An Improved Reference Gene for Detection of “Candidatus Liberibacter asiaticus” Associated with Citrus Huanglongbing by qPCR and Digital Droplet PCR Assays

Names
Ca. Liberibacter asiaticus
Abstract
Citrus huanglongbing (HLB) disease associated with the ‘Candidatus Liberibacter asiaticus’ (CLas) bacterium has caused significant financial damage to many citrus industries. Large-scale pathogen surveys are routinely conducted in California to detect CLas early in the disease cycle by lab-based qPCR assays. We have developed an improved reference gene for the sensitive detection of CLas from plants in diagnostic duplex qPCR and analytical digital droplet PCR (ddPCR) assays. The mitochondrial cy

Exogenous Application of Polycationic Nanobactericide on Tomato Plants Reduces the Candidatus Liberibacter Solanacearum Infection

Citation

Names
“Liberibacter solanacearum” Liberibacter
Abstract
Candidatus Liberibacter solanacearum (CaLso) is associated with diseases in tomato crops and transmitted by the tomato psyllid Bactericera cockerelli. A polymeric water-dispersible nanobactericide (PNB) was evaluated against CaLso as a different alternative. PNB is a well-defined polycationic diblock copolymer designed to permeate into the vascular system of plants. Its assessment under greenhouse conditions was carried out with tomato plants previously infected with CaLso. Using a concentration

A Glycolipid Glycosyltransferase with Broad Substrate Specificity from the Marine Bacterium “ Candidatus Pelagibacter sp.” Strain HTCC7211

Citation
Wei et al. (2021). Applied and Environmental Microbiology 87 (14)
Names
Ca. Pelagibacter
Abstract
The bilayer formed by membrane lipids serves as the containment unit for living microbial cells. In the marine environment, it has been firmly established that phytoplankton and heterotrophic bacteria can substitute phospholipids with nonphosphorus sugar-containing glycoglycerolipids in response to phosphorus limitation.

Sifarchaeota ,” a Novel Asgard Phylum from Costa Rican Sediment Capable of Polysaccharide Degradation and Anaerobic Methylotrophy

Citation
Farag et al. (2021). Applied and Environmental Microbiology 87 (9)
Names
“Sifarchaeum subterraneum” “Sifarchaeum” Ca. Sifarchaeum marinoarchaea Ca. Sifarchaeum subterraneus “Sifarchaeota”
Abstract
The exploration of deep marine sediments has unearthed many new lineages of microbes. The finding of this novel phylum of Asgard archaea is important, since understanding the diversity and evolution of Asgard archaea may inform also about the evolution of eukaryotic cells. The comparison of metabolic potentials of the Asgard archaea can help inform about selective pressures the lineages have faced during evolution.

New Cross-Talks between Pathways Involved in Grapevine Infection with ‘Candidatus Phytoplasma solani’ Revealed by Temporal Network Modelling

Citation
Škrlj et al. (2021). Plants 10 (4)
Names
Ca. Phytoplasma solani
Abstract
Understanding temporal biological phenomena is a challenging task that can be approached using network analysis. Here, we explored whether network reconstruction can be used to better understand the temporal dynamics of bois noir, which is associated with ‘Candidatus Phytoplasma solani’, and is one of the most widespread phytoplasma diseases of grapevine in Europe. We proposed a methodology that explores the temporal network dynamics at the community level, i.e., densely connected subnetworks. T

“ Candidatus Liberibacter asiaticus” Secretes Nonclassically Secreted Proteins That Suppress Host Hypersensitive Cell Death and Induce Expression of Plant Pathogenesis-Related Proteins

Citation
Du et al. (2021). Applied and Environmental Microbiology 87 (8)
Names
Ca. Liberibacter asiaticus
Abstract
In this study, we present a combined computational and experimental methodology that allows a rapid and efficient identification of the ncSecPs from bacteria, in particular the unculturable bacteria like CLas. Meanwhile, the study determined that a number of CLas ncSecPs suppressed HR-based cell death, and thus indicated a novel role for the bacterial ncSecPs in extracellular milieu.

Oxidative Stress and Antioxidative Activity in Leaves and Roots of Carrot Plants Induced by Candidatus Phytoplasma Solani

Citation
Mitrovic et al. (2021). Plants 10 (2)
Names
Ca. Phytoplasma Ca. Phytoplasma solani
Abstract
The present study examined the effects of Candidatus Phytoplasma solani infection on antioxidative metabolism in leaves and roots of carrot (Daucus carota L.). Disease symptoms appeared at the end of June in the form of the chlorosis on some of the leaves, which became intensely red one week later, while the previously healthy leaves from the same branch becme chlorotic. A few days later, all leaves from the infected leaf branch were intensely red. Infected plants also had slower growth compared

The Actin Cytoskeleton Mediates Transmission of “ Candidatus Liberibacter solanacearum” by the Carrot Psyllid

Citation

Names
“Liberibacter solanacearum”
Abstract
Plant diseases caused by vector-borne pathogens are responsible for tremendous losses and threaten some of the most important agricultural crops. A good example is the citrus greening disease, which is caused by bacteria of the genus Liberibacter and is transmitted by psyllids; it has devastated the citrus industry in the United States, China, and Brazil.
