Study on extraction methods of bryophytes genomic DNA

The extraction of high quality DNA was the basis of the study for genetic diversity of Bryophytes. The results of 5 kinds of method for extracting DNA were compared using Bryophytes species as materials. The results showed that the fast extraction method which was designed by our research group and improved CTAB method were 2 kinds of method suitable to the high quality DNA for Bryophytes. The purity of extracted DNA by the two methods was high and their fragment was clearly shown by agarose gel electrophoresis. DNA extracted by the two methods was ready to be used as templates for PCR amplification.
