Snow Exclusion Does Not Affect Soil Ammonia-Oxidizing Bacteria and Archaea Communities

open access: yes, 2022
Soil ammonia-oxidizing microorganisms play important roles in nitrogen (N) cycling in cold ecosystems, but how changes in snow cover will affect their distribution and associated functional characteristics remains unclear.

Diversity and abundance of ammonia-oxidizing archaea in the Dongjiang River, China

open access: yesMicrobiological Research, 2011
Nitrification in aquatic ecosystems plays a crucial role in the global nitrogen cycling. It has been widely accepted that ammonia-oxidizing bacteria (AOB) are responsible for nitrification. However, this concept is currently challenged by the ubiquity of ammonia-oxidizing archaea (AOA) in various environments, such as in aquatic and terrestrial ...

Benthic Ammonia Oxidizers Differ in Community Structure and Biogeochemical Potential Across a Riverine Delta

open access: yesFrontiers in Microbiology, 2015
Nitrogen pollution in coastal zones is a widespread issue, particularly in ecosystems with urban or agricultural watersheds. California’s Sacramento-San Joaquin Delta, at the landward reaches of San Francisco Bay, is highly impacted by both agricultural ...

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

open access: yes, 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.

Nitrifier Gene Abundance and Diversity in Sediments Impacted by Acid Mine Drainage

open access: yesFrontiers in Microbiology, 2017
Extremely acidic and metal-rich acid mine drainage (AMD) waters can have severe toxicological effects on aquatic ecosystems. AMD has been shown to completely halt nitrification, which plays an important role in transferring nitrogen to higher organisms ...

Ammonia-oxidizing archaea use the most energy-efficient aerobic pathway for CO2 fixation

open access: yes, 2014
Archaea of the phylum Thaumarchaeota are among the most abundant prokaryotes on Earth and are widely distributed in marine, terrestrial, and geothermal environments.

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

open access: yes, 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.

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

open access: yesAgronomy
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 and community structure of ammonia oxidizing archaea in long term fertilized paddy fields

open access: yes, 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
