‘Candidatus Phytoplasma costaricanum’ a novel phytoplasma associated with an emerging disease in soybean (Glycine max)

Citation
Lee et al. (2011). International Journal of Systematic and Evolutionary Microbiology 61 (12)
Names
Ca. Phytoplasma costaricanum
Abstract
A novel phytoplasma, designated strain SoyST1c1, associated with a newly emerging disease in soybean (Glycine max), known as soybean stunt (SoyST), was found in 2002 in a soybean plantation in Alajuela Province, Costa Rica. The same phytoplasma, or a very closely related strain, also infected sweet pepper (Capsicum annuum) with purple vein syndrome (SwPPV) and passion fruit vine (Passiflora edulis) with bud proliferation disease (PasFBP) in the same region. Sequence analysis of cloned 16S rRNA g

First Report of ‘Candidatus Phytoplasma asteris’ Associated with Oilseed Rape Phyllody in Poland

Citation
Zwolińska et al. (2011). Plant Disease 95 (11)
Names
Ca. Phytoplasma asteris
Abstract
Winter oilseed rape (Brassica napus L.) is widely grown in Poland to produce vegetable oil for industrial processing of human and animal feed. In recent years, according to European Union directives on the use of biofuels (Directive 2003/30/EC), the area under oilseed rape cultivation in Poland has dramatically increased to 810,000 ha in 2009 and is still increasing. Morphological deformations of winter oilseed rape indicative of phytoplasma infection have been observed sporadically in Poland s

Incidence and Severity of Huanglongbing and Candidatus Liberibacter asiaticus Titer among Field-infected Citrus Cultivars

Citation

Names
Ca. Liberibacter asiaticus
Abstract
Incidence and severity of Huanglongbing (HLB) disease were assessed in Apr. 2010 among eight citrus cultivars representing diverse scion types growing in commercial groves in Florida's Indian River region, an area with a high incidence of HLB. In each grove, 20 trees of each cultivar were rated for visual HLB symptoms and leaves were collected for quantitative polymerase chain reaction quantification of Candidatus Liberibacter asiaticus (CLas), the presumptive causal agent of HLB. There was a st
