DNA条形码技术在木通不同种质鉴别中的应用

Abstract;bar code technology (Barcode techniques)is designed torealize the automatic scanning of information,it is in thedevelopment of retail industry played an important role in theprocess,save transaction time,improve sales efficiency.With thedevelopment of molecular biology and bioinformatics,identificationand classification based on DNA bar.coding technology has become anew research direction and hotspot in the field of biologicaltaxonomy.A large number of reported about DNAbarcoding in therelevant academic journals and other media,such as Science 112],Nature,PNAS_516],The NewYork National Geographic News Times",etc..The Barcode (Consortium for the of Life)has been involved in morethan and 130 research institutes in 40 countries.Bio barcode websitehttp:/www,barcodinglife.con,fungi encoding website ht.tp:www.allfungi.org /Lepidoptera encoding site http:/www.lepbarcoding.org fish,encoding website http:/www.fishbol.org other sites have been established,in May 10,2007,the world's first DNA barcoding identification center wasestablished in Canada University ofGuelph.This paper summarized theresearch status of DNA barcoding technology,technical method,andthat the technique in identification of Chinese herbs applicationkey technical route,and the application scope of the research arediscussed,which lays the foundation for the establishment of Chineseherbal medicine DNA barcoding identification technology
