Search for the remnant of plastid in the cell of Rhabdomonas sp.
Soukal, Petr ; Hampl, Vladimír (advisor) ; Oborník, Miroslav (referee)
Phylum Euglenozoa contsists of four groups - Euglenoidea, Kinetoplastea, Symbiontida and Diplonemea. Phototrophic euglenids, which constitute a clade, possess green plastid acquired via secondary endosymbiosis from green alga related to recent genus Pyramimonas. According to generally accepted plastid-late hypothesis, the endo- symbiosis took place after split between phototrophic euglenids and all other euglenozo- ans. Endosymbiotic event is always associated with gene transfer from endosymbiont to nuclei of host. Even if the endosymbiont is completely lost we should be able to observe enrichment of the host genome with the genes derived from endosymbiont. Some recent phylogenetic analyses uncovered genes related to green algae in trypanosomas (Kineto- plastea: Trypanosomatida). Based on this observation, authors postulated a hypothesis that the plastid was present already in common ancestor of kinetoplastids and euglenids and was lost in kinetoplastids and some euglenids including osmotrophic Rhabdomonas costata. During analysis of transcriptome of R. costata we found 63 genes, which could originated from green (24 genes) or other (49 genes) algae. In phylogenetic trees only one was robustly related to green and four were robustly related to other algae. Since the number of genes related to...
Transcriptomic and functional analysis of salivary proteins from the tick \kur{Ixodes ricinus}
CHMELAŘ, Jindřich
This thesis was focused on the identification and characterization of the salivary proteins from Ixodes ricinus, the European vector of Lyme disease and tick-borne encephalitis causative agents. In the first part of this work, the the transcriptomic approach was used in order to identify and describe I. ricinus salivary proteins. The second part is dealing with functional and structural characterization of the salivary protein named IRS-2 (I. ricinus serpin-2).
