Nobile. Results An about 300 bp DNA positive fragment was amplified from D. nobile with anneal temperature at 66 ℃ and anneal time at 40 s, whereas no any DNA fragment was amplified from the rest 39 species of Dendrobium Sw. 结果在66℃、40s的复性条件下进行鉴别PCR,金钗石斛的模板DNA扩增出约300bp的阳性扩增带,而其他39种石斛的模板DNA在同样条件下无扩增产物。
Methods Complete sequences of the mitochondrial nad 1 intron 2 for nine species of Dendrobium Sw. were amplified and determined. 方法扩增并测定9种石斛属植物线粒体中NADH脱氢酶亚基1编码基因(nad1)内含子2(intron2)的全长序列。
