A novel satellite DNA sequence in the Peromyscus genome (PMSat): Evolution via copy number fluctuation

Popis výsledku v původním jazyce

Satellite DNAs (satDNA) are tandemly arrayed repeated sequences largely present in eukaryotic genomes, which play important roles in genome evolution and function, and therefore, their analysis is vital. Here, we describe the isolation of a novel satellite DNA family (PMSat) from the rodent Peromyscus eremicus (Cricetidae, Rodentia), which is located in pericentromeric regions and exhibits a typical satellite DNA genome organization. Orthologous PMSat sequences were isolated and characterized from threespecies belonging to Cricetidae: Cricetus cricetus, Phodopus sungorus and Microtus arvalis. In these species, PMSat is highly conserved, with the absence of fixed species-specific mutations. Strikingly, different numbers of copies of this sequence werefound among the species, suggesting evolution by copy number fluctuation. Repeat units of PMSat were also found in the Peromyscus maniculatus bairdii BioProject, but our results suggest that these repeat units are from genome regions outs
