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.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 biodiversity conservation and economic development in China lend the urgency to application of DNA barcoding in biodiversity conservation.DNA barcoding s.l.has been proved usefulness in identifying Chinese herbal medicine.
