WebPresently, all four phytoplasmas are A-rated pathogens in California. However, research has shown that these phytoplasmas are actually strains of Candidatus Phytoplasma pruni. Therefore, the status of the four phytoplasmas and their current rating in California are reviewed herein and a new permanent rating is proposed. History & Status: WebPhylogenetic comparisons between the 16S rRNA genes of StLL phytoplasma and other 'Candidatus Phytoplasma' species indicate that StLL represents a distinct phytoplasma lineage. It shares its most recent known ancestry with 'Ca. Phytoplasma luffae' (16SrVIII-A), with which it has 97.17-97.25 % nucleotide identity. Phytoplasmas belong to the monotypic order Acholeplasmatales. 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).
