Abstract/OtherAbstract:
Comparative genomics is a powerful approach to inference of the dynamics of genome evolution. Most information about the evolution of microsatellites in the genus Drosophila has been obtained from Drosophila melanogaster. For comparison, we collected microsatellite data for the distantly related species Drosophila virilis. Screening about 0.5 Mb of nonredundant genomic sequence from GenBank, we identified 239 dinucleotide microsatellites. On average, D. virilis dinucleotides were significantly longer than D. melanogaster microsatellites (7.69 repeats vs. 6.75 repeats). Similarly, direct cloning of microsatellites resulted in a higher mean repeat number in D. virilis than in D. melanogaster (12.7 repeats vs. 12.2 repeats). Characterization of 11 microsatellite loci mapping to division 40-49 on the fourth chromosome of D. virilis indicated that D. virilis microsatellites are more variable than those of D. melanogaster.
