ABSTRACT
A rapid and accurate method was established by psbA-trnH sequence to distinguish Dioscorea nipponica from other species belonging to the same genus.In this study, we collected 144 samples of D. nipponica from 17 different producing areas in China, the psbA-trnH sequenced of 23 nucleotide sequences were downloaded from GenBank, the sequences from Dioscorea genus. DNAMAN 8.0 software was used to show splicing, MEGA 6.0 software was applied for sequence analysis and comparison. The results showed that the genetic relationship between D. nipponica and D. subcalva was the closest, and the genetic relationship with D. zingiberensis was the furthest. It is indicated that the psbA-trnH sequence as a DNA barcode can effectively distinguish between D. nipponica and other plants in the genus of Dioscorea.
