Vliv virových chorob na kvalitu hroznů révy vinné
Musilová, Eliška
The bachelors work was work out at Mendel University in Brno, Faculty of Horticulture in Lednice, at genetics institute in the course 2014 to 2016. The bachelors work is concerned with grapevines history (Vitis Vinifera) in our country, geographic, climatic conditions, sustance of grapevine and control of grapes quality. With this is related to virus diseases, which there was described. Their structure, classification, life cycle and progress of disease. It is itemize some examples of plant viruses which infest grapevine and it describe their symptoms of virus infection and effect to grapes and whole plant. In the last part are the most popular detection of viruses, methods of recovery to sick plants, their methods of succeses and written some examples.

Mitochondrial DNA diversity in populations of sub-Saharan Africa - role of language and geographic patterns
Musilová, Eliška ; Černý, Viktor (advisor) ; Brdička, Radim (referee)
To investigate relationships between genetic, linguistic, and geographic variation in Africa, we sequenced HVSI segment of mtDNA genome in 81 individuals of two West African populations from different linguistic families. These sequences were compared to similar data published by other authors. The interpopulation analysis included 4550 mtDNA HVSI sequences of 101 populations in total representing main African geographic and linguistic diversity. AMOVA indicates that the mtDNA among-group variation is higher when populations are grouped by geography (9,85 %; p < 0,001) than by linguistics (4,09 %; p < 0,001). Also MDS plotting based on FST data reveal a correlation between genetic and geographic distances and hardly any correlation between genetic and linguistic distances. The linguistic relation does not strenghten even if the most heterogenous language families (Niger-Congo, Khoisan) were removed from the analysis. These data suggest that complex patterns of diferentiation and gene flow in sub-Saharan Africa were influenced mainly by the admixture and language borrowing between expanding Bantu agriculturists and local hunter-gatherers in the last 3000 years, but the descent of some recent populational-genetic events can be traced in other parts of Africa.
