A new protocol for isolation of mitochondrial DNA from cotton seedlings.
A procedure to isolate mtDNA from cotton seedlings G. hirsutum and G. barbadense has been developed. The new protocol allows for the isolation of cotton mtDNA of high purity, yield and digestibility by restriction endonucleases. The success of the protocol is based on critical adjustments in the ionic strength of the homogenizing medium and washing buffer, the speed of grinding during homogenization, and the methods used for lysis of the mitochondria.
