| 摘 要： | 利用离子束介导法将玉米（郑单14）DNA片段转入水稻豫粳6号，经过5年的筛选得到了基本稳定遗传的变异株系。本研究通过对64对AFLP选扩引物的筛选，优选出了18对选扩引物，它们能同时在2个变异株系中扩增出大量的DNA指纹条带，并且同时能扩增出差异带以及“目的带”。用AFLP分子标记初步分析了2个变异株系与对照间的差异，变异株系中出现了新带、缺失带和“目的带”等几种情况，这些DNA水平上的差异，表明离子束介导玉米DNA育成的水稻材料可能已经插入了玉米的DNA。

| Abstract: | Many stable heritable rice lines were obtained via five years agricultural selection,which were derived from rice(Oryza stative Japonica)Yujing-6 transgened with large fraction DNA of Zhengdan-14(zea mays L.)by particle beam method.18 pairs optimum selective primers were got by screening from 64 pairs AFLP selective primers via experiment on two mutant lines,which could amplify many DNA fingerprints and also could amplify polymorphic bands and target bands,both in this two mutant lines.Then the two mutant l... |
