DNA条形码技术应用于人参鉴定
DNA Barcoding Used in the Identification of Ginseng.pdf
相似性搜索法是一种基于 BLAST搜索算法的鉴定
分析方法,来源于未知样品的 DNA条形码序列(query
sequence)与 DNA条形码数据库(referencelibrary)进行
比对,如果在 DNA条形码数据库中找到完全一样的序
列(referencesequence),那么未知样品就是该 reference
sequence对应的物种。对于人参鉴定而言,由于尚未有
正式的全球统一的 DNA条形码数据库,因此可直接将
条码序列与 GenBank数据库进行比对鉴定。
距离法是计算未知样品 DNA条形码序列(query
sequence)与数据库中每一个序列(referencesequence)
的遗传距离,未知样品应为具有最小平均遗传距离
(meandistance)的物种或者具有最小遗传距离(nearest
distance)的物种。Ross等建议使用 K2P模型用于条形
码计算,可采用 NeedlemanWunsch动态规划算法进行
全局比对,计算两两序列的 K2P距离,依据两种距离法
实施鉴定。
建树法是应用 MEGA或 PAUP等生物软件构建
NJ、UPGMA、MP等系统发育树,检验未知样品的 DNA
条 形 码 序 列 (querysequence)与 数 据 库 中 序 列
(referencesequence)聚类在一起的物种,根据聚类情
况进一步确定物种。Zuo等[26]
将测序所得人参属 DNA
条码序列用 PAUP4.0软件进行聚类分析,通过聚类树
准确地将属内物种区分开,实现了人参的条码方法

Although hundreds of medical plants have been sequenced, the related data were scattered at different sources, which hindered the systematical researches on medical plants. To solve such a challenge, we proposed the integrative database for Traditional Chinese Medicine Plant Genome (TCMPG). TCMPG not only deposits the genome data of traditional Chinese medical plants, but also provides a series of computational tools for researchers to perform systematical analysis. At present, 160 kinds of plants, 195 corresponding genomes, and 255 herbs (different parts from the same plant), together with the related information on plant species, genomes, and herbal medicines were included in TCMPG.
Moreover, the main genomic analysis tools, namely the BLAST to find orthologs from different plant, SSR Finder to identify SSRs, JBrowse to browse genomes, Synteny Viewer to display the syntenic blocks between two genomes, and HmmSearch to identify protein domain, were also embedded in TCMPG, which will facilitate the systematical analysis on medical plants. Once new data was reported, TCMPG will be updated and improved in time.
