Genome-wide analysis of tandem repeats in Daphnia pulex--a comparative approach.

ABSTRACT:

Background

DNA tandem repeats (TRs) are not just popular molecular markers, but are also important genomic elements from an evolutionary and functional perspective. For various genomes, the densities of short TR types were shown to differ strongly among different taxa and genomic regions. In this study we analysed the TR characteristics in the genomes of Daphnia pulex and 11 other eukaryotic species. Characteristics of TRs in different genomic regions and among different strands are compared in details for D. pulex and the two model insects Apis mellifera and Drosophila melanogaster.

Results

Profound differences in TR characteristics were found among all 12 genomes compared in this study. In D. pulex, the genomic density of TRs was low compared to the arthropod species D. me
