchnera.

Facultative Symbionts in Aphids and the Horizontal Transfer of Ecologically Important Traits
TL;DR: Experiments on pea aphids have demonstrated that facultative symbionts protect against entomopathogenic fungi and parasitoid wasps, ameliorate the detrimental effects of heat, and influence host plant suitability.

Aphid Protected from Pathogen by Endosymbiont
TL;DR: It is shown that one of the three most common facultative symbionts of pea aphid (Acyrthosiphon pisum), the bacterium Regiella insecticola, has a major effect on host resistance to a fungal pathogen.

Bacterial communities of diverse Drosophila species: ecological context of a host-microbe model system.
TL;DR: It is found that Drosophilid flies have taxonomically restricted bacterial communities, with 85% of the natural bacterial microbiome composed of only four bacterial families, suggesting that the host exercises some level of control over the bacteria that inhabit its digestive tract.
