The genome size of a plant-pathogenic mycoplasmalike organism resembles those of animal mycoplasmas.

The genome size of a mycoplasmalike organism was determined by comparing fluorescence intensities of restriction fragments. Its genome size was similar to that of Mycoplasma gallisepticum and much smaller than that of Acholeplasma laidlawii. Although the genome size is "mycoplasmalike," other molecular data indicate a closer evolutionary relationship to A. laidlawii.
