Citrus huanglongbing: validation of Real-Time PCR (qPCR) for the detection of Candidatus Liberibacter asiaticus and Candidatus Liberibacter americanus in Colombia [PDF]

Agronomía Colombiana, 2014
Citrus huanglongbing (HLB) is the most destructive citrus disease. Two of the three known HLB-associated Candidatus Liberibacter species were recently found to be present in the Americas.

Unique features of a Japanese 'Candidatus Liberibacter asiaticus' strain revealed by whole genome sequencing. [PDF]

PLoS ONE, 2014
Citrus greening (huanglongbing) is the most destructive disease of citrus worldwide. It is spread by citrus psyllids and is associated with phloem-limited bacteria of three species of α-Proteobacteria, namely, 'Candidatus Liberibacter asiaticus', 'Ca. L.

The transcriptional activator LdtR from 'Candidatus Liberibacter asiaticus' mediates osmotic stress tolerance.

PLoS Pathogens, 2014
The causal agent of Huanglongbing disease, 'Candidatus Liberibacter asiaticus', is a non-culturable, gram negative, phloem-limited α-proteobacterium. Current methods to control the spread of this disease are still limited to the removal and destruction ...

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.

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.

'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

‘Candidatus Liberibacter asiaticus’ secretory protein SDE5640 activates host autophagy dependent on PSMD10 to mediate PBA1 degradation [PDF]

Plant J
Significance Statement In healthy citrus cells, CsPSMD10 directly binds CsATG8 and targets it for ubiquitin‐dependent degradation by the intact 26S proteasome, maintaining low free CsATG8 levels and suppressing autophagy to preserve immune homeostasis.
