 Extracting high quality genome DNA from plant is a vital step in plant molecular biology research. But it is relatively difficult to obtain high quality DNA from plant species which are rich in polysaccharides, polyphenols, and other secondary metabolites. This method was developed bases on common CTAB and commercial kit method with some modifications and features removing interfering material prior to the cell lysis. High quality DNA was obtained by this method from a variety of plant species and evaluated by electrophoresis and spectrometer methods. We demonstrated that it is a common plant genomic DNA extraction method especially suitable for some difficult plant species.

Key words: Plant genome DNA, Modified common DNA extraction method, Plant material
