'Candidatus Phytoplasma brasiliense', a new phytoplasma taxon associated with hibiscus witches' broom disease.
Hibiscus rosa-sinensis is a valuable ornamental species widely planted in Brazil. Many plants are affected by witches' broom disease, which is characterized by excessive axillary branching, abnormally small leaves, and deformed flowers, symptoms that are characteristic of diseases attributed to phytoplasmas. A phytoplasma was detected in diseased Hibiscus by amplification of rRNA operon sequenc...
متن کامل"Candidatus phytoplasma australiense," a new phytoplasma taxon associated with Australian grapevine yellows.
A phytoplasma was detected in naturally diseased 'Chardonnay' grapevines exhibiting symptoms of Australian grapevine yellows disease. The use of PCR designed to amplify phytoplasma DNA resulted in detection of phytoplasma DNA in all of the diseased plants examined; no phytoplasma DNA was detected in healthy seedling grapevines. The collective restriction fragment length polymorphism (RFLP) patt...
متن کاملDraft genome sequence of the New Jersey aster yellows strain of ‘Candidatus Phytoplasma asteris’
The NJAY (New Jersey aster yellows) strain of 'Candidatus Phytoplasma asteris' is a significant plant pathogen responsible for causing severe lettuce yellows in the U.S. state of New Jersey. A draft genome sequence was prepared for this organism. A total of 177,847 reads were assembled into 75 contigs > 518 bp with a total base value of 652,092 and an overall [G+C] content of 27.1%. A total of ...
متن کاملThe phytoplasma associated with ash yellows and lilac witches'-broom: 'Candidatus phytoplasma fraxini'.
Phytoplasmas associated with the plant diseases ash yellows (AshY, occurring in Fraxinus) and lilac witches'-broom (LWB, occurring in Syringa) represent a putative species-level taxon. Phytoplasmal DNA from 19 ash or lilac sources across the known geographic range of AshY (71-113 degrees W) was examined to determine if AshY and LWB phytoplasmas are a coherent group, if variability exists in bot...
متن کاملIdentification of Graminella nigrifrons as a potential vector for phytoplasmas affecting Prunus and Pyrus species in Canada
Prunus and Pyrus species affected with phytoplasma diseases, as well as leafhopper species collected from Prunus and Pyrus fields in Ontario, Canada were tested for presence of phytoplasmas. Preliminary results showed that Graminella nigrifrons is a potential vector for phytoplasma groups 16SrI-W (‘Candidatus Phytoplasma asteris’), and 16SrVII-A (‘Candidatus Phytoplasma fraxini’) to a variety o...
