Abstract
We have analyzed the genome of central Indian swamp deer Cervus duvauceli branderi, an inhabitant of the Kanha National Park, a wildlife conservatory in Central India, with a view to provide a genetic basis for their extinction. Evolutionarily conserved repeat sequence motifs (GATA)3.75, TA(GATA)4, (GACA)3.75, (TGG)6 and a set of mouse beta-actin primers were used to uncover the sequence variation within and between related species by employing techniques of hybridization and AP-PCR amplification. The oligo probe carrying the GACA and TGG repeat motifs was found to be positive with Cervus genome, whereas (GATA)3.75, TA(GATA)4 and beta-actin probes did not cross-hybridize with the same. AP-PCR amplification with (GACA)3.75, unlike the (TGG)6 primer, generated distinct bands in the range of 0. 37-2.10kb amongst different genomes including Cervus. A comparative genome analysis of other species using the AP-PCR approach with (GACA)3.75 primer revealed the phylogenetic status of Cervus duvauceli branderi. From the analysis of a very limited number of Cervus DNA samples, we observed a high level of genetic homogeneity that may be a prime reason for the extinction of this species. This study has implications in the context of conservation of this endangered Cervus duvauceli branderi species.
