The results indicated that polymorphic variation of the regeneration plant was existed in molecular level 结果表明多年生黑麦草体细胞无性系在分子水平发生了多态性变异。

The somaclonal variation of regeneration plant derived from mature embryo of perennial ryegrass ( lolium perenne l . were analyzed with rapd makers 摘要以多年生黑麦草成熟胚诱导获得的再生植株为材料，利用rapd标记方法对其体细胞变异进行了研究。

T . identification of charactrization of transgenic mustard plants the putative transformant regeneration plants were assayed by pcr and pcr - southern blot analysis . both analysis the target bands were observed . so the integration of the cpti gene into mustard genome dna was confirmed . the result of insect - resistance showed that the transgenic plants are more resistant than non - transgenic plants 转基因芥菜植株的鉴定取再生苗的叶片提取dna ，进行pcr扩增和pcrsouthernblot分析，转化再生植株大部分呈阳性，而非转化的再生植株均为阴性，证明cpt基因已存在于芥菜基因组中。
