ALBA-family proteins and their role in male gametophyte development
Náprstková, Alena ; Honys, David (advisor) ; Rothová, Olga (referee)
Alba family proteins are highly conserved in all domains of life. They are involved in RNA metabolism in Archae and Eucarya, while they are involved in the chromatin organisation in Crenarchaea. In animals, ALBA proteins were identified to associate with RNase P/MRP subunits. The objective of my thesis was the characterization of ALBA family proteins in a model plant Arabidopsis thaliana. The Arabidopsis genome contains six genes with close homology, three from Rpp20-like subfamily and three of Rpp25-like subfamily. Here I present the localization of GFP-fused proteins in Arabidopsis stable lines harbouring constructs cloned by Gateway® Technology. ALBA proteins were localized in the cytoplasm and undefined particles in root differentiation zone and in mature pollen. The characterization of the respective T-DNA insertion lines did not reveal significant phenotype defects in growth and development of sporophyte and gametophyte in comparison to Columbia-0 plants, probably because of likely functional redundancy od the paralogs. Expression profiles and localization of ALBA proteins suggest their possible role in differentiation and dehydration stress response in Oryza. They were also observed to associate with repressed mRNA transcripts in storage EPP particles. Collectively, I propose the likely role...

UNASUR - analysis of the Southamerican integration
ŠPITÁLSKÁ, Iveta
The objective of this bachelor thesis is to clarify the process of integration in the region known as Latin America. In Part 2:- Theory, I define borders and analyze the origin of the term "Latin America". I also deal with the theories of terms related to the topic. In the following section, I analyze the historical development of integration, while exploring the influence of the United States´ tendency to integrate into Latin America. The main subject of analysis is the organization UNASUR. I will try to illustrate its institutional structure, goals, and successful projects.

Venezuela na přelomu tisíciletí
Šanda, Milan ; Adamcová, Lenka (advisor) ; Nováček, Jan (referee)
Práce analyzuje současnou politicko-ekonomickou situaci Bolívarovské republiky Venezuela. Širší záběr osvětluje politický vývoj v zemi od poloviny 20. století, nosným obdobím je však situace od druhé poloviny devadesátých let do současnosti. Instrumentem k charakteristice tohoto období je SWOT analýza slabých a silných stránek a následná načrtnutí možných příležitostí a hrozeb determinovaných jak současným stavem tak vnějšími vlivy působícími na tuto latinskoamerickou ropnou ekonomiku.

Integration processes in Latin America (political and cultural assumptions and implications)
Jeníčková, Martina ; Lehmannová, Zuzana (advisor) ; Kochan, Jan (referee)
Diplomová práce se zabývá integračními procesy v Latinské Americe s důrazem na období od začátku 90. let 20. století, kdy dochází k oživení integračních snah. Zkoumá souvislosti mezi ekonomickou, politickou a kulturní dimenzí integrace. Poukazuje na určitý posun v charakteru integrace od 90. let minulého století a také na některé nové trendy. V první části stanovuje východiska k problematice. V druhé části zkoumá integraci ze subregionálního hlediska. V třetí části se zabývá celoregionálními iniciativami. Práce rovněž naznačuje vliv USA na latinskoamerickou integraci.
