摘  要:
PCR技术广泛用于分子标记、基因工程等领域,是植物系统发育及种群遗传结构等研究的基础。通过对影响PCR体系扩增的主要因子进行单因素试验,得出南方红豆杉(Taxus chinensis var.mairei)叶绿体DNA(cpDNA)最优体系(30μL)为3μL 10×PCR buffer,1μLDNA模板(60 ng),4.2μL MgCl_2(3.5 m M),8.4μLdNTPs(0.7 m M),0.9μL引物(0.3μM),0.8μL Taq DNA聚合酶(2 U),10.8μL去离子水。利用该体系筛选出叶绿体DNA非编码区通用引物4对,分别为atp I-atp H、psb J-pet A、trn H-psb A和trn L-trn F。

摘  要:
PCR was used widely in fields of molecular markers and gene engineering,which was the basis of research on plant phylogeny and genetic structure of populations. The optimal cp DNA- PCR reaction system of Taxus chinensis var. mairei was established containing 3 μL 10 × PCR buffer,1 μL template DNA( 60 ng),4. 2 μL MgCl_2( 3. 5 m M),8. 4 μL d NTPs( 0. 7 m M),0. 9 μL primers( 0. 3μM),0. 8 μL Taq DNA polymerase( 2 U) and 10. 8 μL dd H_2O in a total volume of 30 μL reaction system by single factor test of main factors influencing PCR system amplification. Using this system,4 pairs of cp DNA noncoding primers which were atp I- atp H,psb J- pet A,trn H- psb A and trn L- trn F were selected.
