Název v původním jazyce

Detection of genetically divergent clone mates in apomictic dandelions.

Popis výsledku v původním jazyce

This study aims to identify genetically diverged clone mates in apomictic dandelions. Clone mates are defined as individuals that may have diverged as a result of mutation accumulation and that have undergone only clonal reproduction since their most recent common ancestor. Based on distinctive morphology and an aberrant and rare chloroplast haplotype, northwest European individuals of Taraxacum section Naevosa are well suited for the detection of clonal lineages in which mutation has occurred. In the case of strictly clonal reproduction, nuclear genetic variability was expected to be hierarchically organized. Nucleotide polymorphisms in internal transcribed spacer (ITS) sequences, however, were incompatible with a clonal structure of the Norwegian individuals, probably due to persistent ancestral polymorphisms that pre-date the origin of the Naevosa clone. This interpretation is supported by the presence of ITS variants in section Naevosa that were also found in distantly related dand
