Genomics and evolution of heritable bacterial symbionts.
Insect heritable symbionts have proven to be ubiquitous, based on molecular screening of various insect lineages. Recently, molecular and experimental approaches have yielded an immensely richerExpand

A Metagenomic Survey of Microbes in Honey Bee Colony Collapse Disorder
In colony collapse disorder (CCD), honey bee colonies inexplicably lose their workers. CCD has resulted in a loss of 50 to 90% of colonies in beekeeping operations across the United States. TheExpand

The gut microbiota of insects - diversity in structure and function.
Insect guts present distinctive environments for microbial colonization, and bacteria in the gut potentially provide many beneficial services to their hosts. Insects display a wide range in degree ofExpand

Extreme genome reduction in symbiotic bacteria
Since 2006, numerous cases of bacterial symbionts with extraordinarily small genomes have been reported. These organisms represent independent lineages from diverse bacterial groups. They haveExpand

Facultative bacterial symbionts in aphids confer resistance to parasitic wasps
Symbiotic relationships between animals and microorganisms are common in nature, yet the factors controlling the abundance and distributions of symbionts are mostly unknown. Aphids have an obligateExpand

Facultative symbionts in aphids and the horizontal transfer of ecologically important traits.
Aphids engage in symbiotic associations with a diverse assemblage of heritable bacteria. In addition to their obligate nutrient-provisioning symbiont, Buchnera aphidicola, aphids may also carry oneExpand

A simple and distinctive microbiota associated with honey bees and bumble bees
Specialized relationships with bacteria often allow animals to exploit a new diet by providing a novel set of metabolic capabilities. Bees are a monophyletic group of Hymenoptera that transitioned toExpand

Symbiosis and Insect Diversification: an Ancient Symbiont of Sap-Feeding Insects from the Bacterial Phylum Bacteroidetes
ABSTRACT Several insect groups have obligate, vertically transmitted bacterial symbionts that provision hosts with nutrients that are limiting in the diet. Some of these bacteria have been shown toExpand
