Satellite DNA as a phylogenetic marker: Case study of three genera of the murine subfamily

Satellite DNA (satDNA) represent tens of percent of the vertebrate genome. However, no full set of satDNA fragments has been determined for even one species. It is known that some genera possess a satDNA characteristic for that genus with species-specific modifications. We found that the pattern of...

Description
Summary:Satellite DNA (satDNA) represent tens of percent of the vertebrate genome. However, no full set of satDNA fragments has been determined for even one species. It is known that some genera possess a satDNA characteristic for that genus with species-specific modifications. We found that the pattern of hybridization of Mus musculus satDNA probes with M. spicilegus metaphase chromosomes was similar to, with slight differences from, that of M. musculus. No hybridization signal was observed if Mus musculus satDNA probes were hybridized with representatives of Sylvaemus and Apodemus genera. The amount of Mus musculus satDNA in the genomes of various species was evaluated by dot-hybridization. We revealed that genomes of close murine species had cenromeric and pericentromeric repeats belonging to the same families and were not found in remote species.
