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.

Neuropeptide Ecdysis-Triggering Hormone and Its Receptor Mediate the Fecundity Improvement of 'Candidatus Liberibacter Asiaticus'-Infected Diaphorina citri Females and CLas Proliferation. [PDF]

Adv Sci (Weinh)
In CLas‐infected D. citri, CLas lowers 20E levels initially, relieving the suppression of ETH release. The subsequent increase in ETH levels upregulates its receptor DcETHR and activates the JH signaling pathway. The signaling cascade of 20E‐ETH/ETHR‐JH along with miR‐210, targeting DcETHR, boost female fecundity in CLas+ D.

‘Candidatus Liberibacter asiaticus’ Multimeric LotP Mediates Citrus sinensis Defense Response Activation [PDF]

Frontiers in Microbiology, 2021
‘Candidatus Liberibacter asiaticus’ is known as the most pathogenic organism associated with citrus greening disease. Since its publicized emergence in Florida in 2005, ‘Ca. L. asiaticus’ remains unculturable. Currently, a limited number of potential disease effectors have been identified through in silico analysis. Therefore, these potential effectors

Gene regulatory networks elucidating huanglongbing disease mechanisms. [PDF]

, 2013
Next-generation sequencing was exploited to gain deeper insight into the response to infection by Candidatus liberibacter asiaticus (CaLas), especially the immune disregulation and metabolic dysfunction caused by source-sink disruption.

Alternative Tissue Sampling for Improved Detection of Candidatus Liberibacter asiaticus. [PDF]

Plants (Basel), 2023
Early detection and prompt response are key factors in the eradication of ‘huanglongbing’ (HLB) in California. Currently, qPCR testing of leaf tissue guides the removal of infected trees. However, because of the uneven distribution of ‘Candidatus Liberibacter asiaticus’ (CLas) in an infected tree and asymptomatic infection, selecting the best leaves to

Genome Sequence Resource of ‘Candidatus Liberibacter asiaticus’ from Thailand [PDF]

Plant Disease, 2020
‘Candidatus Liberibacter asiaticus’ (Las) is an unculturable α-proteobacterium associated with citrus huanglongbing (HLB), a devastating disease currently threatening the citrus industry worldwide. Here, we present the genome sequence of Las strain TaiYZ2 from an HLB-affected pomelo tree in Hat Yai district, Songkhla Province, Thailand.

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.

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.
