摘要: 本研究根据GenBank发表的哺乳类SRY核酸序列和禽类EcoR I家族序列设计1对引物,对中国林蛙真伪品进行了PCR扩增,并对特征条带进行了克隆测序。结果表明,PCR扩增产物有明显的区别,中国林蛙、黑龙江林蛙、黑斑蛙和中华大蟾蜍分别扩增出约1000、250、450、750 bp的特征条带,通过对中国林蛙1000 bp条带的克隆序列进行BLAST比对分析,找到了一些禽类的WZ染色体上的相关基因片段。

Abstract: In this study, one pairs of primers was designed and synthesized according to the sequence of Mammalia SRY nucleic acid and bird EcoR I published on GenBank, to amplify the true or false of Rana Chensinensis by the PCR technique. As a result, the amplified products of the four species had apparent difference. The four species named Rana Chensinensis, Rana amureansis, Rana nigromaculata and Buffo bufo gargarizans amplified four different characteristic spectrum bands separately 1000,250,450 and 750 bp,and to test the sequence by colon about characteristic spectrum band. To take BLAST analysis about Rana Chensinensis’s characteristic spectrum band(1000 bp), and discovered relative gene fragment on WZ chromosome of some birds.

Key words: Rana Chensinensis; PCR discrimination
