P. Nath et al., A SIMPLE METHOD FOR THE PURIFICATION OF ORGANELLE DNA OF PLANTS, Journal of Plant Biochemistry and Biotechnology, 2(2), 1993, pp. 117-120
We report here a simple procedure for the purification of the organell
e DNA. Mitochondrial DNA from Sorghum and the chloroplast DNA from Pop
ulus and spinach were purified using this protocol. The method utilize
s a quick centrifugation of the isolated organelle DNA through a two s
tep CsCl density gradient for removal of small molecular weight nuclei
c acids which pose a major problem for getting clean restriction patte
rns. This method of purification can be adopted with any isolation pro
cedure for organelle DNA.
