摘 要:目的 在兰科石斛属药用植物鉴定中应用新的分子标记。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。结果 比对后的nad1intron2序列长872
bp,其中有17个变异位点,可以鉴别除粉花石斛Dendrobiumloddigesii以外的8种植物。结论线粒体nad1in—
tron2序列可以作为一种新的分子标记用于石斛属植物的鉴定。

摘要:目的研究野生天麻总DNA对马铃薯的转化,分析马铃薯转化植株中野生天麻的药用成分天麻素。方法
采用浸苗法将野生天麻总DNA导人马铃薯试管苗,通过紫外扫描法、PCR扩增筛选转化植株,对转化植株进行
SDS一聚丙烯酰胺凝胶电泳(SDS—PAGE)蛋白分析,通过TLC法检测天麻素。结果(1)在200株转化的马铃薯中
有21株的紫外扫描图谱与正常对照组有显著差异,且在220nm有明显吸收峰。(2)5’株经PCR扩增出野生天麻抗
真菌蛋白(GAFP)基因。(3)转基因马铃薯与正常马铃薯的蛋白表达有明显差异,并且在转基因马铃薯中有一条与
GAFP相同的条带。而正常马铃薯中无此条带。(4)通过薄层色谱法检测出3株转基因马铃薯表达野生天麻的有效
药用成分天麻素。结论 采用浸苗法进行外源总DNA导入是可行的。
