Optimization of vqPCR for Reliable Detection of Viable Candidatus Liberibacter asiaticus in Citrus

HortScience, 2022
Citrus Huanglongbing (HLB, also known as “citrus greening”), an important disease worldwide, is associated with three species of phloem-limited Candidatus liberibacter, of which Candidatus L.

‘Candidatus Liberibacter Asiaticus’ Effector SECP8 Subverts Salicylic Acid‐Mediated Citrus Immunity via a Two‐Pronged Impairment of CsTCP15 Dimerization

Plant Biotechnology Journal, EarlyView.
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

Confirmation of the Sequence of ‘Candidatus Liberibacter asiaticus’ and Assessment of Microbial Diversity in Huanglongbing-Infected Citrus Phloem Using a Metagenomic Approach

Molecular Plant-Microbe Interactions, 2009
The citrus disease Huanglongbing (HLB) is highly destructive in many citrus-growing regions of the world. The putative causal agent of this disease, ‘Candidatus Liberibacter asiaticus’, is difficult to culture, and Koch's postulates have not yet been ...

A Bacterial Effector Hijacks NBR1 to Modulate Both Autophagy and Ubiquitination‐Mediated Degradation That Promotes Bacterial Infection

Plant Biotechnology Journal, EarlyView.
ABSTRACT Autophagy and the ubiquitin/26S proteasome system (UPS) play critical roles in the immune defence of the host against pathogen invasion. As a countermeasure, pathogens deploy effector proteins to subvert or hijack autophagy and UPS processes.

Curent Situation of “Candidatus Liberibacter asiaticus” in Guangdong, China, Where Citrus Huanglongbing Was First Described

Journal of Integrative Agriculture, 2012
Citrus Huanglongbing (HLB, yellow shoot disease) was first observed in the coastal Chaoshan Plain of Guangdong Province, China, in the late 19th century based on descriptions of yellow shoot symptoms.

Psyllid Cysteine Cathepsins Directly Cleave the Outer Membrane Protein BamD of Citrus Huanglongbing Pathogen

Plant Biotechnology Journal, EarlyView.
ABSTRACT Candidatus Liberibacter asiaticus (CLas), the causative agent of citrus Huanglongbing (HLB), is transmitted by Asian citrus psyllid, Diaphorina citri; however, the role of the insect's immune effectors in defending against CLas remains poorly understood. This study reveals that D.

CitPH4 Confers Resistance to Citrus Canker by Activating Papain‐Like Cysteine Protease

Plant Biotechnology Journal, EarlyView.
ABSTRACT Citrus canker, a devastating disease caused by Xanthomonas citri subsp. citri (Xcc), poses a significant threat to global citrus production due to the high susceptibility of nearly all commercial citrus cultivars to it. Although transcription factor Citrus PH4 (CitPH4) is well known for regulating fruit acidity, its potential role in plant ...

Soil beneficial bacteria: Harnessing tools for optimizing citrus growth and soil health in pH‐stressed soils

Journal of Environmental Quality, Volume 55, Issue 2, March/April 2026.
Abstract Rhizosphere bacteria can support crop production by promoting plant health, soil fertility, and resilience to biotic and abiotic stresses. However, the potential role of soil‐beneficial bacteria, particularly plant growth‐promoting rhizobacteria (PGPR), remains inadequately explored in citrus production grown on pH‐stressed soil.
