| 摘 要： | 从掌叶半夏(Pinellia pedatisecta Schott)块茎中提取总RNA,反转录合成cDNA.根据GenBank中已报道的天南星科凝集素基因序列,设计带有酶切位点的表达引物,用RT-PCR方法扩增出掌叶半夏凝集素(Pinellia pedatisecta agglutinin,PPA)基因.PPA经双酶切后与表达载体pGEX-6P-3连接,构建pGEX-PPA重组表达载体.通过PCR、双酶切及测序鉴定,结果表明,重组载体pGEX-PPA构建成功,为进一步进行PPA的原核表达及其功能研究奠定了基础.

| Abstract: | Total RNA extracted from tubers of Pinellia pedatisecta was reversely transcribed into cDNA and a pair of specific primers with restriction enzyme sites were designed according to the reported sequences of agglutinin genes from Arisaema.The Pinellia pedatisecta agglutinin(PPA) gene was amplified by RT-PCR using cDNA as the template.The digested PPA was inserted into pGEX-6P-3 and the recombination vector pGEX-PPA was established.The recombination vector pGEX-PPA was identified by PCR,restriction enzyme dige... |
