A method is presented for the rapid isolation of high-molecular-weight DNA from mature leaves of date palm (Phoenix dactylifera L.), using a CTAB-based buffer. The method yields up to 800 μg of DNA from 1 g of leaf tissues. The procedure was also suitable for DNA extraction from callus or buds from tissue culture. The DNA obtained through this method was a good substrate for at least seventeen restriction endonucleases. This method was also used to extract DNA from mature leaves of coconut and may be applicable to other species of palms.
