Caedibacter taeniospiralis is an obligate endosymbiont living in the cytoplasm of Paramecium tetraureliaC. 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.
متن کاملMore than the “Killer Trait”: Infection with the Bacterial Endosymbiont Caedibacter taeniospiralis Causes Transcriptomic Modulation in Paramecium Host
Endosymbiosis is a widespread phenomenon and hosts of bacterial endosymbionts can be found all-over the eukaryotic tree of life. Likely, this evolutionary success is connected to the altered phenotype arising from a symbiotic association. The potential variety of symbiont's contributions to new characteristics or abilities of host organisms are largely unstudied. Addressing this aspect, we focu...

Obligate bacterial endosymbionts of paramecia able to form refractile inclusion bodies (R bodies), thereby conferring a killer trait upon their ciliate hosts, have traditionally been grouped into the genus CAEDIBACTER: Of the six species described to date, only the Paramecium caudatum symbiont Caedibacter caryophilus has been phylogenetically characterized by its 16S rRNA gene sequence, and it ...

Holospora undulata is a micronucleus-specific symbiont of the ciliate Paramecium caudatum. We report here the draft genome sequence of H. undulata strain HU1. This genome information will contribute to the study of symbiosis between H. undulata and the host P. caudatum.
متن کاملThe killer trait of Paramecium and its causative agents1
Some paramecia express the so-called killer trait: killer paramecia release toxic particles into the environment and these particles kill sensitive Paramecium cells after ingestion. These particles are bacteria belonging to the genus Caedibacter, endosymbionts of killer Paramecium strains. A peculiarity of Caedibacter is the presence of an unusual structure termed R-body (refractile body) due t...
