Diversity of “ Candidatus Liberibacter asiaticus,” Based on the omp Gene Sequence [PDF]

Applied and Environmental Microbiology, 2005
ABSTRACT Huanglongbing (yellow dragon disease) is a destructive disease of citrus. The etiological agent is a noncultured, phloem-restricted alpha-proteobacterium, “ Candidatus Liberibacter africanus” in Africa and “ Candidatus Liberibacter asiaticus” in Asia. In this study, we used

Rootstock impacts on citrus flush dynamics, vegetative growth, and Diaphorina citri infestation and dispersion: Implications for huanglongbing management

Pest Management Science, EarlyView.
Dwarfing citrus rootstocks restrict flush shoot growth on the scion, thereby reducing Asian citrus psyllid infestation, dispersal, and huanglongbing (HLB) progression. These findings support the use of dwarfing rootstocks as an effective cultural strategy in integrated HLB management for citrus orchards.

Confirmation of the Sequence of ‘Candidatus Liberibacter asiaticus’ and Assessment of Microbial Diversity in Huanglongbing-Infected Citrus Phloem Using a Metagenomic Approach

Molecular Plant-Microbe Interactions, 2009
The citrus disease Huanglongbing (HLB) is highly destructive in many citrus-growing regions of the world. The putative causal agent of this disease, ‘Candidatus Liberibacter asiaticus’, is difficult to culture, and Koch's postulates have not yet been ...

Optimization of vqPCR for Reliable Detection of Viable Candidatus Liberibacter asiaticus in Citrus

HortScience, 2022
Citrus Huanglongbing (HLB, also known as “citrus greening”), an important disease worldwide, is associated with three species of phloem-limited Candidatus liberibacter, of which Candidatus L.

Relative Influence of Rootstock and Scion on Asian Citrus Psyllid Infestation and Candidatus Liberibacter asiaticus Colonization

Hortscience, 2023
The citrus industry in Florida faces a destructive endemic disease, known as huanglongbing (HLB), associated with Candidatus Liberibacter asiaticus (CLas), a phloem-limited bacterium, and transmitted by the Asian citrus psyllid (ACP).

Low Rates of Kaolin in Different Application Periods Reduce Diaphorina citri Population and Huanglongbing Incidence in Commercial Citrus Orchards

Journal of Applied Entomology, EarlyView.
ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide, and it has been disseminated by the Asian citrus psyllid Diaphorina citri, the vector of the causing agent Candidatus Liberibacter asiaticus. Although processed kaolin reduces psyllid infestation, long‐term field data from commercial orchards are limited.

A Systematic Map to Identify Knowledge Gaps on a Vector of Citrus Greening Diseases: The African Citrus Triozid, Trioza erytreae (Del Guercio, 1918) (Hemiptera: Triozidae)

Journal of Applied Entomology, EarlyView.
ABSTRACT Globally, citrus production areas are threatened by greening diseases, also known as Huánglóngbíng (HLB), associated with phloem‐limited gram‐negative species of the genus Candidatus Liberibacter. Those pathogens are transmitted by either the Asian citrus psyllid, Diaphorina citri Kuwayama 1908 (Hemiptera: Psyllidae), or the African citrus ...
