A Rapid and Efficient Method for the Isolation of Mitochondrial DNA From Wheat Crop

Muhammad Ejaz, Zhang Gaisheng, Zhu Qidi, Zhang Xinbo


The mitochondrial DNA was isolated from wheat (Triticum aestivum) crop in combination of different centrifugation and density gradient ultracentrifugation, DNaseI enzyme treatment, sucrose sedimentation; lysis with SDS and potassium proteinase. Pure mitochondrial DNA was successfully obtained by phenol/chloroform/isoamyl alcohol extraction to remove protein, and digested with RNase phenol/chloroform extraction method. To detect mitochondrial DNA purity, specific primers were designed for nuclear (Beta-actin) and mitochondrial (COXII) gene. Isolated mitochondrial DNA is pure, suitable for PCR and genetic analysis.
