Nitrogen regulation of protein–protein interactions and transcript levels of GlnK PII regulator and AmtB ammonium transporter homologs in Archaea [PDF]

, 2013
Gene homologs of GlnK PII regulators and AmtB-type ammonium transporters are often paired on prokaryotic genomes, suggesting these proteins share an ancient functional relationship.

Diversity and community structure of ammonia oxidizing archaea in long term fertilized paddy fields

, 2017
Long-term experiments involving different fertilization practices have been conducted at Miryang research station, South Korea since 1967 for the purpose of studying how varying fertilization regimes influence soil parameters and crop yield. By utilizing

Response of Nitrification and Crop Yield to the Presence of NBPT and DCD in a Wheat-Corn Double Cropping System

Agronomy
The excessive application of nitrogen fertilizer aggravated the loss of nitrogen in farmland and exerted detrimental effects on the soil and water environment. Examining the effects of N-(n-Butyl)thiophosphoric triamide (NBPT) and nitrification inhibitor

Diversity, Physiology, and Niche Differentiation of Ammonia-Oxidizing Archaea [PDF]

, 2012
Nitrification, the aerobic oxidation of ammonia to nitrate via nitrite, has been suggested to have been a central part of the global biogeochemical nitrogen cycle since the oxygenation of Earth.

Data from: Vascular plants mediate the effects of aridity and soil properties on ammonia-oxidizing bacteria and archaea

, 2013
An integrated perspective of the most important factors driving the abundance of ammonia-oxidizing bacteria (AOB) and archaea (AOA) in natural ecosystems is lacking, especially in drylands.

Membraneless channels sieve cations in ammonia-oxidizing marine archaea. [PDF]

Nitrosopumilus maritimus is an ammonia-oxidizing archaeon that is crucial to the global nitrogen cycle1,2. A critical step for nitrogen oxidation is the entrapment of ammonium ions from a dilute marine environment at the cell surface and their subsequent

Diversity and mode of transmission of ammonia-oxidizing archaea in marine sponges

, 2008
The model marine crenarchaeote ‘Cenarchaeum symbiosum’ is until now the only ammonia-oxidizing archaeon known from a marine sponge. Here, phylogenetic analyses based on the 16S rRNA and ammonia monooxygenase subunit A (amoA) genes revealed the presence ...

Comammox Nitrospira abundance and contribution to nitrification in a forested landscape

Ecosphere
Nitrification in terrestrial ecosystems is mediated by NH4+‐oxidizing bacteria (AOB) and archaea (AOA). Presently, we understand relatively little about how physiological capacities and environmental tolerances influence their community composition, and ...
