Abstract
Regular monitoring and comprehensive study of natural populations rare endangered species, both by classical taxonomy and molecular genetic analysis methods are of considerable importance all over the world. This work has focused at the research of species diversity flora of Uzbekistan using combinations of DNA markers. Currently, there are no universal DNA site for plant species identification. Pairwise sequence alignments and multiple sequence alignments are made using ClustalW program. DNA sequence data were used to verify the taxonomic identity and phylogenetic aspects of the studied representatives the tribe Mentheae (Lamiaceae) collected in Uzbekistan territory. The phylogenetic analyzes of this tribe was reconstructed for 44 species, representing 19 genera using nuclear ribosomal DNA internal transcribed spacer region (nrITS), containing ITS1 and ITS4 adopted as an important basis, since it can provide a high resolution of relationships. 15 consensus ITS gene sequences were obtained for studied species in this work and 29 published molecular sequence data from GenBank were used. Dendrograms were constructed using hierarchical clustering with the software Mega X. The parsimony analyses were resulted in an accurate consensus tree. Three major clades was identified within the tribe Mentheae. So, this paper demonstrates the successfully usefulness of DNA technology as a tool for genetic inventory at the species diversity assessment of rare endangered plants.
