The protocol includes: organelle isolation, deoxyribonuclease treatment, lysis, deproteinisation and a final DNA purification with sodium dodecyl sulphate and potassium
acetate. The organelle DNA yield is 5–10 micrograms per gram of tissue and the DNA is fully restrictable. The technique is inexpensive and appropriate for the isolation of multiple
samples of organelle DNA from a small amount of tissue. - [Read A Method for Isolation of Chloroplast DNA and Mitochondrial DNA from Sunflower]
One step extraction for isolation of plant DNA. DNA suitable for amplification by PCR can be produced from leaf material smaller than 0.3 mm2 in less than 20 min & no tube changes. Method was tested on several plant species. Method was found to extract DNA that could be amplified without any further purification or treatment. The isolated DNA was amplified using a universal chloroplast primer set. The method was validated by comparing size of PCR products generated using standard DNA isolation. - [Read One-Step Isolation of Plant DNA Suitable for PCR Amplification]
