Evoluce velikosti genomu v čeledi Costaceae / Genome size evolution in Costaceae

Genome size in plants varies greatly; in angiosperms this variability can make a 2400- fold difference. This is why the subject of many studies is the attempt to explain these differences in various contexts. One of these is the phylogenetic viewpoint, which studies the relationships between genome size and different taxonomic groups. Many studies have been published so far which explore the plants of the temperate zone; there are however very few studies investigating genome size in tropical plants. For this reason, the subject of this thesis is the analysis of genome size in the pantropical family Costaceae Nakai. This family presently includes seven genera: Monocostus K.Schum., Dimerocostus Kuntze, Costus L., Paracostus C.D.Specht, Chamaecostus C.D.Specht & D.W.Stev, Hellenia Retz. and Tapeinochilos Miq., counting altogether about 300 species. The family is sister to the family Zingiberaceae, which has been notably better explored due to its economic importance. One of the aims of this thesis was a partial revision of the phylogeny published by Specht (2006). Molecular methods were used to analyse the phylogenetic relationships; these methods included classical sequencing of the trnL-F region and next-generation sequencing, where probes designed in advance were used to obtain the targeted genes....
