Adipokinetic hormone signaling mediates the fecundity of Diaphorina citri infected by ‘Candidatus Liberibacter asiaticus’

Ca. Liberibacter asiaticus
Abstract
Diaphorina citri is the primary vector of the bacterium, ‘ Candidatus Liberibacter asiaticus’ ( C Las) associated with the severe Asian form of huanglongbing. C Las-positive D. citri are more fecund than their C Las-negative counterparts and require extra energy expenditure. Therefore, understanding the molecular mechanisms linking metabolism and reproduction is of particular importance. In this present study, we found adipokinetic hormone ( DcAKH ) and its receptor ( DcAKHR ) were essenti

Extremely acidic proteomes and metabolic flexibility in bacteria and highly diversified archaea thriving in geothermal chaotropic brines

Abstract
Few described archaeal, and fewer bacterial, lineages thrive at salt-saturating conditions, such as solar saltern crystallizers (salinity above 30%-w/v). They accumulate molar K+ cytoplasmic concentrations to maintain osmotic balance ("salt-in" strategy), and have proteins adaptively enriched in negatively charged, acidic amino acids. Here, we analyzed metagenomes and metagenome-assembled genomes (MAGs) from geothermally influenced hypersaline ecosystems with increasing chaotropicity in the Dana

Metabolomic Profiling Reveals the Quality Variations in Citri Reticulatae Pericarpium (Citrus reticulata Blanco cv. Chachiensis) with Different Storage Ages in Response to “Candidatus Liberibacter Asiaticus” Infection

Names
Liberibacter Ca. Liberibacter asiaticus
Abstract
Citri Reticulatae Pericarpium, especially the pericarp of Citrus reticulata Blanco cv. Chachiensis (PCRC), is an important edible and medicinal ingredient for health and pharmacological properties. Citrus Huanglongbing, a devastating disease that currently threatens the citrus industry worldwide, is caused by a phloem-limited alpha-proteobacterium, “Candidatus Liberibacter asiaticus” (CLas). The industry of cultivar Chachiensis has been suffering from HLB. Although HLB affected the quality of ci

Towards the completion of Koch's postulates for the citrus huanglongbing bacterium, Candidatus Liberibacter asiaticus

Citation
Zheng et al. (2024). Horticulture Research 11 (3)
Names
Ca. Liberibacter asiaticus
Abstract
Abstract Candidatus Liberibacter asiaticus (Las) is one of the causal agents of huanglongbing (HLB), the most devastating disease of citrus worldwide. Due to the intracellular lifestyle and significant genome reduction, culturing Las in vitro has proven to be extremely challenging. In this study, we optimized growth conditions and developed a semi-selective medium based on the results of nutritional and antibiotic screening assays. Using these optimized conditions, we were able to

Molecular Detection of Candidatus Anaplasma camelii in Naturally Infected Dromedary Camels (Camelus dromedarius) in Abu Dhabi Emirate, United Arab Emirates, 2019–2023

Names
Ca. Anaplasma camelii
Abstract
The recent emergence of anaplasmosis in camels has raised global interest in the pathogenicity and zoonotic potential of the pathogen causing it and the role of camels as reservoir hosts. In the United Arab Emirates (UAE), molecular studies and genetic characterization of camel-associated Anaplasma species are limited. This study aimed to characterize molecularly Anaplasmataceae strains circulating in dromedary camels in the UAE. Two hundred eighty-seven whole-blood samples collected from dromed

Unraveling and quantifying “CandidatusSaccharibacteria”:in silicoand experimental evaluation of V3-V4 16S rRNA metagenomics and qPCR protocols

Citation
Papaleo et al. (2024).
Names
Ca. Saccharibacteria
Abstract
AbstractBackgroundCandidate Phyla Radiation (CPR) is a large monophyletic group thought to cover about 25% of bacterial diversity. Due to peculiar characteristics and unusual 16S rRNA gene structure, they are often under-represented or lost in 16S rRNA-based microbiota surveys. Among CPR, “CandidatusSaccharibacteria” is a phylum experimentally found to modulate the immune response and enriched in the oral microbiota of subjects suffering from several immune-mediated disorders, e.g. food allergie

Molecular detection and multilocus sequence analysis of Candidatus Phytoplasma solani-related strains infecting potato and sugar beet plants in Southern Germany

Abstract
Abstract Syndrome ‘basses richesses’ (SBR) disease in sugar beet caused by two phloem-limited pathogens, 'Candidatus Arsenophonus phytopathogenicus' and 'Candidatus Phytoplasma solani' is a fastspreading disease in Central Europe. The planthopper vector, Pentastiridius leporinus (Cixiidae), has recently expanded its host range to potato in Germany. However, the genetic diversity of 'Ca P. solani' in potato and possible association to SBR phytoplasma is unknown. In this study we charachte
