Reduced Genome of the Gut Symbiotic Bacterium "Candidatus Benitsuchiphilus tojoi" Provides Insight Into Its Possible Roles in Ecology and Adaptation of the Host Insect.

ABSTRACT: Diverse animals, including insects, harbor microbial symbionts within their gut, body cavity, or cells. The subsocial parastrachiid stinkbug Parastrachia japonensis is well-known for its peculiar ecological and behavioral traits, including its prolonged non-feeding diapause period and maternal care of eggs/nymphs in an underground nest. P. japonensis harbors a specific bacterial symbiont within the gut cavity extracellularly, which is vertically inherited through maternal excretion of symbiont-containing white mucus. Thus far, biological roles of the symbiont in the host lifecycle has been little understood. Here we sequenced the genome of the uncultivable gut symbiont "Candidatus Benitsuchiphilus tojoi." The symbiont has an 804 kb circular chromosome encoding 606 prot
