Role of methanotrophic communities in atmospheric methane oxidation in paddy soils.

ABSTRACT: Wetland systems are known methane (CH₄) sources. However, flooded rice fields are periodically drained. The paddy soils can absorb atmospheric CH₄ during the dry seasons due to high-affinity methane-oxidizing bacteria (methanotroph). Atmospheric CH₄ uptake can be induced during the low-affinity oxidation of high-concentration CH₄ in paddy soils. Multiple interacting factors control atmospheric CH₄ uptake in soil ecosystems. Broader biogeographical data are required to refine our understanding of the biotic and abiotic factors related to atmospheric CH₄ uptake in paddy soils. Thus, here, we aimed to assess the high-affinity CH₄ oxidation activity and explored the community composition of active atmospheric methanot
