Which disease is caused by phytoplasma?
Species
| Species name | Associated disease |
|---|---|
| Ca. P. australasiaticum corrig. White et al. 1998 (Ca. P. australasia White et al. 1998) | Papaya mosaic |
| Ca. P. australiense Davis et al. 1997 | Australian grapevine yellows |

How do you treat phytoplasma?
Methods and results: In vitro grown periwinkle shoots infected with different ‘Candidatus Phytoplasma’ species were treated with indole-3-acetic acid (IAA) or indole-3-butyric acid (IBA). Both auxins induced recovery of phytoplasma-infected periwinkle shoots, but IBA was more effective.
What is the difference between bacteria and phytoplasma?
Phytoplasmas are single-celled organisms descended from bacteria, but they have lost the cell wall. They are considered mollicutes (“soft skin”), and able to change shape in response to their environment. Phytoplasmas are obligate parasites that only live in the phloem cells of plants or in their insect vectors.
Is phytoplasma a fungus?
Phytoplasmas are economically important plant pathogens that affect annual and perennial crops, bushes and fruit trees, ornamental trees, and natural floras worldwide. All phytoplasmas are transmitted by phloem-feeding insects, mostly leafhoppers, planthoppers, and psyllids.
What is the meaning of phytoplasma?
Definition of phytoplasma : any of a group of bacteria that are related to mycoplasmas, cause plant diseases (such as aster yellows or elm yellows) by infecting phloem tissue, and are transmitted especially by homopteran insect vectors.
What is the importance of phytoplasma?
Phytoplasmas are pathogenic bacterial Mollicutes inhabiting the plant phloem. They are associated with severe plant diseases in many different species worldwide, with huge economic impacts on several important crops (Maejima et al.
Is phytoplasma and mycoplasma same?
The main difference between mycoplasma and phytoplasma is that the mycoplasma refers to pleuropneumonia-like organisms (PPLOs), which can be parasitic in humans, animals, and plants whereas the phytoplasma refers to mycoplasma-like organisms (MLOs), which can be parasitic in plant phloem tissue and some insects.
What is meant by phytoplasma?
Who discovered phytoplasma as causal agent of plant disease?
Phytoplasmas, a large group of plant-pathogenic, phloem-inhabiting bacteria were discovered by Japanese scientists in 1967. They are transmitted from plant to plant by phloem-feeding insect hosts and cause a variety of symptoms and considerable damage in more than 1,000 plant species.
