Root - shoot junction (collet) development
Hermann, Jiří ; Žárský, Viktor (advisor) ; Tylová, Edita (referee)
Although the root-shoot junction (collet) of adult plants is a well-identifiable part of the plant body, its development has, surprisingly till now, escaped serious research attention. The junction is a key region in the life of plants, as it connects two contrasting plant life environments and involves important changes in developmental programs - underground vs aboveground. The junction in angiosperms is first established during the embryogenesis phase of development in the form of the broad embryonic root- hypocotyl transition region, and it continues to develop further after seed germination during the individual's growth. The most important organ in this process is the hypocotyl, which exhibits considerable developmental plasticity, allowing extraordinary elongation in etiolated dark growth but also initiating formation of adventitious roots upon the deetiolation. During each stage of the junction's development, auxin signalling and polar auxin transport play a crucial role. Most of the research focuses on the development of the junction in the model organism Arabidopsis thaliana. The significance of the phylogenetic origin of the junction is also discussed from the perspective of the evolutionary origin of roots vs shoots and embryos evolution. This work aims to provide an overview of the...

Law of Lien
Hermann, Jiří
Disseration thesis - Law of Lien Mgr. Jiří Hermann Law of Lien is basic form of security interest which importance is proved by long term tradition. During time the Law of Lien was modified which reflected economic development which result to the current modern state. Even if legal regulations of Lien are different with respect to the concrete developmentu in each state, its basic principles, functions and its meritum are same for the centuries. Importance of the Law of Lien as security interest is emphasized namely by high level of security which is given to the Lien Creditor. Because of this reason is Lien one form the most used legal security interests in worldwide respect. The Objective of Thesis is to summarize the very wide and complicated regulation of Lien and suggest de lege ferenda new regulation which makes the institutes more clear and increase the security of the Creditor. The theme of thesis is very wide. In respect to volume of relevant institutes is conception of the thesis as complex view on Lien as the security instrument. The Thesis shall explain with principles of Lien and raise the problematic topic. In several cases is regulation of Lien unclear which cause the application troubles. The thesis is pointing out such topics and suggests possible solution, which is in accordance...
