Effect of Enlargement of Consolidated Group on its Economy
Ševčíková, Hana ; Tumpach, Miloš (referee) ; Rajchlová, Jaroslava (advisor)
The master's thesis focuses on the expansion of the consolidated group and the impact on economic situation consolidated group due the expansion. Theoretical part of the thesis focuses on consolidated financial statements, company valuation and assessment of the economic situation. In the second part is determined company value and then the company is included to consolidation group by using method of consolidation. After that is assessed the economic impact of the extension group.

Cytokinines and their role in plant cell division, with accent on G2/M transition
Prášilová, Jana ; Ševčíková, Hana (advisor) ; Bíšová, Kateřina (referee)
The eukaryotic cell cycle is well understood mainly in yeasts and animals. Basic regulatory mechanisms, with cyclin-dependent kinases (CDKs) playing crucial roles, are similar in all eukaryotes including plants. CDKs operate mainly at the key cell cycle checkpoints, G1/S and G2/M. Phosphorylation and dephosphorylation of CDKs by kinases and phosphatases have both negative and positive effect. Negative regulator at the G2/M transition is WEE1 kinase which phosphorylates conserved amino acid residues T14 and Y15 of CDK. Phosphatase CDC25 removes this inhibitory phosphate in yeasts and animals and forces cells into mitosis. Plant cell cycle exhibits remarkable differences. Importantly, it is controlled by phytohormones, and some key points of regulation remain obscure - a functional plant homologue of yeast CDC25 phosphatase has not been found in plants yet though Y15 inhibitory phosphorylation by WEE1 kinase blocks mitosis entry in plants as well. Thus, the regulatory mechanism of G2/M transition in plant cells is still to be found. Phytohormones play a key role, not only in the plant cell cycle, but in whole plant development. Interplay between the two groups of phytohormones: auxins and cytokinins, is crucial. Especially cytokinins significantly influence the regulation of G2/M checkpoint. It is...

Regulation of morphogenic processes in potato - the role of sugar metabolism
Ševčíková, Hana ; Lipavská, Helena (advisor) ; Navrátil, Oldřich (referee) ; Langhansová, Lenka (referee)
Potato (Solanum tuberosum) tuberization is a complex, strictly regulated morphogenic process. Since potato is one of the most important crops in the world, understanding the regulation of this process is gaining in importance not only from a theoretical but also from a practical point of view. This work focuses on the role of sugars, which can serve not only as an energy and building material sources, but also as an important signal regulating many developmental processes including the tuberization. As a primary experimental material potato cv. Lada (WT) and its spontaneously tuberizing (ST) mutant was used. Since the previous results with ST plants suggested altered carbohydrate partitioning between plant organs and significant difference in total carbohydrate contents between ST plants and the WT (Fischer et al. 2008), in the first manuscript presented, the aim was to examine in detail the sugar metabolism of ST plants grown in vitro mixotrophically (MT) and photoautotrophically (PA). We observed changes in soluble carbohydrate allocation and starch deposition, favouring basal stem part in ST. Even thought, gibberellins (GAs) are considered to be the main tuberization inhibitors, ST potato plants had surprisingly high GAs levels. The determination of tuber-inducing marker gene expressions...

Zhodnocení biologického potenciálu dřevin v lokalitě Senická třešňová alej
Ševčíková, Hana
Examined cherry alley is located in Senica (Trnava region, Slovakia). The main aim of this thesis was to register signs of presence of insects species at eight representative sample trees. Based on the results were suggested future interventions with emphasis on support of biodiversity. Notably significant was discovery of presence of cavity-specialised species – beetles of genus Oryctes and genus Cetonia. Based on this discovery was suggested relevant intervention. Surprising result was finding a very small amount of presence signs of genus Antaxia, which was highly expected. This might be caused by chemicals used in the agricultural enviroment nearby the alley.
