Abstract
We describe an inexpensive method for dehydration of plant tissue and extraction of high molecular weight DNA. Tissue is dried for 12 to 24 hours in a food dehydrator and subsequently powdered for DNA extraction. Dicot tissue can be powdered in centrifuge tubesen masse using a commercial paint mixer and glass beads. With the use of the paint mixer, tissue never touches common surfaces that might lead to cross contamination, a potential benefit when the DNA is to be used for PCR reactions. The DNA is of a quality equal to that obtained from either lyophilized or fresh frozen tissue (commonly used in many labs). The advantages of the described procedure are that it is fast, does not require expensive equipment (e.g., lyophilizer) and can be used in situations where large numbers of samples must be extracted.
