Comparison of highly repeated DNA sequences in some Lemuridae and taxonomic implications.
Highly repeated DNA sequences of Eulemur fulvus mayottensis, E. coronatus, Lemur catta, and Hapalemur griseus griseus have been identified and compared. Sequence analysis of highly repeated DNA fragments isolated from L. catta and Hapalemur showed a high percentage of similarity (nearly 95%), as did fragments isolated from the two very close Eulemur species, whereas comparison of the DNA fragments isolated from the two Eulemur species and the L. catta/Hapalemur group showed a very low percentage (approximately 40%) of identity, as might be expected for distant species. These results confirm our previous data, obtained by Southern blot hybridization techniques on the same species, and strongly support the existence of a common trunk between L. catta and Hapalemur, but different from the leading to the Eulemur species.
