The role of DSE (Dark Septate Endophytes) in plant communities in forest ecosystem
Lukešová, Tereza
10 Abstract All plants live in symbiosis with fungal endophytes - they can form mutualistic, commensal or parasitic symbioses. Symbiosis of root endophytes, called for their darkly pigmented and septated hyphae dark septate endophytes (DSE), and plants has been often overlooked although its role for plant communities can be very important. Despite their ubiquitous presence in roots of terrestrial and also aquatic plants the influence of DSE on their host plants is still unresolved. Results of previous studies are inconsistent - some reported that DSE have positive effects on their host plant growth and some negative. The main reason for this inconsistency might be their complicated taxonomy and difficult identification of different cryptic species which are morphologically indistinguishable. We were able to complete a unique collection of the most common DSE species, mainly members of the Phialocephala fortinii - Acephala applanata species complex. The collection includes the most common DSE species isolated from roots of forest plant communities. The goal of my thesis was to describe behaviour of DSE in roots of typical forest plants and elucidate their physiological influence on host plants. In vitro resynthesis experiments were used to observe root colonization patterns. Nutrient flow between the plant...

Change of physical abilities of TSV Giesen Grizzlysw and VK ČEZ Karlovarsko players after condition training
Lukešová, Tereza ; Pokorný, Ladislav (advisor) ; Přibyl, Ivan (referee)
TITLE: Change of physical abilities of TSV Giesen Grizzlys and VK ČEZ Karlovarsko players after condition training AUTHOR: Bc. Tereza Lukešová DEPARTMENT: Department of Physical Education SUPERVISOR: PaedDr. Ladislav Pokorný ANNOTATION The work is focused on fitness training of volleyball players from two top men's competitions, and on the Czech Uniqa extraleague and the German Bundesliga. Work through testing of motor skills of twelve respondents from both teams. These were the tests: K-test, 200m sprint, trapeze, long jump, rebound reach range, reach, two-hand reach range. The first part of the thesis contains general information about volleyball literature and familiarization with movement abilities, with regard to work and work with them. The research part analyzes the already mentioned form of tests of motor abilities of the respondents before conditioning during the season, ie also in December. In conclusion, the results of this research and comparison with fitness training of the teams were evaluated. The work is intended mainly for advanced players or volleyball coaches. KEYWORDS: physical ability, voleyball, condition training

Language games in the teaching of Czech language on the first grade of the basic
LUKEŠOVÁ, Tereza
The thesis deals with linguistic games in the Czech language at the primary schools. The thesis is divided into two parts theoretical and practical. . The theoretical part focuses on the game and its benefits. Emphasis is put on the didactic game, its definition, classification, motivation, managemet and evaluation of the linguistic games. Theoretical part of the theses also deals with cooperative teaching and time undemanding cooperative methods. The practical part acquaints with the interpretation of the survey results. The survey was carried out by questionnaire. A fund of linguistic games applicable for the primary schools usage is part of the theses. These linguistic games were tried out and experienced.

Dark septate endophytes - ubiquitous root endophytes with still unexplored ecophysiological potential
Lukešová, Tereza ; Vohník, Martin (advisor) ; Kolaříková, Zuzana (referee)
5 Abstract In natural ecosystems, all plants coexist with fungi. This results in various plant-fungus symbioses, either mutualistic, parasitic or endophytic. For example, the mycorrhizal symbiosis is a mutualistic association that occurs in ca 70 to 90 % of all terrestrial higher plants. Probably even more widespread association is endophytism, when a fungus colonizes different living plant tissues without causing a strong plant defense response. This bachelor's thesis summarizes some older as well as recent papers and reviews on the ecophysiology of the most widespread root endophytes, the Dark Septate Endophytes (DSE), and their impacts on plants. DSE are ubiquitous root colonizers of terrestrial and aquatic plants. The most frequent DSEs isolated from the roots of different plants from Northern Hemisphere belong to the Phialocephala fortinii s.l. - Acephala applanata species complex (PAC). Although some of the PAC species are able to form ectomycorrhizal structures, most of them do not form any mycorrhiza-like structures in the root. Instead, they form inter- and intracellular microsclerotia and mostly melanised septate hyphae with thick cell walls. In contrast to the mycorrhizal symbiosis, DSE do not necessarily influence the host nutrient uptake, but they may play a role in plant drought, extreme...
