The effect of mycorrhiza on production of plant secondary metabolites
Pikorová, Markéta ; Albrechtová, Jana (advisor) ; Rydlová, Jana (referee)
Mycorhizal symbiosis, mutualistic relationship between symbiotic fungus and plant roots, is ranked among important interspecies interactions. It is indicated that about 90% terrestrial vascular plants live in this symbiosis. Arbuscular mycorrhiza (AM) is the most often occurring type of mycorrhiza and simultaneously the most often occurring type of symbiosis of higher plants. Approximately 80% of all of plant species form this symbiosis. By symbiotic coexistence with fungus plant often gains benefits as for example higher tolerance against stress factors, resistance against pathogens or improvement of nutrient uptake. In recent years in series of works is detected that mycorrhiza positively influences production of plant secondary metabolites. This influence can display quantitativelyby increase of metabolite in plant and also qualitatively by change spectrum of substances produced. These substances can have importance in different spheres for human. Medicinal research regularly extends spectum of substances with bioactive effect which have origin just in the plant secondary metabolism. Target of this thesis is, by the form of literary retrieval, to create an overview of recent state of research regarding of influence of mycorhizal symbiosis on content of secondary metabolites in plants, especially...

Analysis of Crisis Communication in the Babies Switched at Birth in the Hospital of Třebíč Case
Böhm, Jiří ; Lešetický, Ondřej (advisor) ; Rydlová, Jana (referee)
The theoretical part of this thesis focuses mainly on crisis communication and its goal is to pinpoint its instruments, principles and regularities. The theoretical part also defines the concept of crisis and offers an adequate guide on what action should management take in individual periods of crisis. Apart from crisis communication and crisis management, it also explains the regularities of media analysis, which is used as an information portfolio for the second, practical part. The result is an evaluation of crisis communication during the events of "babies switched at birth in the hospital of Třebíč" from the hospital's perspective, mostly based on aforementioned media analysis. Adequate recommendations are proposed, based on the results.
