Population Structures of ‘Candidatus Liberibacter asiaticus’ in Southern China

Citation
Ma et al. (2014). Phytopathology® 104 (2)
Names
Ca. Liberibacter asiaticus
Abstract
Huanglongbing (HLB) is a highly detrimental citrus disease associated with ‘Candidatus Liberibacter asiaticus’, a nonculturable alpha-proteobacterium. Characterization of the bacterial populations is important for development of disease management strategies. In this study, the ‘Ca. L. asiaticus’ populations in eight provinces in southern China where HLB is endemic were analyzed based on tandem repeat number (TRN) variations in a previously characterized genomic locus CLIBASIA_01645. Of the 224

A Phytoplasma Related to ‘Candidatus Phytoplasma asteris’ Detected in Citrus Showing Huanglongbing (Yellow Shoot Disease) Symptoms in Guangdong, P. R. China

Citation
Chen et al. (2009). Phytopathology® 99 (3)
Names
Ca. Phytoplasma asteris
Abstract
Citrus huanglongbing (HLB) or yellow shoot disease (i.e., greening disease) is highly destructive to citrus production worldwide. Understanding the etiology of HLB is critical for managing the disease. HLB is currently associated with infection by ‘Candidatus Liberibacter spp.’ around the world, including China. However, Koch's postulates have not been fulfilled. In addition, other plant pathogens also may be involved in HLB. In a survey performed in Guangdong Province, P. R. China in 2006 and

First Report of ‘Candidatus Liberibacter asiaticus’ from Atalantia buxifolia in Guangdong, China

Citation
Deng et al. (2008). Plant Disease 92 (2)
Names
Ca. Liberibacter asiaticus
Abstract
Atalantia buxifolia (Poir.) Oliv., synonym Severinia buxifolia (Poir.) Ten. as commonly found in literature, is a common landscape plant and a popular Chinese medicinal herb known as Jiubingle or Dongfengjie. It remains unclear if this rutaceous plant could host ‘Candidatus Liberibacter asiaticus’, the pathogen of citrus Huanglongbing (HLB) in Guangdong, P. R. China. This information is important for HLB control in citrus because infected A. buxifolia could serve as a source of inoculum. In Aug

Nested-PCR Detection and Sequence Confirmation of ‘Candidatus Liberibacter asiaticus’ from Murraya paniculata in Guangdong, China

Citation
Deng et al. (2007). Plant Disease 91 (8)
Names
Ca. Liberibacter asiaticus
Abstract
Murraya paniculata (orange jasmine) is a popular ornamental rutaceaous plant and is known to be a preferred host for the Asian citrus psyllid, Diaphorina citri (Kuwayana), the primary vector of ‘Candidatus Liberibacter spp.’ that causes citrus Huanglongbing (HLB). HLB is a highly destructive citrus disease worldwide. However, the presence of ‘Ca. Liberibacter spp.’ in M. paniculata remains uncertain (2). Clarification of M. paniculata as a host of ‘Ca. Liberibacter spp.’ has direct impact on HL
