Selective Autophagy Receptor CsNBR1 Confers Citrus Huanglongbing Resistance by Degrading 'Candidatus Liberibacter Asiaticus' Virulence Effectors. [PDF]

Mol Plant Pathol
Overexpression of CsNBR1 confers HLB resistance in citrus by degrading CLas effector proteins, including SDE5115, SDE1, SDE19 and SDE5, via the autophagy pathway. ABSTRACT The selective autophagy receptor NEIGHBOUR OF BRCA1 (NBR1) is a key regulator of plant immunity, but its role against bacterial pathogens remains poorly understood.

The protein interactome of the citrus Huanglongbing pathogen Candidatus Liberibacter asiaticus. [PDF]

Nat Commun, 2023
AbstractThe bacterium Candidatus Liberibacter asiaticus (CLas) causes citrus Huanglongbing disease. Our understanding of the pathogenicity and biology of this microorganism remains limited because CLas has not yet been cultivated in artificial media.

A synthetic 'essentialome' for axenic culturing of 'Candidatus Liberibacter asiaticus'. [PDF]

BMC Res Notes, 2022
Abstract 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 with very low CLas titers detectable only by PCR.

'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 ...

'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

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

Transcriptome Profiling of ‘ Candidatus Liberibacter asiaticus’ in Citrus and Psyllids [PDF]

Phytopathology®, 2021
‘Candidatus Liberibacter asiaticus’ (Las) is an emergent bacterial pathogen that is associated with the devastating citrus huanglongbing (HLB). Vectored by the Asian citrus psyllid, Las colonizes the phloem tissue of citrus, causing severe damage to infected trees.

'Candidatus Liberibacter Asiaticus' Effector SECP8 Subverts Salicylic Acid-Mediated Citrus Immunity via a Two-Pronged Impairment of CsTCP15 Dimerization. [PDF]

Plant Biotechnol J
ABSTRACT Citrus Huanglongbing (HLB), a devastating disease caused by the unculturable bacterium ‘Candidatus Liberibacter asiaticus’ (CLas), poses a severe threat to global citrus production. CLas secretes effectors to suppress host immune responses and facilitate its colonisation. Previously, the CLas effector SECP8 (CLIBASIA_05330) has been identified

The ABC transporters in Candidatus Liberibacter asiaticus [PDF]

Proteins: Structure, Function, and Bioinformatics, 2012
AbstractCandidatus Liberibacter asiaticus (Ca. L. asiaticus) is a Gram‐negative bacterium and the pathogen of Citrus Greening disease (Huanglongbing, HLB). As a parasitic bacterium, Ca. L. asiaticus harbors ABC transporters that play important roles in exchanging chemical compounds between Ca. L. asiaticus and its host.
