Prophage Diversity of ‘CandidatusLiberibacter asiaticus’ Strains in California [PDF]

Phytopathology®, 2019
Huanglongbing (HLB) is a highly destructive citrus disease and is associated with a nonculturable bacterium, ‘Candidatus Liberibacter asiaticus’. ‘Ca. L. asiaticus’ in the United States was first found in Florida in 2005 and is now endemic there. In California, ‘Ca. L.

Ultrastructures of Candidatus Liberibacter asiaticus and its damage in huanglongbing (HLB) infected citrus [PDF]

, 2009
Candidatus Liberibacter asiaticus is not cultured in media and there is insufficient information on the movement of the pathogen in citrus plants. Samples were collected from infected citrus plants grown in Ulu Pakar, Terengganu, Malaysia and they show ...

Modeling ‘Candidatus Liberibacter asiaticus’ Movement Within Citrus Plants

Phytopathology®, 2021
The phloem-limited ‘Candidatus Liberibacter asiaticus’ (Las) causes huanglongbing, a destructive citrus disease. Graft-inoculated potted plants were used to assess Las speed of movement in phloem in the greenhouse, and the impacts of temperature on plant colonization in growth-chamber experiments. For assessment of Las speed, plants were inoculated at

An endolysin gene from Candidatus Liberibacter asiaticus confers dual resistance to huanglongbing and citrus canker

Horticulture Research, 2023
The most damaging citrus diseases are Huanglongbing (HLB) and citrus canker, which are caused by Candidatus Liberibacter asiaticus (CaLas) and Xanthomonas citri pv. citri (Xcc), respectively.

Alternative Tissue Sampling for Improved Detection of Candidatus Liberibacter asiaticus

Plants, 2023
Early detection and prompt response are key factors in the eradication of ‘huanglongbing’ (HLB) in California. Currently, qPCR testing of leaf tissue guides the removal of infected trees. However, because of the uneven distribution of ‘Candidatus Liberibacter asiaticus’ (CLas) in an infected tree and asymptomatic infection, selecting the best leaves to

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

Changes in Variable Number of Tandem Repeats in 'Candidatus Liberibacter asiaticus' through Insect Transmission. [PDF]

PLoS ONE, 2015
Citrus greening (huanglongbing) is the most destructive citrus disease worldwide. The disease is associated with three species of 'Candidatus Liberibacter' among which 'Ca. Liberibacter asiaticus' has the widest distribution. 'Ca. L.
