Comparison of the 'Ca. Liberibacter asiaticus' genome adapted for an intracellular lifestyle with other members of the Rhizobiales. [PDF]

PLoS ONE, 2011
An intracellular plant pathogen 'Candidatus Liberibacter asiaticus,' a member of the Rhizobiales, is related to Sinorhizobium meliloti, Bradyrhizobium japonicum, nitrogen fixing endosymbionts, Agrobacterium tumefaciens, a plant pathogen, and Bartonella ...

Graft Transmission Efficiencies and Multiplication of ‘Candidatus Liberibacter americanus’ and ‘Ca. Liberibacter asiaticus’ in Citrus Plants [PDF]

Phytopathology®, 2009
In Brazil ‘Candidatus Liberibacter asiaticus’ and ‘Ca. L. americanus’ cause huanglongbing (also known as greening), the most destructive citrus disease. A shift in pathogen prevalence was observed over time, with a disproportional increase in ‘Ca. L. asiaticus’ occurrence.

Rapid visual Candidatus Liberibacter asiaticus detection (citrus greening disease) using simple alkaline heat DNA lysis followed by loop-mediated isothermal amplification coupled hydroxynaphthol blue (AL-LAMP-HNB) for potential local use.

PLoS ONE, 2022
An outbreak of citrus greening or Huanglongbing disease bacteria occurs in many areas. We sampled and identified an ongoing ~year 2020 orange tree endemic in northern Thailand as Candidatus Liberibacter asiaticus.

A new and accurate qPCR protocol to detect plant pathogenic bacteria of the genus ‘Candidatus Liberibacter’ in plants and insects

Scientific Reports, 2023
Four pathogenic bacterial species of the genus ‘Candidatus Liberibacter’, transmitted by psyllid vectors, have been associated with serious diseases affecting economically important crops of Rutaceae, Apiaceae and Solanaceae families.

Growth parameters of Liberibacter crescens suggest ammonium and phosphate as essential molecules in the Liberibacter-plant host interface [PDF]

BMC Microbiology, 2019
Abstract Background Liberibacter crescens is the closest cultured relative of four important uncultured crop pathogens. Candidatus. L. asiaticus, L. americanus, L. africanus cause citrus greening disease, while Ca. L. solanacearum causes potato Zebra chip disease.

Prevalent Transmission of ‘Candidatus Liberibacter asiaticus’ over ‘Ca. Liberibacter americanus’ in a Long-Term Controlled Environment

Phytopathology®, 2022
In Brazil, citrus huanglongbing (HLB) is associated with ‘Candidatus Liberibacter americanus’ (CLam) and ‘Ca. Liberibacter asiaticus’ (CLas). However, there are few studies about HLB epidemiology when both Liberibacter spp. and its insect vector, the Asian citrus psyllid (ACP, Diaphorina citri), are present.

Liberibacter crescens gen. nov., sp. nov., the first cultured member of the genus Liberibacter

International Journal of Systematic and Evolutionary Microbiology, 2014
The Gram-stain-negative, rod-shaped bacterial isolate BT-1T is the closest relative to the genus ‘Candidatus Liberibacter ’ cultured to date. BT-1T was recovered from the phloem sap of a defoliating mountain papaya in Puerto Rico.

RNAi-Mediated Attenuation of CsCalS7-Related Transcripts Mitigates Callose Accumulation and Huanglongbing Symptoms. [PDF]

Mol Plant Pathol
Partial CsCalS7 suppression reduces phloem callose, starch accumulation and huanglongbing symptoms, supporting a threshold‐based host tolerance. ABSTRACT Huanglongbing (HLB) is the most destructive citrus disease worldwide and is characterised by excessive callose deposition at sieve plates, which has been associated with impaired carbohydrate ...

Cryptic haplotypes of “ Candidatus Liberibacter africanus” [PDF]

, 2015
Abstract “ Candidatus Liberibacter africanus” (Laf) has long been recognised as a causal agent of the devastating citrus disease huanglongbing (HLB) or citrus greening. This species is currently restricted to Africa, the Arabian Peninsula and some Indian Ocean islands and vectored ...

Functional and Comparative Genomic Analysis of Integrated Prophage-Like Sequences in “Candidatus Liberibacter asiaticus”

mSphere, 2019
Huanglongbing disease (HLB; yellow shoot disease) is a severe worldwide infectious disease for citrus family plants. The pathogen “Candidatus Liberibacter asiaticus” is an alphaproteobacterium of the Rhizobiaceae family that has been identified as the ...
