Intersimple sequence repeats (ISSR) molecular fingerprinting markers have been employed to authenticate eight populations of Dendrobium officinale using 10 primers selected from 76 ISSR primers. A total of 127 DNA fragments were amplified, of which 115 were polymorphic (90.5% of all bands). Sixteen specific authentication markers have been found. To enhance the efficiency of authentication, ISSR fingerprinting codes have been constructed using six polymorphic bands for authenticating D. officinale populations. Eight wild populations of D. officinale have been authenticated accurately using ISSR.
利用从76个简单重复序列区间(ISSR)引物中筛选出的10个引物,通过ISSR分子指纹标记技术对8个铁皮石斛居群进行了鉴定。共扩增出127条DNA条带,其中115条具有多态性(占总条带数的90.5%)。已发现16个特异性鉴定标记。为提高鉴定效率,利用6条多态性条带构建了ISSR指纹编码,用于铁皮石斛居群的鉴定。利用ISSR技术准确鉴定了8个铁皮石斛野生居群。
