Liberibacter crescens biofilm formation in vitro: establishment of a model system for pathogenic ‘Candidatus Liberibacter spp.’ [PDF]

Scientific Reports, 2019
AbstractThe Liberibacter genus comprises insect endosymbiont bacterial species that cause destructive plant diseases, including Huanglongbing in citrus and zebra chip in potato. To date, pathogenic ‘Candidatus Liberibacter spp.’ (CLs) remain uncultured, therefore the plant-associated Liberibacter crescens (Lcr), only cultured species of the genus, has ...

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 ...

Comparative Phylogenomic Analysis Reveals Evolutionary Genomic Changes and Novel Toxin Families in Endophytic Liberibacter Pathogens

Microbiology Spectrum, 2021
Liberibacter pathogens are the causative agents of several severe crop diseases worldwide, including citrus Huanglongbing and potato zebra chip. These bacteria are endophytic and nonculturable, which makes experimental approaches challenging and ...

Liberibacters associated with orange jasmine in Brazil: incidence in urban areas and relatedness to citrus liberibacters [PDF]

Plant Pathology, 2010
Two surveys (2005/2006 and 2009) were conducted in the state of São Paulo, Brazil, to investigate the incidence of ‘ Candidatus Liberibacter asiaticus’ and ‘ Ca.  L.

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.

'Candidatus Liberibacter asiaticus' Effector SDE525 hijacks NACα to Suppress Jasmonic Acid-Mediated Immunity in Citrus. [PDF]

Mol Plant Pathol
The ‘Candidatus Liberibacter asiaticus’ secreted protein SDE525 suppresses the plant jasmonic acid defence pathway by targeting the citrus NACα protein, thereby weakening citrus resistance against the Asian citrus psyllid. ABSTRACT Citrus huanglongbing (HLB), caused by the phloem‐limited bacterium ‘Candidatus Liberibacter asiaticus’ (CLas), is one of ...

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.

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.
