Neighbour joining consensus tree of archaeal amoA phylotypes.

, 2014
Colored branches indicate the Nitrosotalea cluster (green) and Nitrososphaera cluster (blue). Boot strap values are indicated at nodes. Cluster designations follow the classification of Pester et al. [25] based on nucleic acid alignment of archaeal amoA.

Genetic and transcriptional profiles of ammonia oxidizing communities in Bohai sediments: abundance, activity, and environmental correlations

Frontiers in Microbiology
Ammonia oxidation, a crucial part in nitrogen cycle, is thought to be jointly driven by ammonia-oxidizing archaea (AOA), ammonia-oxidizing bacteria (AOB), and complete ammonia oxidation (comammox) in the ocean.

Direct Detection by In Situ PCR of the amoA Gene in Biofilm Resulting from a Nitrogen Removal Process

, 2001
Ammonia oxidation is a rate-limiting step in the biological removal of nitrogen from wastewater. Analysis of microbial communities possessing the amoA gene, which is a small subunit of the gene encoding ammonia monooxygenase, is ...

Distributions of crenarchaeal amoA genes and transcripts in the Pacific Ocean

, 2010
Planktonic Crenarchaea are thought to play a key role in chemolithotrophic ammonia oxidation, a critical step of the marine nitrogen (N) cycle. In this study, we examined the spatial distributions of ammonia-oxidizing Crenarchaea across a large (∼5200 km) region of the central Pacific Ocean.

Gene-Level Shift in Response to Synthetic Nitrogen Addition Promotes Larix olgensis (Ussurian Larch) Growth in a Short-Term Field Trial

Life
Climate change and injudicious nitrogen addition alter the soil physico-chemical properties and microbial activity in oligotrophic forest soil, which disrupts the nitrogen cycle balance.

Identification of major subgroups of ammonia-oxidizing bacteria in environmental samples by T-RFLP analysis of amoA PCR products

, 2000
A cloning-independent method based on T-RFLP (terminal restriction fragment length polymorphism) analysis of amoA PCR products was developed to identify major subgroups of autotrophic ammonia oxidizers of the beta-subclass of the class Proteobacteria in ...

Global occurrence and biogeography of putative archaeal amoA genes in terrestrial hot springs

, 2008
Despite the ubiquity of ammonium in geothermal environments and the thermodynamic favorability of aerobic ammonia oxidation, thermophilic ammonia-oxidizing microorganisms belonging to the crenarchaeota kingdom have only recently been described.
