| Outline of Final Research Achievements |
Termites harbor protists and prokaryotes in their guts. Furthermore the protists generally establish a symbiotic relationship with multiple species of prokaryotes, which reside in their cytoplasm, attach onto the cell surface or nucleoplasm. However the functions of the symbionts and the symbiotic mechanisms mostly remain unclear due to difficulties to culture the symbionts and the hosts. In this study, we have performed a genome analysis of intranuclear Verrucomicrobial symbionts of Trichonympha agilis. The genome analysis suggests that the intranuclear symbionts are not able to synthesize many metabolites and depend on the host for the metabolites. In addition, the genomes have partial genes for type III secretion system, suggesting that the type III secretion system is possibly utilized for the host-symbiont interaction. The genome analysis of intranuclear symbionts revealed part of the symbiotic relationship with the host.
