摘要:
为了快速获取高质量的藜麦基因组DNA,采用改良的CTAB法、SDS法和高盐低pH值法等3种方法分别提取藜麦不同组织(叶、茎、根部)的基因组DNA。通过琼脂糖凝胶电泳和紫外分光光度法测定比较所提DNA的质量和产量,同时进行了PCR-SSR、SSCP等分子检测。用不同方法提取藜麦不同组织部位DNA的结果表明:不同提取方法的凝胶检测条带均比较清晰,且无明显降解;改良的CTAB法所提取的DNA产率最高,SDS法其次,而高盐低pH值法最低;不同方法提取的叶片DNA产率均明显高于根部和茎部;改良的CTAB法和高盐低pH值法所提取的DNA质量较好,多酚类化合物和多糖等杂质去除得比较完全。PCR-SSR和SSCP检测结果表明:不同方法和不同组织所提取的DNA均能跑出良好的条带,适合进行后续的分子生物学研究。
