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

The flagella of ‘ Candidatus Liberibacter asiaticus’ and its movement in planta [PDF]

Molecular Plant Pathology, 2019
Summary Citrus huanglongbing (HLB) is the most devastating citrus disease worldwide. ‘ Candidatus Liberibacter asiaticus’ (Las) is the most prevalent HLB causal agent that is yet to be cultured.

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

“Candidatus Liberibacter asiaticus” Prophage Late Genes May Limit Host Range and Culturability [PDF]

Applied and Environmental Microbiology, 2014
ABSTRACT “ Candidatus Liberibacter asiaticus” is an uncultured alphaproteobacterium that systemically colonizes its insect host both inter- and intracellularly and also causes a severe, crop-destroying disease of citrus called huanglongbing, or citrus “greening.” In planta , “

Developing epidemiological preparedness for a plant disease invasion: Modelling citrus huánglóngbìng in the European Union

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1403-1423, September 2025.
Huánglóngbìng (HLB) is a bacterial disease of citrus that has significantly impacted Brazil and the United States, although citrus production in the Mediterranean Basin remains unaffected. By developing a mathematical model of spread in Spain, we tested surveillance and control strategies before any future HLB entry in the EU.

Differential water and imidacloprid transport under unsaturated Florida citrus field conditions

Vadose Zone Journal, Volume 24, Issue 5, September/October 2025.
Abstract Citrus production in Florida declined in the past 20 years by >72% due to citrus greening disease which is vectored by Asian citrus psyllid (ACP). Extensive use of pesticides such as imidacloprid (IDP) to manage ACP raises concerns of environmental pollution to shallow groundwater in citrus orchards dominated by sandy soils.
