Continuous distribution of Mycoplasma genome sizes.
Genome sizes of eleven strains of eight species of Mollicutes Mycoplasmataceae were investigated by pulsed-field gel electrophoresis. Mycoplasma genomic sizes were determined from the sum of the sizes of fragments obtained after digestion of genomic DNA with restriction endonucleases. The sizes of the fragments were determined by comparison of their electrophoretic mobilities with those of lambda DNA concatemers. Specific restriction endonucleases were chosen so that after digestion three to ten fragments were obtained. The values for genome size derived by this method showed a continuous distribution that ranged from approximately 650 kb for Mycoplasma hyorhinis BTS-7 to 1600 kb for Acholeplasma laidlawii FHM.
