Identification of candidate structured RNAs in the marine organism 'Candidatus Pelagibacter ubique'

Citation
Meyer et al. (2009). BMC Genomics 10 (1)
Names
Ca. Pelagibacter ubique
Abstract
Abstract Background Metagenomic sequence data are proving to be a vast resource for the discovery of biological components. Yet analysis of this data to identify functional RNAs lags behind efforts to characterize protein diversity. The genome of 'Candidatus Pelagibacter ubique' HTCC 1062 is the closest match for approximately 20% of marine metagenomic sequence reads. It is also small, contains little non-coding DNA, and has strikingly low GC content.

First Report of Aster Yellow Phytoplasmas (‘Candidatus Phytoplasma asteris’) in Canadian Grapevines

Citation
Olivier et al. (2009). Plant Disease 93 (6)
Names
Ca. Phytoplasma asteris
Abstract
In North America, elm yellows, aster yellows (AY), and X-disease phytoplasmas have been detected in American grapevines (1), and recently, Bois noir was detected in Canadian vineyards from British Columbia (BC) and Ontario (ON) (2). Typical symptoms of grapevine yellows (GY) include leaf rolling and chlorosis, uneven or total lack of lignification of canes, flower abortion or berry withering, and stunting. In 2006 and 2007, independent surveys were conducted by the Canadian Food Inspection Agen

First Report of ‘Candidatus Liberibacter asiaticus’ Associated with Citrus Huanglongbing in the Dominican Republic

Citation
Matos et al. (2009). Plant Disease 93 (6)
Names
Ca. Liberibacter asiaticus
Abstract
In August 2008, unusual symptoms were observed in Mexican lime trees (Citrus aurantifolia (Christm.) Swing) in the municipality of Luperón, province of Puerto Plata on the north coast of the Dominican Republic. Symptoms observed in young and old trees included blotchy mottle on leaves, healthy-appearing larger branches with smaller side branches that displayed chlorotic leaves, abscised and lopsided fruit, and branch dieback, all symptoms similar to those of citrus huanglongbing associated with

Promoter Characterization in the AT-Rich Genome of the Obligate Endosymbiont “ Candidatus Blochmannia floridanus”

Citation
Stoll et al. (2009). Journal of Bacteriology 191 (11)
Names
Ca. Blochmannia floridanus
Abstract
ABSTRACT The characterization of transcriptional start sites of 14 genes encoded by the extremely AT-rich genome of “ Candidatus Blochmannia floridanus” revealed a high degree of conservation with the RpoD promoter consensus sequence of the free-living relative Escherichia coli . Moreover, in agreement with the presence of the alternative heat shock sigma factor RpoH in “ Ca . Blochmannia,” typical Rpo

Association of ‘Candidatus Liberibacter solanacearum’ with Zebra Chip Disease of Potato Established by Graft and Psyllid Transmission, Electron Microscopy, and PCR

Citation
Secor et al. (2009). Plant Disease 93 (6)
Names
“Liberibacter solanacearum”
Abstract
A new disease of potatoes, tentatively named zebra chip (ZC) because of the intermittent dark and light symptom pattern in affected tubers which is enhanced by frying, was first found in Mexico in 1994 and in the southwestern United States in 2000. The disease can cause severe economic losses in all market classes of potatoes. The cause of ZC has been elusive, and only recently has been associated with ‘Candidatus Liberibacter’ sp. Field samples of potato plants were collected from several loca

Detection and Molecular Characterization of a ‘Candidatus Phytoplasma asteris’-Related Strain Infecting Sasa fortunei in China

Citation
Zhang et al. (2009). Plant Disease 93 (5)
Names
Ca. Phytoplasma asteris
Abstract
Bamboos are ecologically and economically valuable plants. Young shoots of almost all species are edible, either raw or cooked, and are major components of Asian cuisine while culms are used for furniture or handicrafts as well as fuel wood. Symptoms indicative of phytoplasma disease were observed on Sasa fortunei (van Houtte) Fiori during a survey in Yangling, Shaanxi Province, China during 2007. Symptoms included internode shortening, a mosaic pattern on leaves of diminished size, stunted gro
