Abstract

ABSTRACTCaedibacter taeniospiralis is an obligate endosymbiont living in the cytoplasm of Paramecium tetraurelia. C. taeniospiralis causes the so-called killer trait, eliminating intraspecific competitors of its host when released into the medium by the concerted action of the unusual protein structure R-body (refractile body) in addition to an as-yet-unknown toxin.

Highlights

Caedibacter taeniospiralis is an obligate endosymbiont living in the cytoplasm of Paramecium tetraurelia
Gene annotation of the draft sequence was carried out using Prodigal (11), tRNAscan-SE (12), and RNAmmer (13) software tools
The genome sequence of C. taeniospiralis strain 51K will improve our understanding of this organism and its symbiotic interaction with P. tetraurelia, including and in addition to the killer trait
