摘要 DNA条形码( DNA Barcoding )技术是一种新的物种识别方法,它是分子生物学和生物信息学相结合的产物。在最近几年里,该技术已成为生物分类学中引人注目的研究热点。这一概念认为,类似于商店里使用扫描仪读取条形码,对地球上每一种生物通过快速分析其DNA中的一段基因(线粒体细胞色素c氧化酶Ⅰ亚基, mt COⅠ)加以识别。理论上, DNA条形码已被证明在生物分类鉴定中具有非常重要的作用,并推动了一系列相关学科的发展,但目前不同分类学家对其持的意见也不尽相同。本文综述了DNA条形码技术的产生、发展概况、原理与操作及其在分类中的应用,并概括了DNA条形码在应用于物种分类中可能存在的问题。 DNA barcodes technology is a new species identification methods , it is the combination of molecular biology and bioinformatics.In recent years, the technology has become a compelling focus of taxonomy research .In theory, DNA barcodes have been shown to have a very important role in the taxonomic identification, and to promote the development of a series of related disciplines, but different taxonomists hold different views. This paper reviews the origins , the development, operating principles and application of DNA barcode in classification, and outlines the possible problem of DNA barcodes in species classification.
