	Legionella Becoming a Mutualist: Adaptive Processes Shaping the Genome of Symbiont in the Louse Polyplax serrata ŘÍHOVÁ, Jana Genomic modifications coupled with the first known transition of a Legionella bacterium to symbiosis with insects (louse Polyplax serrata). Apart from characteristics typical for other obligatory symbionts in insect (genome reduction), the main innovation of the genome consists in horizontal acquisition of complete biotin operon. Comparative genomic analysis with free living legionellae and other symbiotic bacteria demonstrates convergent evolution of several phylogenetically unrelated louse symbionts. Detailed record
	The symbiotic bacteria of lice of genus \kur{Polyplax}: general phylogenetic and genomic characterisation ŘÍHOVÁ, Jana Blood-sucking lice of the genus Polyplax harbour two bacterial endosymbionts, one from family Legionellales and the other from family Neisseriales. Fylogenetic and genomic analyses reveal typical features of endosymbiotic bacteria and coevolution history with the host. In the genome of the endosymbiont from family Legionellales I found operon, which encodes biosynthesis of biotin, essential vitamin, especially for blood-sucking insects living on low-nutrient diet. This operon was probably horizontally transfer from Wolbachia, nutrient endosymbiont of bedbug Cimex lectularius. Detailed record
	Assembly and annotation of a mitochondrial genome of kinetoplastid protist \kur{Perkinsela}. DAVID, Vojtěch This thesis is based on a collaborative project between Laboratory of Molecular Biology of Protists led by Prof. Julius Lukeš and the laboratory of John Archibald (Department of Biochemistry & Molecular Biology, Dalhousie University, Canada). My contribution to the project, as the name of the thesis suggests is to process DNA and RNA sequencing data from Neoparamoeba pemaquidensis isolate that correspond to the mitochondrion of Perkinsela, also called Ichthyobodo-related organism (IRO). The main aim is to characterize mitochondrial gene content and to attempt to understand the mechanism of U-insertion/deletion RNA editing in Perkinsela and its evolution. Detailed record
