Dynamics of ‘Candidatus Liberibacter asiaticus’ Growth, Concentrations of Reactive Oxygen Species, and Ion Leakage in Huanglongbing-Positive Sweet Orange

Citation
Pandey et al. (2024). Phytopathology® 114 (5)
Names
Ca. Liberibacter asiaticus
Abstract
Citrus Huanglongbing (HLB) caused by ‘ Candidatus Liberibacter asiaticus’ (CLas) is the most devastating citrus disease worldwide. CLas induces systemic and chronic reactive oxygen species (ROS) production, which has been suggested to be a primary cause of cell death in phloem tissues and subsequent HLB symptoms. Mitigating oxidative stress caused by CLas using horticultural approaches has been suggested as a useful strategy to reduce HLB damages. To provide information regarding the applicatio

Root System Reductions of Grafted ‘Valencia’ Orange Trees Are More Extensive Than Aboveground Reductions after Natural Infection with Candidatus Liberibacter Asiaticus

Citation

Names
Ca. Liberibacter asiaticus Liberibacter
Abstract
Huanglongbing (HLB), which is associated with the phloem-limited bacteria Candidatus Liberibacter asiaticus (CLas), is a devastating disease that affects citrus trees worldwide. Because of the pervasiveness of the bacteria and psyllid vector, the disease is considered endemic in Florida. Although the effects of CLas on tree growth and physiology have been investigated for decades, most studies compared infected and noninfected trees under greenhouse conditions. This study used newly planted fiel

An Inhibitor-Monitorable Single-Tube Duplex Quantitative Real-Time PCR Assay for the Detection of ‘Candidatus Liberibacter asiaticus’

Citation
Huang et al. (2024). Plant Disease 108 (5)
Names
Ca. Liberibacter asiaticus
Abstract
Huanglongbing (HLB) is a citrus infectious disease caused by ‘Candidatus Liberibacter’ spp. Recently, it has begun to spread rapidly worldwide, causing significant losses to the citrus industry. Early diagnosis of HLB relies on quantitative real-time PCR assays. However, the PCR inhibitors found in the nucleic acid extracted from plant materials pose challenges for PCR assays because they may result in false-negative results. Internal standard (IS) can be introduced to establish a single-tube d

Identification of ‘Candidatus Liberibacter asiaticus’, the Huanglongbing Bacterium, in Citrus from Colombia

Citation

Names
Liberibacter Ca. Liberibacter asiaticus
Abstract
‘Candidatus Liberibacter’ spp. are the most prevalent microorganisms in the citrus plant, associated with citrus huanglongbing, which are transmitted by psyllid vectors. In Colombia, the vector Diaphorina citri Kuwayama has been reported in different regions, but ‘Ca. Liberibacter asiaticus’ (CLas) has only been detected in insect vectors, not in citrus host plants. To identify the presence and quantify the pathogen in citrus tissues, we employed a combined strategy that involved three techniqu
