| Abstract: | 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. |
