Genotypic diversity of apomictic microspecies of the Taraxacum scanicum group (Taraxacum sect. Erythrosperma)

Popis výsledku v původním jazyce

Populations of polyploid apomictic dandelions consist of a mixture of clonal genotypes that are nearly phenotypically and genetically uniform. Some apomictic taxa are widespread, but many other taxa occur locally or at a single locality. Additionally, certain Central European dandelion populations consist of both diploid sexuals and polyploid apomicts, and the gene flow expected in mixed populations obscures clear genetic and morphological borders among apomictic taxa. In the present study, we investigated genotypic diversity among seven apomictic microspecies coexisting in Central Europe. Using microsatellites, amplified fragment length polymorphism and chloroplast DNA markers, we focused on the clonal structure of apomictic taxa, i.e., whether the studied apomictic taxa are represented by one or a few related genotypes or whether they are represented by many different and unrelated genotypes. The pattern of genotypic diversity within the studied microspecies suggests both intra- and
