| 摘 要： | 采用优化的CTAB法提取宁杞1号和黑果枸杞的叶片基因组DNA,利用紫外分光光度计、琼脂糖凝胶电泳检测所得DNA的浓度和纯度,并进行PCR扩增。从101个引物中筛选出12个10 bp的随机引物对这两种枸杞的DNA样品进行RAPD扩增,共得到111条谱带,61条表现出多态性,多态性比率达54.95%。结果表明,宁杞1号与黑果枸杞的相似系数S=0.618,遗传距离D=0.382。

| Abstract: | The experiment optimized CTAB method to extractLycium barbarum L.NO.1and Lycium ruthenicum Murr.laminas genomic DNA.The concentration and purity of DNA were detected by UV spectrophotometer,agarose gel electrophoresis,and conducted a PCR amplification.12(10 bp)random primers were From 101 oligonucleotide primers on these two Lycium L.DNA samples amplified analysis,and 111 RAPD bands was detected,61 among which were polymorphic,the percent of polymorphic band was 54.95%.The results showed that the similarity... |
