Prophage-Encoded Peroxidase in ‘Candidatus Liberibacter asiaticus’ Is a Secreted Effector That Suppresses Plant Defenses

Molecular Plant-Microbe Interactions, 2015
‘Candidatus Liberibacter asiaticus’ is transmitted by psyllids and causes huanglongbing (HLB), a lethal disease of citrus. Most pathogenic ‘Ca. L. asiaticus’ strains carry two nearly identical prophages similar to SC1 and SC2 in strain UF506.

Risk Evaluation and Molecular Characterisation of AtNPR1 Transgenic Citrus Lines Tolerant to Citrus Greening Disease

Plant Biotechnology Journal, Volume 24, Issue 3, Page 1223-1233, March 2026.
ABSTRACT Citrus greening disease, or Huanglongbing (HLB), has caused devastating losses to citrus production in Florida, with yields declining by over 90% since 2005. Despite extensive efforts, no sustainable solution has been widely effective. Here, transgenic ‘Hamlin’ sweet orange lines engineered to constitutively express the Arabidopsis NPR1 ...

High‐efficiency genome‐editing, transgene evaluation, and antimicrobial efficacy testing using Citrus medica L. hairy roots

The Plant Journal, Volume 125, Issue 4, February 2026.
Significance Statement Huanglongbing (HLB) or citrus greening disease threatens global citrus production, yet progress toward effective resistance strategies has been limited by the causal pathogen's unculturable nature and the difficulty of transforming citrus plants.

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.

Yellow canopy syndrome of sugarcane: A review of current knowledge and future research directions

Annals of Applied Biology, Volume 188, Issue 1, Page 48-63, January 2026.
Yellow Canopy Syndrome (YCS) is a complex issue affecting commercial sugarcane in Australia, first identified in Far North Queensland over a decade ago. It has spread across most cane‐growing regions in Queensland and poses a significant threat to the global sugarcane industry.

Thermosensory TRPV Heterotetramers Drive Seasonal Polyphenism: Molecular Basis of CcIav/CcNan‐PKCα‐AKH/AKHR Signaling in Pear Psyllid Morph Transition

Advanced Science, Volume 12, Issue 45, December 4, 2025.
At 2 5 °C, thermal activation initiates: i) CcIav/CcNan heterotetramer assembly → Ca2⁺ influx; ii) CcPKCα phosphorylation → AKH signaling potentiation; iii) CcAKH1 binding to membrane‐localized CcAKHR → energy mobilization (lipid catabolism/glycogenolysis) and vitellogenin transport via follicular patency; iv) Oocyte maturation → summer‐form nymph ...

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

Climate Change Drives the Distribution of Insect Vectors for GLRaV‐3 on a Global Scale

Ecology and Evolution, Volume 15, Issue 10, October 2025.
The distribution range of seven insect vectors of GLRaV‐3 were predicted by MaxEnt model. Thermal conditions were a vital factor constraining the potential distribution ranges of all vector insects. Centroid shifts suggested that the potential distribution range of soft scale will move northward under climate change. Our study provides implications for

Characterization of copy numbers of 16S rDNA and 16S rRNA of Candidatus Liberibacter asiaticus and the implication in detection in planta using quantitative PCR

BMC Research Notes, 2009
Background Citrus Huanglongbing (HLB) is one of the most devastating diseases on citrus and is associated with Candidatus Liberibacter spp.. The pathogens are phloem limited and have not been cultured in vitro.

Belief in neighbor behavior and confidence in scientific information as barriers to cooperative disease control

American Journal of Agricultural Economics, Volume 107, Issue 5, Page 1457-1476, October 2025.
Abstract Recent public health events have brought to the forefront the challenges of incorporating collective action behaviors and information seeking and processing behaviors to motivate personal protections to an environmental risk. The economic and social costs of large‐scale spread of disease when there is no cure for the disease, only preventative
