Risk assessment of interspecific hybridization between endemic Campanula bohemica and widespread C. rotundifolia s.l.
Hanušová, Kateřina ; Suda, Jan (advisor) ; Krahulec, František (referee)
The thesis deals with phenotypic, ploidy and genetic variation of two Campanula species occurring in the Krkonoše Mts., namely the endemic C. bohemica and widespread C. rotundifolia subsp. rotundifolia. For comparative purposes subspecies sudetica of the latter species was also included. The main aim was to get insight into population structure and assess the threat of interspecific hybridization to the survival of the endemic bluebell. Flow cytometry, distance-based morphometrics and molecular analysis were used to address these questions. Three distinct groups of fluorescence intensities were revealed by flow cytometry, corresponding to DNA diploids, tetraploids and pentaploids. While diploids morphologically matched the nominate subspecies of C. rotundifolia, tetraploids corresponded either to C. rotundifolia subsp. sudetica or C. bohemica. Most populations from the Krkonoše Mts. were uniform although a sympatric growth of diploids and tetraploids was encountered in 12 populations. Only two pentaploids individuals, most likely of hybrid origin, were found, which indicated that interspecific hybridization is much less common than previously assumed. The two tetraploid taxa were distinguished by molecular markers. A combination of flow cytometry and molecular analyses thus allowed reliable...

Biotransformation of monepantel in plant (Campanula rotundifolia, Plantago lanceolata)
Crhová, Anna ; Raisová Stuchlíková, Lucie (advisor) ; Vokřál, Ivan (referee)
Charles University in Prague Faculty of Pharmacy in Hradec Králové Department of Biochemical Sciences Candidate: Bc. Anna Crhová Supervisor: RNDr. Lucie Stuchlíková Raisová, Ph.D. Title of diploma thesis: Biotransformation of monepantel in plants (Campanula rotundifolia, Plantago lanceolata) Anthelmintics are veterinary drugs used to eliminate disease caused by parasitic worms. Monepantel (MOP) is a representative of amino-acetonitrile derivatives. This relatively new group of drugs is effective on helminthic strains, which are resistant to classic therapy (benzimidazoles, makrocyklic lactones, imidazothiazoles). Due to high consuption of these drugs, it is important to find out their fate in the exposed organisms. Anthelmintics are in contact with the environment and they can affect terrestrial and aquatic organisms. Their various forms can be accumulate in plants. These plants can be eaten by the animal, which may lead to development of resistance in helminths. In addition, the physiology of plants and animals may be disrupt and, consequently, biodiversity loss may occur. The aim of this study was to determine the biotransformation processes occurring in ribwort plantain (Plantago lanceolata) and harebell (Campanula rotundifolia) after low concentrations of MOP. Suspensions of both plants cells...
