In 1992, the Subcommittee on the Taxonomy of Mollicutes proposed the use of 'Phytoplasma' rather than 'mycoplasma-like organisms' 'for reference to the phytopathogenic mollicutes'. In 2004, the generic name Phytoplasma was adopted and is currently of Candidatus (Ca.) status (used for bacteria that cannot be cultured). Phytoplasma taxonomy is complicated because the organisms cannot be cultured; …
