摘要：
The pBuM189 satellite DNA family was found to be species specific for Drosophila buzzatii. It consists of slightly AT-rich tandemly arranged repeats with a high copy number in the genome and shows a very high level of intraspecific sequence similarity. pBuM189 repeats cannot be detected in the genomes of closely related species such as Drosophila serido, Drosophila borborema and Drosophila koepferae. The data support the marginal systematic position of D. buzzatii within the buzzatii cluster of the Drosophila repleta group.
