Identification of the genes required for the culture of Liberibacter crescens, the closest cultured relative of the uncultured Liberibacter plant pathogens [PDF]

Frontiers in Microbiology, 2016
Here Tn5 random transposon mutagenesis was used to identify the essential elements for culturing Liberibacter crescens BT-1 that can serve as antimicrobial targets for the closely related pathogens of citrus, Candidatus Liberibacter asiaticus (Las) and ...

Laboratory Protocols for Candidatus Liberibacter asiaticus Transmission Biology and Management Research. [PDF]

Curr Protoc
Abstract Candidatus Liberibacter asiaticus (CLas), the causal agent of Huanglongbing, is transmitted by the Asian citrus psyllid (Diaphorina citri) in a persistent, propagative manner. Reproducible transmission studies require not only controlled inoculation assays but also standardized propagation of citrus host plants, maintenance of D.

Genome-wide analyses of Liberibacter species provides insights into evolution, phylogenetic relationships, and virulence factors. [PDF]

Molecular Plant Pathology, 2020
'Candidatus Liberibacter' species are insect-transmitted, phloem-limited α-Proteobacteria in the order of Rhizobiales. The citrus industry is facing significant challenges due to huanglongbing, associated with infection from 'Candidatus Liberibacter ...

Characterization of copy numbers of 16S rDNA and 16S rRNA of Candidatus Liberibacter asiaticus and the implication in detection in planta using quantitative PCR [PDF]

BMC Research Notes, 2009
Background Citrus Huanglongbing (HLB) is one of the most devastating diseases on citrus and is associated with Candidatus Liberibacter spp.. The pathogens are phloem limited and have not been cultured in vitro.

Genetic Signatures of Contrasted Outbreak Histories of “Candidatus Liberibacter asiaticus”, the Bacterium That Causes Citrus Huanglongbing, in Three Outermost Regions of the European Union [PDF]

Evolutionary Applications
In an era of trade globalization and climate change, crop pathogens and pests are a genuine threat to food security. The detailed characterization of emerging pathogen populations is a prerequisite for managing invasive species pathways and designing ...

Pathogenicity and Transcriptomic Analyses of Two “Candidatus Liberibacter asiaticus” Strains Harboring Different Types of Phages

Microbiology Spectrum, 2023
“Candidatus Liberibacter asiaticus” is one of the putative causal agents of citrus Huanglongbing (HLB), a highly destructive disease threatening the global citrus industry. Several types of phages had been identified in “Ca.

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.
