Transcriptomic 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 کاملIdentification and characterization of conserved and variable regions of lime witches' broom phytoplasma genome.
Several segments (∼20 kbp) of the lime witches' broom (LWB) phytoplasma genome (16SrII group) were sequenced and analysed. A 5.7 kbp segment (LWB-C) included conserved genes whose phylogenetic tree was consistent with that generated using 16S rRNA genes. Another 6.4 kbp LWB phytoplasma genome segment (LWB-NC) was structurally similar to the putative mobile unit or sequence variable mosaic ge...
متن کامل'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 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 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...
