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

Graft Transmission and Cultivar Reaction of Citrus to ‘Candidatus Liberibacter americanus’

Citation
Lopes, Frare (2008). Plant Disease 92 (1)
Names
Ca. Liberibacter americanus
Abstract
Little is known about ‘Candidatus Liberibacter americanus’, a causal agent of huanglongbing or greening disease in Brazil, or its interaction with citrus trees. Greenhouse experiments were conducted with the objective of determining conditions favorable for transmission from field affected trees to young potted plants, to evaluate the reaction of multiple citrus species to the disease, and to determine the efficiency of pathogen propagation from individual buds. Single buds or bark pieces of va

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
