Complete genome of the mutualistic symbiont "Candidatus Nardonella sp." Pin-AIST from the black hard weevil Pachyrhynchus infernalis

The complete genome, 226,287 bps in size, of "Candidatus Nardonella sp." Pin-AIST, an obligatory bacterial endosymbiont of the black hard weevil Pachyrhynchus infernalis, was sequenced. The extremely reduced endosymbiont genome is specialized for tyrosine synthesis, which contributes to the hardness of the beetle's exoskeleton.
