Insects have established mutualistic symbiotic interactions with microorganisms that are
beneficial to both host and symbiont. Many insects have exploited these symbioses to …

Many eukaryotes have obligate associations with microorganisms that are transmitted
directly between generations. A model for heritable symbiosis is the association of aphids, a …

All vertically transmitted bacterial symbionts undergo a process of genome reduction over
time, resulting in tiny, gene-dense genomes. Comparison of genomes of ancient bacterial …

Cockroaches are a group of insects that evolved early in geological time. Because of their
antiquity, they for the most part display generalized behavior and physiology and …

Comparative genomics from mitochondria, plastids, and mutualistic endosymbiotic bacteria
has shown that the stable establishment of a bacterium in a host cell results in genome …

Ancient endosymbionts have been associated with extreme genome structural stability with
little differentiation in gene inventory between sister species. Tsetse flies (Diptera …

Metagenome analysis of the gut symbionts of three different insects was conducted as a
means of comparing taxonomic and metabolic diversity of gut microbiomes to diet and life …

Beneficial microbial associations with insects are common and are classified as either one
or a few intracellular species that are vertically transmitted and reside intracellularly within …

Many insect species have established long-term symbiotic relationships with intracellular
bacteria. Symbiosis with bacteria has provided insects with novel ecological capabilities …

Nutritional symbionts of insects include some of the most bizarre genomes studied to date,
with extremely reduced size, biased base composition, and limited metabolic abilities. A …
