Transcriptomic and Metabolomic Analyses of Diaphorina citri Kuwayama Infected and Non-infected With Candidatus Liberibacter Asiaticus

Names
Ca. Liberibacter asiaticus Liberibacter
Abstract
The Asian citrus psyllid Diaphorina citri is the transmission vector of Huanglongbing (HLB), a devastating disease of citrus plants. The bacterium “Candidatus Liberibacter asiaticus” (CLas) associated with HLB is transmitted between host plants by D. citri in a circulative manner. Understanding the interaction between CLas and its insect vector is key for protecting citrus cultivation from HLB damage. Here, we used RNA sequencing and liquid chromatography-mass spectrometry (LC-MS) to analyze the

Production and Excretion of Polyamines To Tolerate High Ammonia, a Case Study on Soil Ammonia-Oxidizing Archaeon “ Candidatus Nitrosocosmicus agrestis”

Names
Ca. Nitrosocosmicus Ca. Nitrosocosmicus agrestis
Abstract
Ammonia tolerance of AOA is usually much lower than that of the AOB, which makes the AOB rather than AOA a predominant ammonia oxidizer in agricultural soils, contributing to global N 2 O emission. Recently, some AOA species from the genus “ Ca. Nitrosocosmicus” were also found to have high ammonia tolerance.

Genomes of the “ Candidatus Actinomarinales” Order: Highly Streamlined Marine Epipelagic Actinobacteria

Citation

Abstract
Microbiology is in a new age in which sequence databases are primary sources of information about many microbes. However, in-depth analysis of environmental genomes thus retrieved is essential to substantiate the new knowledge.

Sec-Delivered Effector 1 (SDE1) of ‘Candidatus Liberibacter asiaticus’ Promotes Citrus Huanglongbing

Citation
Clark et al. (2020). Molecular Plant-Microbe Interactions® 33 (12)
Names
Ca. Liberibacter asiaticus
Abstract
Sec-delivered effector 1 (SDE1) from the huanglongbing (HLB)-associated bacterium ‘Candidatus Liberibacter asiaticus’ was previously characterized as an inhibitor of defense-related, papain-like cysteine proteases in vitro and in planta. Here, we investigated the contributions of SDE1 to HLB progression. We found that SDE1 expression in the model plant Arabidopsis thaliana caused severe yellowing in mature leaves, reminiscent of both ‘Ca. L. asiaticus’ infection symptoms and accelerated leaf se

Comparative Genomics Screen Identifies Microbe-Associated Molecular Patterns from ‘Candidatus Liberibacter’ spp. That Elicit Immune Responses in Plants

Abstract
Citrus huanglongbing (HLB), caused by phloem-limited ‘Candidatus Liberibacter’ bacteria, is a destructive disease threatening the worldwide citrus industry. The mechanisms of pathogenesis are poorly understood and no efficient strategy is available to control HLB. Here, we used a comparative genomics screen to identify candidate microbe-associated molecular patterns (MAMPs) from ‘Ca. Liberibacter’ spp. We identified the core genome from multiple ‘Ca. Liberibacter’ pathogens, and searched for co
