Abstract
Termites harbor an abundance and diversity of symbiotic microbes in their gut that comprise all the three domains of life: Eucarya, Bacteria, and Archaea. One of the most prominent features of this microbiota is the cellular association of the gut flagellates with eubacteria and/or methanogenic archaea. The eubacterial and methanogenic symbionts are observed both inside and on the surface of the host flagellate cells. Although molecular approaches have gradually revealed the phylogenetic and spatial structures of these as-yet-uncultivable symbiotic complexes, their functions remain largely unknown. Recently, a method to acquire the complete genome sequence of uncultured bacterial species from a small number of cells has been developed; two complete genome sequences of endosymbiotic eubacteria of termite gut flagellates have been decoded. This novel genomic approach is expected to provide a great progress in the studies of this multilayered symbiotic system in termite gut.
