Candidatus ca. phytoplasma
WebThe phytoplasma life cycle involves replication in insects and plants. They infect the insect but are phloem-limited in plants. Members of Ca. Phytoplasma asteris (16SrI group phytoplasmas) are found in 80 monocot and dicot plant species in most parts of the world. Experimentally, they can be transmitted by approximately 30, frequently ... 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). Phytoplasma taxonomy is complicated because the organisms cannot be cultured; …
