Names
Ca. ARS69
Abstract
Abstract  The Gemmatimonadota phylum has been widely detected in diverse natural environments, yet their specific ecological roles in many habitats remain poorly investigated. Similarly, the Candidatus ARS69 phylum has been identified only in a few habitats, and literature on their metabolic functions is relatively scarce. In the present study, we investigated the ecological significance of phyla Ca. ARS69 and Gemmatimonadota in the Arctic glacier foreland (GF) e

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

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

ABA-CsABI5-CsCalS11 Module Upregulates Callose Deposition of Citrus Infected with Candidatus Liberibacter asiaticus

Ca. Liberibacter asiaticus
Abstract
Abstract Huanglongbing (HLB) primarily caused by Candidatus Liberibacter asiaticus (CLas) has been threatening citrus production globally. Under HLB conditions, an excessive accumulation of the polysaccharide callose in citrus phloem occurs, leading to phloem blockage and starch accumulation in leaves. The callose production is controlled by callose synthases (CalS), which have multiple members within plants. However, the knowledge of callose production in the citrus upon infectio

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

Ca. Liberibacter asiaticus
Abstract
Abstract 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. Endolysins from bacteriophages are a possible option for disease resistance in plant breeding. Here, we report improvement of citrus resistance to HLB and citrus canker using the LasLYS1 and LasLYS2 endolysins from CaLas. LasLYS2 demonstrated bactericidal efficacy against several Rhi

Candidatus Subterrananammoxibiaceae,” a New Anammox Bacterial Family in Globally Distributed Marine and Terrestrial Subsurfaces

Citation

Names
Ca. Subterrananammoxibiaceae
Abstract
Microorganisms called anammox bacteria are efficient in removing bioavailable nitrogen from many natural and human-made environments. They exist in almost every anoxic habitat where both ammonium and nitrate/nitrite are present.

Candidatus Nealsonbacteria” Are Likely Biomass Recycling Ectosymbionts of Methanogenic Archaea in a Stable Benzene-Degrading Enrichment Culture

Names
Ca. Nealsonbacteria
Abstract
An anaerobic microbial enrichment culture was used to study members of candidate phyla that are difficult to grow in the lab. We were able to visualize tiny “ Candidatus Nealsonbacteria” cells attached to a large Methanothrix cell, revealing a novel episymbiosis.
