Design of watering module for mobile robot
Vizváry, Peter ; Králík, Jan (referee) ; Krejsa, Jiří (advisor)
The diploma thesis is focused on the design of a watering module for a mobile robot. The main goals of this work are to design various concepts of the watering module and their subsequent comparison, ending with the selection of the final concept, which results in its implementation in the form of a prototype with subsequent testing of its properties. The first part of this work is focused on the analysis of the issue and the definition of the assigned task together with the main parameters and requirements. The second part contains an overview of known solutions to the issue and designs for own concepts of the watering module and its individual components. The designs are compared and evaluated in terms of their performance, complexity and price. In the third part, based on the evaluation of the most promising variants, there is a selection of the final concept and after that designing and selection of the final constructional solution. The fourth part is focused on the design and implementation of the prototype, contains the selection and design of the necessary components, module assembly and the creation of the control algorithm of the watering module. The final fifth part contains testing of the functional properties of the prototype, their evaluation and subsequent suggestions for its improvement.

The role of histone post-translational modifications in the regulation of gene expression in plants
Chromý, Jakub ; Čermák, Vojtěch (advisor) ; Holá, Dana (referee)
Chromatin structure, gene expression and consequently many important aspects of the plant development are under control of epigenetic regulation. Within epigenetic regulation, histones and their modifications play a pivotal role. The N-terminal tails of histones are dynamically modified by covalent post-translational modifications (PTMs). These modifications are key regulators modulating chromatin structure and thus regulating gene expression. In angiosperms, one of the processes finely regulated at the epigenetic level is the flowering. Flowering represents a very complex process, that is relevant for the study of epigenetic regulation as well as for practical application. In this work, I summarize current knowledge of the role of histone PTMs in the regulation of gene expression in plants, focused predominantly on two key regulators of flowering in Arabidopsis - FLC and FT.
