DNA 条形码技术在木通不同种质鉴别中的应用摘要;条形码技术是为实现对信息的自动扫描而设计的,它在零售业的发展过程中起到了重要作用,节省了交易时间,提高了销售效率。随着分子生物学技术和生物信息学的发展,基于 DNA 技术进行鉴定和分类的研究已成为生物分类学研究中引人注目的新方向和研究热点。关于 DNAbarcoding 的大量报道见诸于相关学术刊物和其他媒体上,如Science_1I2],Nature ],PNAS_5I6],The NewYork Times¨, National Geographic News 等。生物条形码协会(Consortium for the Barcode of Life)已有 40 个国家的 130 多个研究单位参与其中 。生物条形码网站http://www、barcodinglife.con,真菌编码网站 ht.tp://www.allfungi.org/,鳞翅目编码网站 http://www.lepbarcoding.org/,鱼类编码网站 http://www.fishbo1.org/等网站相继建立,2007 年 5 月 10 日,世界上第一个 DNA barcoding 鉴定中心在加拿大 University ofGuelph 成立 。本文综述了 DNA barcoding 技术的研究现状,并就该技术在中药材鉴定中应用的技术方法、技术路线、关键问题以及应用范围等方面开展研究进行了论述,为建立中药材 DNA barcoding 鉴定技术奠定基础 Abstract; bar code technology (Barcode techniques) is designed to realize the automatic scanning of information, it is in the development of retail industry played an important role in the process, save transaction time, improve sales efficiency. With the development of molecular biology and bioinformatics, identification and classification based on DNA bar.coding technology has become a new research direction and hotspot in the field of biological taxonomy. A large number of reported about DNAbarcoding in the relevant academic journals and other media, such as Science_1I2], Nature, PNAS_5I6], The NewYork National Geographic News Times ", etc.. The Barcode (Consortium for the of Life) has been involved in more than and 130 research institutes in 40 countries. Bio barcode website http: / / www, barcodinglife.con, fungi ...
