Summary
The aim of the present PhD project is to investigate bacterial endosymbionts
and ectosymbionts of ciliates, belonging to Phylum Verrucomicrobia,
from a genomic and phylogenetic point of view.
The first goal of this study is to improve the knowledge about
the diversity and distribution of verrucomicrobial endosymbionts in
ciliates. Therefore it was decided to focus on genus Euplotes due to its
propensity to harbor symbiotic bacteria and due to preliminary data
report on the presence of symbiotic Verrucomicrobia in some Euplotes
strains from our laboratory culture collection.
The second goal of this study is the characterization from a genomic
point of view of an already known ectosymbionts of the ciliate
Euplotidium itoi, the so called Epixenosome.
Along these two main goals, a very important milestone is the
production of an updated review on the knowledge about the phylum
Verrucomicrobia, a task not attended by anyone so far, but truly needed
due to increase of studies regarding Verrucomicrobia
