‘Candidatus Phytoplasma pruni’, a novel taxon associated with X-disease of stone fruits, Prunus spp.: multilocus characterization based on 16S rRNA, secY, and ribosomal protein genes

Citation

Names
Ca. Phytoplasma pruni
Abstract
X-disease is one of the most serious diseases known in peach (Prunus persica). Based on RFLP analysis of 16S rRNA gene sequences, peach X-disease phytoplasma strains from eastern and western United States and eastern Canada were classified in 16S rRNA gene RFLP group 16SrIII, subgroup A. Phylogenetic analyses of 16S rRNA gene sequences revealed that the X-disease phytoplasma strains formed a distinct subclade within the phytoplasma clade, supporting the hypothesis that they represented a lineage

Isolation of an aerobic sulfur oxidizer from the SUP05/Arctic96BD-19 clade

Pseudothioglobus singularis Ts Pseudothioglobus Ca. Thioglobus singularis
Abstract
Abstract Bacteria from the uncultured SUP05/Arctic96BD-19 clade of gamma proteobacterial sulfur oxidizers (GSOs) have the genetic potential to oxidize reduced sulfur and fix carbon in the tissues of clams and mussels, in oxygen minimum zones and throughout the deep ocean (>200 m). Here, we report isolation of the first cultured representative from this GSO clade. Closely related cultures were obtained from surface waters in Puget Sound and from the deep chlorophyll maximum

‘Candidatus Phytoplasma balanitae’ associated with witches’ broom disease of Balanites triflora

Citation
Win et al. (2013). International Journal of Systematic and Evolutionary Microbiology 63 (Pt_2)
Names
Ca. Phytoplasma balanitae
Abstract
A phytoplasma was identified in naturally infected wild Balanites triflora plants exhibiting typical witches’ broom symptoms (Balanites witches’ broom: BltWB) in Myanmar. The 16S rRNA gene sequence revealed that BltWB phytoplasma had the highest similarity to that of ‘Candidatus Phytoplasma ziziphi’ and it was also closely related to that of ‘Candidatus Phytoplasma ulmi ’. Phylogenetic analysis of the 16S rRNA gene sequences indicated th

‘Candidatus Phytoplasma malaysianum’, a novel taxon associated with virescence and phyllody of Madagascar periwinkle (Catharanthus roseus)

Citation
Nejat et al. (2013). International Journal of Systematic and Evolutionary Microbiology 63 (Pt_2)
Names
Ca. Phytoplasma malaysianum
Abstract
This study addressed the taxonomic position and group classification of a phytoplasma responsible for virescence and phyllody symptoms in naturally diseased Madagascar periwinkle plants in western Malaysia. Unique regions in the 16S rRNA gene from the Malaysian periwinkle virescence (MaPV) phytoplasma distinguished the phytoplasma from all previously described ‘ Candidatus

‘Candidatus Phytoplasma convolvuli’, a new phytoplasma taxon associated with bindweed yellows in four European countries

Citation
Martini et al. (2012). International Journal of Systematic and Evolutionary Microbiology 62 (Pt_12)
Names
Ca. Phytoplasma convolvuli
Abstract
Plants of Convolvulus arvensis exhibiting symptoms of undersized leaves, shoot proliferation and yellowing, collectively defined as bindweed yellows, were sampled in different regions of Europe and assessed for phytoplasma infection by PCR amplification using phytoplasma universal rRNA operon primer pairs. Positive results were obtained for all diseased plants. RFLP analysis of amplicons comprising the16S rRNA gene alone or the16S rRNA gene and 16-23S intergenic spacer region indicated that the
