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.
Journal ArticleDOI
Wolbachia as a bacteriocyte-associated nutritional mutualist
TL;DR: Results indicate that bacteriocyte-associated nutritional mutualism can evolve from facultative and prevalent microbial associates like Wolbachia, highlighting a previously unknown aspect of the parasitism-mutualism evolutionary continuum.
Journal ArticleDOI
Host Plant Specialization Governed by Facultative Symbiont
TL;DR: In North America and Europe, the pea aphid encompasses ecologically and genetically distinct host races, offering a model system for studies on sympatric speciation.
Journal ArticleDOI
Evolutionary Relationships of Three New Species of Enterobacteriaceae Living as Symbionts of Aphids and Other Insects
TL;DR: 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.
Journal ArticleDOI
Horizontal Gene Transfer from Diverse Bacteria to an Insect Genome Enables a Tripartite Nested Mealybug Symbiosis

TL;DR: Genome and transcriptome sequencing reveals that the extreme genomic degeneracy of Tremblaya PCIT likely resulted from acquiring Moranella as an endosymbiont, and indicates that the functioning of this three-way symbiosis is dependent on genes from at least six lineages of organisms.
