| Abstract: | Objective] The research aimed to optimize the extraction methods for genomic DNA on Eomecon chionantha Hance.Method] The methods of CTAB and modified CTAB were chose to extract the genomic DNA on Eomecon chionantha Hance leaves.Result] The results showed that the genomic DNA extracted by CTAB method contained many impurity,were difficult to dissolve and easily degradable.The modified CTAB method was suitable to extract the genomic DNA on Eomecon chionantha Hance.The concentration and extraction rate of DNA from both fresh leaves and dry leaves preserved with silica gel at -80 ℃ were higher.Conclusion] The study can provide the basis for studying the genetic diversity of Eomecon chionantha Hance. |
