Method for authentication Basmati type rice (Oryza sativa L.) using microsatellite length polymorphism: methodology for practice
Ovesná, Jaroslava ; Drábková, Lenka ; Kučera, Ladislav
The objective of the method is the proceudre how to identify traditional varieties of Basmati rice (TB) specified in the Implementing Regulation EU no. 706/2014 devoted to control laboratories in practice. This method enables to identify varieties exempt from duty in the EU. The test consists of microsatellite loci amplification by polymerase chain reaction (PCR) using specific primers, and subsequent analysis of the length of the products.

A simple method for detection of Czech bolting garlics (Allium sativum L.) using microsatellite analysis: methodology for practice
Ovesná, Jaroslava ; Mitrová, Katarína ; Kučera, Ladislav
The aim of the methodology was to verify and compile a set of microsatellite markers for the purpose of verification to be used for the undisputed identification of selected types of Czech bolting garlics. The object of submitted methodology is to simplify procedure that allow to determine Czech bolting garlic using microsatellite analysis (SSR- Single Sequence Repeats), which is applicable in testing laboratories. The described method allows to identify the variety and breeding material of bolting garlic of Czech origin using DNA markers (microsatellite alleles) that are present only for this group of varieties and breeding lines. By the amplification of the genome containing the microsatellite locus by polymerase chain reaction (PCR) using specific, fluorescently labeled primers, and subsequent analysis of the lengths of PCR products. Methodology newly brings a unique set of diagnostic SSR markers, describe the evaluation and interpretation of the results.

Methodology for detecting the presence of cranberries and lingonberries in processed products using molecular SSR markers: methodology for practice
Kučera, Ladislav ; Ovesná, Jaroslava
The subject of the methodology is a procedure for diagnosing the presence of lingonberries (Vaccinium vitis-idaea L.) and cranberries (Vaccinum macrocarpon L.) in processed products such as tea or fruit ingredients of many food products (jams, jelly, purree, tea). The methodology exploit DNA sequences that are typical for each plant species. Thus, molecular DNA markers that characterize the plant species by SSRs (single sequence repeats) are used. The methodology describes the extraction of DNA from the assumed matrix, the use of selected SSR markers and the analytical data evaluation procedure. The method can be used in any solid equipped molecular-genetic laboratory. The method is applicable for the characterization of DNA isolated from any part of the plant, fruit, and derived food or food supplements. Method describes the procedure and necessary equipment to perform the analysis. Protocol recommends how to evaluate the results.

Isolation and characterization of laccase gene in barley(Hordeum vulgare).
Drábková, Lenka ; Kučera, Ladislav (advisor) ; Čurn, Vladimír (referee) ; Fischer, Lukáš (referee)
Laccases are one of the oldest enzymes ever studied. For the first time laccase was mentioned by Yoshida in 1883 (Yoshida H, 1883). Laccases (EC, p-diphenol-O2 oxidoreductase), are copper-containing enzymes and are part of a larger group of enzymes termed polyphenol oxidase. Laccases catalyze oxidation of a broad range of substrates e.g., polyphenols, substituted phenols, diamines, but also some anorganic compounds with the concomitant reduction of oxygen to water. The source of electrons in these redox reactions are usually four copper atoms. Fungal laccases, so far the most extensively studied group, are known for their roles in lignin degradation, bioremediation, morphogenesis and pathogenicity. Despite many years of research, the physiological function of laccases in plants remains largely unknown. Plant laccase have been proposed to be involved in lignification. It participates mainly in the synthesis of lignin, maintenance of the cell wall integrity and structure and wound healing. Laccases can catalyze a wide variety of enzymatic reactions and apparently have a role in plants response to stress. Plant laccases have been described especially in Arabidopsis (Arabidopsis thaliana), corn (Zea mays), wheat and rice (Oryza sativa). Laccases have not been yet characterized in any others...
The sampling methodology for GM plants unintentionally present in the environment
Ovesná, Jaroslava ; Kučera, Ladislav ; Sovová, Tereza ; Mitrová, Katarína ; Pouchová, Vladimíra
In this methodology, sampling of plants from agricultural crops(corn, soybean, canola and potato) is defined to assess the presence of unauthorized GM plants in the environment.The methodology is applied mainly in the field of inspection controls of the compliance with Act no.78/2004. The sampling and collected samples must represent to a maximum extent the crops of the controlled part of the field (land parcel or land parcel portion). The basic applications of the methodology include:(a) low portion of unauthorized GM plants(seed contaminated with GM plants unauthorized for cultivation), (b) monitoring of the presence of unauthorized GM plants on land parcel, where there was such an occurence recorded in previous years (for example, plants growing on the field from seeds or tubers from the so called "soil´s seed bank").

Management and implementation of project procedure in educational system
Vrbová, Zuzana ; Švecová, Lenka (advisor) ; Kučera, Ladislav (referee)
In my final thesis I focus on process and implementation of project procedure. The main aim of this thesis is to show possibilities of how to work with projects in the nonprofit field of educational resort. The opening part is a summary of six chapters. I tried to summarize my own, as well as other theoretical knowledge and basic information concerning the branch of the project procedure, which are important for the following practical part of the thesis. I deal with individual phases of the project procedure, in which I explain terms such as project framework, the lifecycle of project, evaluation methods of projects, the use of information technology, risks that might appear in project procedure etc. Further in my thesis, which is very important, I focus on possibilities of project fundraising in schools. I present basic information about The European Business Academy in Decin, where I am employed. I also deal with options that teachers and students have to extend their education abroad, so called "the mobility of students and teachers". The main part of my thesis includes projects which are being prepared at The European Business Academy in Decin. As an example, I enclose a project which was conducted by students together with teachers and its implementation into use. The second project is a project objective which was not implemented. The third project is being processed and the fourth one has been approved. Another aim of my thesis is to show to other schools how to work with projects and give them a guideline how to involve not only teachers or other employees but also students. Since 2010 students of the final grade will create team projects and the process and defence of the project will be included in the final school-leaving examination.
