Conserved core genes of PMUs. Gene order (5′-3′) of three and four highly conserved genes found in the Potential Mobile Units (PMUs) of ‘Ca. Phytoplasma australiense’ and ‘Ca. Phytoplasma asteris’. The “AY-WB PMU” arrangement is the only one found in AY-WB, the “SLY PMU” arrangement is the only type found in SLY, whereas OY-M and PAa have examples of both types.
