Taxonomic characterization of Tanakia species (Acheilognathidae) using DNA barcoding analyses.

摘要: AbstractTanakia is a bitterling genus with six species found in Far East Asia. Our aim was to construct the standard DNA barcode database available for identification of Tanakia by comparing range intra- and inter-specific genetic distances, identifying phylogenetic placement each providing unique characteristics that are specific species, using cytochrome oxidase I (COI) b (cyt b). Both loci failed create perfect barcoding gap between ranges inter- intra-specific though interspecific COI distances were sufficiently greater than intraspecific values only few exceptions. In our analyses, T. koreensis signifer did not form monophyletic cluster haplotypes both loci. provided clear nucleotide distinguish whereas relatively fewer informative sites within cyt b. Overall, could be regarded as a...
