| 摘 要： | 目的:研究菊苣再生植株的遗传稳定性.方法:以菊苣叶片为外植体,经第一代和第二代体细胞再生获得再生植株,分别对再生植株提取DNA,从12个引物中筛选了2个多态性好的引物,对第一代和第二代体细胞再生植株进行RAPD标记.结果:菊苣第一代体细胞无性系没有发生DNA多态性变异,第二代体细胞无性系在分子水平发生了1条DNA多态性变异.结论:RAPD分子标记方法可以鉴定菊苣组织培养过程中的遗传稳定性和遗传变异,为菊苣快繁和遗传转化奠定了基础.

| Abstract: | Objective: To research the genetic stability of regenerated plants of chicory(Chicory intybus/ L.).Method: Young leave of chicory plantlet in vitro was used as explants to induct regenerated plants by the first regeneration and the second filial regeneration.The DNA of the first regeneration and the second filial regeneration plants were extracted.2 good polymorphism primers were bolted from 12 primers,and the genetic stability of regenerated plants were analyzed with Randomly Amplified Polymorphic DNA(RAPD... |
