- 摘要:
- 以番石榴为试材,采用CTAB、SDS和改良的CTAB法分别从新鲜的番石榴叶片中提取DNA,并对其进行琼脂糖凝胶电泳检测和SCoT-PCR分析。结果表明:3种方法均可以从番石榴的叶片中提取DNA,但改良的CTAB方法通过加入漂洗液2次洗涤,能够较好的去除样品中的多酚、多糖和蛋白质等物质,可以较好的从新鲜的叶片中提取较高质量的DNA,并可以用于SCoT-PCR标记分析。
- Abstract:
- Taking Psidium guajava as material,total DNA was extracted from fresh Psidium guajava leaves by CTAB,SDS and improved CTAB method respectively,and it was detected by agarose gel electrophoresis and SCoT-PCR marker analysis.The results showed that the above three methods were available for DNA extraction from Psidium guajava leaf,but improved CTAB method by adding rinse and two times washing,could effectively remove polyphenols,polysaccharides,protein and other substances of samples.The high quality DNA was extracted from fresh leaves,and could be used for SCoT-PCR marker analysis.
