The Power of Electropenetrography in Enhancing Our Understanding of Host Plant-Vector Interactions

Insects, 2019
The invasive Asian citrus psyllid, Diaphorina citri (Hemiptera: Liviidae), is the primary vector of the phloem-infecting bacterium, Candidatus Liberibacter asiaticus. Candidatus L.

‘Ca. Liberibacter asiaticus’ Carries an Excision Plasmid Prophage and a Chromosomally Integrated Prophage That Becomes Lytic in Plant Infections

Molecular Plant-Microbe Interactions, 2011
Huanglongbing (HLB), also known as citrus greening, is a lethal disease of citrus caused by several species of ‘Candidatus Liberibacter’, a psyllid-transmitted, phloem-limited, alpha proteobacteria. ‘Ca.

First report of ‘Candidatus Liberibacter asiaticus’ in Diaphorina communis [PDF]

Australasian Plant Disease Notes, 2011
Huanglongbing (HLB) or citrus greening is one of the most destructive diseases of citrus in the world and one of the major factors limiting citrus production in south east Asia including Bhutan. The presence of ‘Candidatus Liberibacter asiaticus’, associated with the Asiatic form of HLB, was confirmed by conventional and real-time PCR in adults of the ...

Physiochemical changes mediated by “Candidatus Liberibacter asiaticus” in Asian citrus psyllids [PDF]

Scientific Reports, 2019
AbstractPlant pathogenic bacteria interact with their insect host(s)/vector(s) at the cellular and molecular levels. This interaction may alter the physiology of their insect vector, which may also promote the growth and transmission of the bacterium. Here we studied the effect of “Candidatus Liberibacter asiaticus” (“Ca. L.

Evaluation of Candidatus Liberibacter Asiaticus Efflux Pump Inhibition by Antimicrobial Peptides

Molecules, 2022
Citrus greening, also known as Huanglongbing (HLB), is caused by the unculturable bacterium Candidatus Liberibacter spp. (e.g., CLas), and has caused a devastating decline in citrus production in many areas of the world. As of yet, there are no definitive treatments for controlling the disease.

Psyllid Cysteine Cathepsins Directly Cleave the Outer Membrane Protein BamD of Citrus Huanglongbing Pathogen

Plant Biotechnology Journal, EarlyView.
ABSTRACT Candidatus Liberibacter asiaticus (CLas), the causative agent of citrus Huanglongbing (HLB), is transmitted by Asian citrus psyllid, Diaphorina citri; however, the role of the insect's immune effectors in defending against CLas remains poorly understood. This study reveals that D.

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 ...

Transcriptional Analyses of Mandarins Seriously Infected by ‘Candidatus Liberibacter asiaticus’

PLOS ONE, 2015
A range of leaf symptoms, including blotchy mottle, yellowing, and small, upright leaves with a variety of chlorotic patterns resembling those induced by zinc deficiencies, are associated with huanglongbing (HLB, yellow shoot disease), a worldwide destructive citrus disease.
