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

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.

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.

'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

Beneath the Bark: Molecular Determinants of Adaptation and Infection in Bacterial Pathogens of Woody Hosts. [PDF]

Mol Plant Pathol
Bacterial pathogens colonise woody hosts by integrating metabolic adaptation, effector‐mediated immune suppression, cell wall remodelling and EPS‐ and toxin‐supported persistence. ABSTRACT Bacterial pathogens of woody plants represent a pervasive yet underexplored threat to global agriculture and forestry, causing devastating diseases in fruit trees ...

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.

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

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.

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.
