Identifying Potential Mechanisms Enabling Acidophily in the Ammonia-Oxidizing Archaeon “Candidatus Nitrosotalea devanaterra”

Citation

Names
Ca. Nitrosotalea devanaterra
Abstract
ABSTRACT Ammonia oxidation is the first and rate-limiting step in nitrification and is dominated by two distinct groups of microorganisms in soil: ammonia-oxidizing archaea (AOA) and ammonia-oxidizing bacteria (AOB). AOA are often more abundant than AOB and dominate activity in acid soils. The mechanism of ammonia oxidation under acidic conditions has been a long-standing paradox. While high rates of ammonia oxidation are frequently measured in acid soils, cultivated ammon

“Candidatus Finniella” (Rickettsiales, Alphaproteobacteria), Novel Endosymbionts of Viridiraptorid Amoeboflagellates (Cercozoa, Rhizaria)

Citation
Hess et al. (2016). Applied and Environmental Microbiology 82 (2)
Names
“Finniella inopinata” “Finniella lucida” “Finniella” “Parafinniella”
Abstract
ABSTRACT The Rickettsiales ( Alphaproteobacteria ) are obligate intracellular bacteria that colonize a wide range of eukaryotic hosts, including diverse metazoa and protists. Here, we characterize rickettsial endosymbionts discovered in the cytoplasm of the algivorous amoeboflagellates Viridiraptor invadens and Orciraptor agilis (Viridiraptoridae, Cercozoa, Rhizaria), supplying

Infection Density Dynamics of the Citrus Greening Bacterium “Candidatus Liberibacter asiaticus” in Field Populations of the Psyllid Diaphorina citri and Its Relevance to the Efficiency of Pathogen Transmission to Citrus Plants

Citation
Ukuda-Hosokawa et al. (2015). Applied and Environmental Microbiology 81 (11)
Names
Ca. Liberibacter asiaticus
Abstract
ABSTRACT Huanglongbing, or citrus greening, is a devastating disease of citrus plants recently spreading worldwide, which is caused by an uncultivable bacterial pathogen, “ Candidatus Liberibacter asiaticus,” and vectored by a phloem-sucking insect, Diaphorina citri . We investigated the infection density dynamics of “ Ca . Liberibacter asiaticus” in field populations of D. citri

Metatranscriptomic Analysis of Diminutive Thiomargarita-Like Bacteria (“Candidatus Thiopilula” spp.) from Abyssal Cold Seeps of the Barbados Accretionary Prism

Citation
Jones et al. (2015). Applied and Environmental Microbiology 81 (9)
Names
Ca. Thiophysa Ca. Thiopilula
Abstract
ABSTRACT Large sulfur-oxidizing bacteria in the family Beggiatoaceae are important players in the global sulfur cycle. This group contains members of the well-known genera Beggiatoa , Thioploca , and Thiomargarita but also recently identified and relatively unknown candidate taxa, including “ Candidatus Thiopilula” spp. and “ Ca .
