Ammonia-Oxidizer Communities in an Agricultural Soil treated with Contrasting Nitrogen Sources.

Frontiers in Microbiology, 2013
The community of ammonia-oxidizing prokaryotes was examined in an agricultural soil treated for 6 seasons with contrasting nitrogen (N) sources. Molecular tools based on the gene encoding ammonia monooxygenase were used to characterize the ammonia ...

High-throughput analysis of ammonia oxidiser community composition via a novel, amoA-based functional gene array. [PDF]

PLoS ONE, 2012
Advances in microbial ecology research are more often than not limited by the capabilities of available methodologies. Aerobic autotrophic nitrification is one of the most important and well studied microbiological processes in terrestrial and aquatic ...

Exploring Multifunctional Microbial Genes From the Rhizosphere of Allium ampeloprasum Under Different Fertilization Systems

Environmental DNA, Volume 8, Issue 2, March/April 2026.
This study uncovers key multifunctional genes in the rhizosphere of Allium ampeloprasum under varying fertilization systems. This highlights their roles in nutrient cycling, plant growth promotion, and soil health, thereby offering insight for sustainable agricultural sustainability.

The application of high-throughput sequencing technology to analysis of amoA phylogeny and environmental niche specialisation of terrestrial bacterial ammonia-oxidisers

Environmental Microbiome, 2019
Background Characterisation of microbial communities increasingly involves use of high throughput sequencing methods (e.g. MiSeq Illumina) that amplify relatively short sequences of 16S rRNA or functional genes, the latter including ammonia monooxygenase

Niche differentiation of comammox Nitrospira in sediments of the Three Gorges Reservoir typical tributaries, China

Scientific Reports, 2022
Complete ammonia oxidizer (Comammox) can complete the whole nitrification process independently, whose niche differentiation is important guarantee for its survival and ecological function.

Nanocomposite Reduces Volatile and Aqueous Reactive Nitrogen Losses From Soil Compared to Conventional and Alternative Fertilisers

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Reactive nitrogen losses from agriculture contribute substantially to greenhouse gas emissions, water pollution and ecosystem degradation. Controlled‐release fertiliser technologies offer potential solutions, yet few comprehensively evaluate performance across multiple nitrogen loss pathways and soil types.

Pesticide Side Effects in an Agricultural Soil Ecosystem as Measured by amoA Expression Quantification and Bacterial Diversity Changes.

PLoS ONE, 2015
Background and methodsAssessing the effects of pesticide hazards on microbiological processes in the soil is currently based on analyses that provide limited insight into the ongoing processes. This study proposes a more comprehensive approach.

Impact of Irrigation Strategies on Tomato Root Distribution and Rhizosphere Processes in an Organic System. [PDF]

, 2020
Root exploitation of soil heterogeneity and microbially mediated rhizosphere nutrient transformations play critical roles in plant resource uptake. However, how these processes change under water-saving irrigation technologies remains unclear, especially

amoA Gene Abundances and Nitrification Potential Rates Suggest that Benthic Ammonia-Oxidizing Bacteria and Not Archaea Dominate N Cycling in the Colne Estuary, United Kingdom [PDF]

, 2015
Nitrification, mediated by ammonia-oxidizing bacteria (AOB) and ammonia-oxidizing archaea (AOA), is important in global nitrogen cycling. In estuaries where gradients of salinity and ammonia concentrations occur, there may be differential selections for ...

Reduced Tillage Intercropping With Thymus hyemalis Reshapes the Rare Soil Microbiome and Co‐Occurrence Networks in a Semi‐Arid Almond Orchard

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Environmentally friendly farming practices are gaining interest, and intercropping is a promising option to protect soil health, yet its effects on orchard microbiomes and functions remain underexplored. In this study, we assessed a 3‐year intercropping assay of Capparis spinosa (D1) and Thymus hyemalis (D2) with almond and reduced tillage in ...
