摘要
In the study, we present a fast, simple and inexpensive protocol for isolating chloroplast and mitochondrial DNA from one rapeseed leaf tissue sample. The chloroplast and mitochondria were separated from the same green leaf tissue by differential centrifugations. The protocol is the first report that isolates plant chloroplast DNA (cpDNA) and mitochondrial DNA (mtDNA) from the same sample homogenate. The organelle DNA yield is 2-10 micrograms per gram of tissue; the DNA was fully restrictable and was successfully used for sequencing.
