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 ...

Uncovering Symbionts Across the Psyllid Tree of Life and the Discovery of a New Liberibacter Species, “Candidatus” Liberibacter capsica [PDF]

Frontiers in Microbiology, 2021
Sap-feeding insects in the order Hemiptera associate with obligate endosymbionts that are required for survival and facultative endosymbionts that can potentially modify resistance to stress, enemies, development, and reproduction.

A synthetic ‘essentialome’ for axenic culturing of ‘Candidatus Liberibacter asiaticus’

BMC Research Notes, 2022
Objective ‘Candidatus Liberibacter asiaticus’ (CLas) is associated with the devastating citrus ‘greening’ disease. All attempts to achieve axenic growth and complete Koch’s postulates with CLas have failed to date, at best yielding complex cocultures ...

'Candidatus Liberibacter asiaticus' Effector SDE4250 Targets Citrus Proteasome Protein RPN10 to Inhibit Salicylic Acid-Mediated Citrus Immunity. [PDF]

Mol Plant Pathol
SDE4250 suppressed 26S proteasome activity by targeting CsRPN10 and enhancing its degradation via the proteasome pathway. This impairment of proteasome function subsequently attenuates SA‐mediated defence responses, thereby increasing citrus susceptibility to promote CLas infection.

Genome-Wide Association Study Reveals Insect Genetics and Microbial Symbiont Effects on Susceptibility of Diaphorina citri to the Citrus Greening Pathogen, Candidatus Liberibacter Asiaticus. [PDF]

Adv Sci (Weinh)
This study investigates the genetic and microbial factors influencing the susceptibility of Diaphorina citri to the citrus greening pathogen Candidatus Liberibacter asiaticus (CLas), employing a microbiome Genome Wide Association Study. The research identifies a key gene encoding an MFS‐type transporter contributing to CLas infectivity and abundance in

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.

Psyllid Cysteine Cathepsins Directly Cleave the Outer Membrane Protein BamD of Citrus Huanglongbing Pathogen. [PDF]

Plant Biotechnol J
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.

Distribution of Candidatus Liberibacter species in Eastern Africa, and the First Report of Candidatus Liberibacter asiaticus in Kenya [PDF]

Scientific Reports, 2020
AbstractHuanglongbing (HLB) is a serious disease of Citrus sp. worldwide. In Africa and the Mascarene Islands, a similar disease is known as African citrus greening (ACG) and is associated with the bacterium Candidatus Liberibacter africanus (Laf). In recent years, Candidatus Liberibacter asiaticus (Las) associated with the severe HLB has been reported

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.

Unravelling the Pathogenesis and Molecular Interactions of Liberibacter Phytopathogens with Their Psyllid Vectors

Agronomy, 2020
Insect-borne bacterial pathogens pose a global economic threat to many agricultural crops. Candidatus liberibacter species, vectored by psyllids (Hemiptera: psylloidea), are an example of devastating pathogens related to important known diseases such as ...
