Microbiome‐mediated plant‐soil feedbacks as a tool for resilient agriculture

iMetaOmics, Volume 3, Issue 3, September 2026.
Translating plant‐soil feedbacks (PSFs) into reliable agricultural management requires shifting from input‐dependent practices toward endogenous, process‐driven crop resilience. To bridge this gap, we propose a predictive framework centered on three strategic interventions: engineering the crop holobiont, diversifying the soil habitat, and deploying ...

Cloning, mutagenesis, and nucleotide sequence of a siderophore biosynthetic gene (amoA) from Aeromonas hydrophila [PDF]

Journal of Bacteriology, 1991
Many isolates of the Aeromonas species produce amonabactin, a phenolate siderophore containing 2,3-dihydroxybenzoic acid (2,3-DHB). An amonabactin biosynthetic gene (amoA) was identified (in a Sau3A1 gene library of Aeromonas hydrophila 495A2 chromosomal DNA) by its complementation of the requirement of Escherichia coli SAB11 for exogenous 2,3-DHB to ...

Differential Responses of Nitrifier and Denitrifier to Dicyandiamide in Short- and Long-Term Intensive Vegetable Cultivation Soils

Journal of Integrative Agriculture, 2014
Nitrification inhibitors, such as dicyandiamide (DCD), have been shown to decrease leaching from urea- and ammonium-based fertilizers in agricultural soils.

Warm‐wet transition restructures arid lake microbiomes and functional potential

iMetaOmics, Volume 3, Issue 3, September 2026.
This study summarizes how a long‐term warm‐dry to warm‐wet transition restructures microbiomes and functional potential in Lake Bosten, an arid lake in northwestern China. Warm‐wet hydroclimatic change increased water level and hydrological connectivity, while decreasing salinity and total nitrogen.

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.

Iron/Manganese Oxide‐Bound Nitrogen Suppresses Microbial Mediated Nitrate Reduction in Soil

Land Degradation &Development, Volume 37, Issue 15, Page 10784-10794, September 2026.
ABSTRACT Nitrogen cycling plays a pivotal role in sustaining ecosystem productivity and stability, while the chemical forms of nitrogen in soils critically influence both its efficiency and pathways. In this study, farmland soils from the Anning River Basin—an important watershed in Southwest China—were investigated to examine the regulatory effects of

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 ...

Sedimentary lycopane/n‐C31 ratio as a proxy for bottom water hypoxia in coastal ocean

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Bottom‐water hypoxia on continental shelves is intensifying under climate change and eutrophication, yet long‐term records remain scarce. Here we show that the sedimentary lycopane/n‐C31 ratio reliably records bottom‐water oxygenation in the seasonally hypoxic Yangtze River Estuary.
