'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 castaneae', a novel phytoplasma taxon associated with chestnut witches' broom disease.
In Korea, Japanese chestnut trees (Castanea crenata Sieb. and Zucc.) showing symptoms indicative of witches' broom disease, including abnormally small leaves and yellowing of young leaves, were examined. Since the symptoms were suggestive of a phytoplasma infection, tissues were assayed for phytoplasmas by PCR analysis using a pair of universal primers that amplify a 1.4-kbp phytoplasma 16S rDN...
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 کاملTranscriptomic Analysis of Paulownia Infected by Paulownia Witches'-Broom Phytoplasma
Phytoplasmas are plant pathogenic bacteria that have no cell wall and are responsible for major crop losses throughout the world. Phytoplasma-infected plants show a variety of symptoms and the mechanisms they use to physiologically alter the host plants are of considerable interest, but poorly understood. In this study we undertook a detailed analysis of Paulownia infected by Paulownia witches'...
متن کاملAn antigenic protein gene of a phytoplasma associated with sweet potato witches' broom.
A gene encoding the major antigenic protein of phytoplasma associated with sweet potato witches' broom (SPWB) was cloned and analysed by screening the genomic library of SPWB phytoplasma with monoclonal antibodies for SPWB phytoplasma. The entire predicted structural gene encoded an antigenic protein composed of 172 amino acids with a computed molecular mass of 19.15 kDa and a pl value of 9.78....
