TL;DR: The induction of HAMO activity occurred only after the rapid growth of methanotrophic populations, and a metatranscriptome-wide association study suggests that the concurrent high- and low-affinity methane oxidation was catalysed by known meethanotrophs rather than by the proposed novel atmospheric methane oxidizers.

TL;DR: Using DNA-based stable isotope probing and pyrosequencing of 16S rRNA and functional genes, this paper reported on biogeochemical and molecular evidence for growth stimulation of methanotrophic communities by ammonium fertilization, and that methane modulates nitrogen cycling by competitive inhibition of nitrifying communities in a rice paddy soil.

TL;DR: The results provide strong evidence for the adaptive growth of Nitrososphaera-like AOA in acidic soil, suggesting a greater metabolic versatility of soil AOA than previously appreciated.

TL;DR: The results of this study suggest that the marine group 1.1a-associated AOA will be better adapted to the flooded paddy field than AOA ecotypes of the soil group1.1b lineage, and indicate that long-term flooding is the dominant selective force driving the community diversification of AOA populations in the acid soil tested.

TL;DR: Real-time PCR analysis of methanotroph-specific biomarker pmoA genes of the buoyant density for DNA gradient, following the ultracentrifugation of the total DNA extracted from SIP microcosms, indicated an enrichment of methnotroph genomes in 13C-labeled DNA and suggested propagation of microbial methane oxidizers in soils.
