Složení společenstev endoyfytických mikroorganismů osídlujících listy hemiparazitických rostlin
SVOBODOVÁ, Ilona
This bachelor´s thesis focuses on describing the community composition of endophytic microorganisms colonizing foliar parts of selected Central-Europaean species of parasitic plants and their potential hosts. The aim is to find specific differences in the structure and diversity of bacterial and fungal endophytes between plant species with parasitic and non-parasitic life strategy.
Effects of plants on the structure, function and diversity of bacterial communities
Havlíčková, Petra ; Baldrian, Petr (advisor) ; Kopecký, Jan (referee)
Vegetation is known to influence the composition of microbial communities. Bacteria can act as roots symbionts or be involved in the decomposition of plant biomass. They can be influenced by soil chemistry but also by plant exudates. Some plants produce targeted exudates to attract specific bacteria to their roots. Bacteria associate with plants frequently but the effect of plant diversity on bacterial communities on their roots and in the surrounding soil remains unclear. The aim of this work was to describe the relationship between the diversity and community composition of bacteria and the diversity of vegetation in forest and grassland ecosystems. The study areas were selected to represent a gradient of vegetation in Bohemian Forest NP and in White Carpathian flowery grasslands. I hypothesized that the diversity and evenness of bacterial community increase with increasing plant diversity. The composition of bacterial community was characterized by 16S rRNA sequencing. The composition of vegetation was determined by phytocenological relevées and by molecular markers trnL. In grassland ecosystem, there was a positive relationship between plant and bacterial diversity only in shoots. The space and vegetation were identified as an important drivers of bacterial community composition in shoots. The...
