Studium polymorfizmu DNA mrkve
Sejbalová, Darina
This work is focused on theoretical and practical study of genetic diversity in carrots species. The aim of this work was to analyze the DNA polymorphism in Daucus carota L. by using molecular biology methods based on DNA isolation, PCR and electrophoretic separation. A total of 20 samples were analyzed by using 10 microsatellite markers. It was detected a 50 alleles with an average of five alleles per locus and alleles size between 180 and 380 bp. Further were calculated statistical parameters DI, PI and PIC, which confirmed the high value of polymorphism of used SSR markers. Dendrogram was compiled, identifying the relationships between different varieties of carrots. The results were compared with scientific publications dealing with the same or very similar problems.

Methodology for detecting the presence of cranberries and lingonberries in processed products using molecular SSR markers: methodology for practice
Kučera, Ladislav ; Ovesná, Jaroslava
The subject of the methodology is a procedure for diagnosing the presence of lingonberries (Vaccinium vitis-idaea L.) and cranberries (Vaccinum macrocarpon L.) in processed products such as tea or fruit ingredients of many food products (jams, jelly, purree, tea). The methodology exploit DNA sequences that are typical for each plant species. Thus, molecular DNA markers that characterize the plant species by SSRs (single sequence repeats) are used. The methodology describes the extraction of DNA from the assumed matrix, the use of selected SSR markers and the analytical data evaluation procedure. The method can be used in any solid equipped molecular-genetic laboratory. The method is applicable for the characterization of DNA isolated from any part of the plant, fruit, and derived food or food supplements. Method describes the procedure and necessary equipment to perform the analysis. Protocol recommends how to evaluate the results.
