  1. 1Fragment is PA0654 that precedes PA0655 and has 87% similarity over the common area.
  2. 2Includes SLY507, which seems to be a protein that spans regions of a number of methylases.
  3. List of putative methylases reported in ‘Candidatus Phytoplasma asteris’ (OY-M and AY-WB), ‘Ca. Phytoplasma australiense’ (PAa and SLY), and ‘Ca. Phytoplasma mali’ (AT) excluding those common to all five genomes. Possible additional genes or gene fragments are given in brackets.
