Abstract: | Isolating nucleic acids from sources rich in contaminants is particularly cumbersome when treating a large number of samples. Several protocols have been published that address the problem of nucleic acid extraction and purification, but few address sample number. We describe a method for extracting DNA from recalcitrant tree species by using a commercial grinding apparatus. This alleviates the hard work of sample preparation prior to lysis and purification. Our method has been tested extensively on different fruit tree species and in projects that require the simultaneous processing of hundreds of samples. Moreover, it does not require the availability of robotic workstations. |
