Abstract
本发明的目的是提供一种基于原位PCR技术简便、快捷克隆植物基因的方法。本发明基于原位PCR技术,采用碱溶液与表面活性剂混合作为裂解液,比较了两种碱溶液和三种表面活性剂的裂解效果,从中选出了一种最佳的裂解液条件。相比传统PCR技术通过CTAB法和SDS法的繁琐步骤去除细胞内蛋白、多糖、RNA、盐类等杂质,提纯DNA或RNA进行扩增,程序复杂、耗时长,每次提取DNA时都需要大量实验材料与接触有害试剂,无法减少耗材与人力资源,且在提取过程中会造成DNA的损伤。本研究所用的方法无需提DNA或RNA,使用少量烟草叶片与常见实验试剂,即可短时高效裂解烟草叶片内表面细胞壁,使DNA分子裸露,为分子生物学提供了简便、快捷的提取方法,更为经济、高效。
