摘要:

生物DNA条形码已成为近年来生物学研究的热点,该技术在动物研究中已得到广泛应用,在植物中研究进展缓慢,植物DNA条形码筛选区域主要集中在叶绿体和核糖体内转录间隔区(ITS),目前还未获得广泛认同的植物DNA条形码。本文主要综述了不同单片段条形码及组合条形码的研究及应用现状,并展望了植物DNA条形码应用前景。

Abstract:

DNA barcode of life has become one of hotspots of biology research in the recent years.DNA barcoding is now well established for animals.However,DNA barcoding in plants is going on slowly.And the search for an analogous region to plant has focused on chloroplast DNA and the internal transcribed spacers of nuclear ribosomal.The quest for a universal DNA barcode in plants is still disputed.In this paper,the advance of these barcoding regions and their combinations are reviwed,the advantages,criterion,drawbacks,existed dispute,and the prospect of application of DNA barcoding in plant are summaried.
