ABSTRACT
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.
