title: PCR-SSCP and sequence analysis of three Odontotermes spp. (order: isoptera; family: termitidae) on the basis of partial 16SrRNA gene.
abstract: Partial 16S gene fragments were amplified by using specific primers in few species/populations of termites of the genus Odontotermes (Isoptera:Termitidae:Macrotermitinae), and the PCR products were subjected to SSCP analysis. Three haplotypes obtained were subjected to sequencing. The sequences obtained were characterized to see the frequencies of each nucleotide bases. High A + T content was observed. The inter-specific pairwise sequence divergence in Odontotermes spp. ranged from 0% to 4.8% across the entire 16S gene fragment. Identical sequences were found between two populations of O. horni. Individuals of different species having Type-I conformational pattern, i.e. O. obesus (-AI) and O. horni (-MI), as well as Type-II of O. obesus (-UII) and O. bhagwatii (-CHII) had no percent diversity. Phylogenetic trees drawn on the basis of distance Neighbour-joining method revealed clustering of individuals according to their genera and families.
