A Rapid And Efficient Method For Enriching Mitochondrial Dna From Plants, Mackenzie M. Strehle, Emma Purfeerst, Alan C. Christensen

School of Biological Sciences: Faculty Publications

Current mitochondrial purification techniques are tedious and protracted due to their emphasis on recovering physiologically active mitochondria. However, for studies that are exclusively interested in isolating mitochondrial DNA (mtDNA) for applications such as PCR and sequencing, respiring mitochondria - and the complex procedures that stem from the need to retain their function - are unnecessary. Still, global DNA extraction methods have proven insufficient for mitochondrial DNA isolation because nuclear mitochondrial DNA segments (NUMTs) pose unique challenges to accurate mtDNA quantification and characterization. We present a rapid and simple extraction technique that maximizes recovery of mitochondrial DNA from plant cells, while …
