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

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

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.

'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

Infection Patterns of a Liberibacter Associated with Macrohomotoma gladiata, a Psyllid Feeding on Ficus microcarpa

Microbiology Spectrum, 2022
Almost all known Liberibacters can be transmitted by psyllids. This suggests that there is a coevolutionary relationship between these two groups of organisms. However, detailed investigation of Liberibacters and psyllids have often focused on only a few

PCR-based detection and phylogenetic analysis of Candidatus Liberibacter asiaticus in citrus orchards across Nepal. [PDF]

PLoS ONE
Citrus greening disease, also known as huanglongbing (HLB), is caused by the gram-negative α-proteobacteria Candidatus Liberibacter species. This disease poses a significant threat to citrus production worldwide, including in Nepal.

Alterations of Candidatus Liberibacter asiaticus-Associated Microbiota Decrease Survival of Ca. L. asiaticus in in vitro Assays

Frontiers in Microbiology, 2018
Phloem-inhabiting bacterial phytopathogens often have smaller genomes than other bacterial phytopathogens. It is thought that they depend on both other phloem microbiota and phloem nutrients for colonization of the host. However, the mechanism underlying

Dopamine and its receptor DcDop2 are involved in the coevolution between ‘Candidatus Liberibacter asiaticus’ and Diaphorina citri [PDF]

eLife
‘Candidatus Liberibacter asiaticus’ (CLas), the causal agent of citrus huanglongbing, is transmitted by the Asian citrus psyllid Diaphorina citri. While CLas-positive (CLas+) females exhibit increased fecundity and metabolic demands, their neuroendocrine
