| 摘 要： | DNA条形码技术是指传统分类对物种无法鉴定时,运用一条短的标准的DNA区间作为条码来进行物种鉴定的方法.目前,叶绿体基因rbcL和matK基因片断可能被用作植物DNA条形码技术的分子标记.本文回顾了DNA条形码技术的背景,植物DNA条形码技术的过程和效果.广义DNA条形码技术已被证实在中药鉴定中具有作用.同时,本文还讨论了在我国经济高速发展时期,DNA条形码技术在生物多样性保护中应用前景.

| Abstract: | DNA barcoding is a diagnostic technique for species identification,using a short standard region of DNA as bar code,with the aim of contributing to a wide range of ecological and conservation studies in which traditional taxonomic identification is not practical.In particular,the chloroplast genes rbcL and matK have been employed as a possible DNA marker for plant species.Here,we review the roots of DNA barcoding,plant DNA barcoding process and efficacy.In addition we discuss that the conflict result from b... |
