Název v původním jazyce

Chromosome analysis and sorting in Vicia sativa using flow cytometry

Popis výsledku v původním jazyce

Procedures were developed for flow cytometric analysis and sorting of mitotic chromosomes (flow cytogenetics) of common vetch (Vicia sativa L., 2n=12). Suspensions of intact chromosomes were prepared from root tips after cell cycle synchronization, formaldehyde fixation, and mechanical homogenization. On average, 3 x 105 morphologically intact chromosomes could be isolated from 25 root tips. Flow cytometric analysis of DAPI-stained chromosomes resulted in histograms of relative fluorescence intensity (flow karyotypes) containing four peaks, representing particular chromosomes and/or pairs of chromosomes with similar relative DNA content. Peaks I and II were assigned to chromosomes 6 and 5, respectively. These chromosomes could be sorted with a purity exceeding 90 %. The two remaining peaks on the flow karyotype were composite, each of them representing a pair of chromosomes. Chromosomes 1 and 3 were assigned to composite peak III while chromosomes 2 and 4 were assigned to composite pea
