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.

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.

Identification of the genes required for the culture of Liberibacter crescens, the closest cultured relative of the uncultured Liberibacter plant pathogens

Frontiers in Microbiology, 2016
Here Tn5 random transposon mutagenesis was used to identify the essential elements for culturing Liberibacter crescens BT-1 that can serve as antimicrobial targets for the closely related pathogens of citrus, Candidatus Liberibacter asiaticus (Las) and ...

Plant hairy roots enable high throughput identification of antimicrobials against Candidatus Liberibacter spp.

Nature Communications, 2020
The putative causal agent of citrus greening Candidatus Liberibacter asiaticus (CLas) cannot be cultured, which hampers finding new therapies to control this devastating disease. Here, the authors show that hairy roots support CLas propagation and enable

Two plant bacteria, S. meliloti and Ca. Liberibacter asiaticus, share functional znuABC homologues that encode for a high affinity zinc uptake system. [PDF]

PLoS ONE, 2012
The Znu system, encoded for by znuABC, can be found in multiple genera of bacteria and has been shown to be responsible for the import of zinc under low zinc conditions.
