Archaeal and bacterial 16S rRNA transcript amplicon sequences recovered from Amazonian floodplains with different water types

Soils from wetland areas contribute significantly to the global methane (CH4) budget. In this sense, this work was designed to evaluate the influence of dry and flooding in the active microbial communities involved in the production and consumption of CH4 in wetland areas under forest and traditional farming system in Amazonian black, white and clear floodplains. Molecular RNA- and 16S ribosomal RNA gene-based analyzes, and soil physicochemical analyzes were performed to reveal the soil methanogenic and methanotrophic microbial communities and investigate the relationships between these microbial communities and the physcochemical factors of soil from forest sites and traditional farming systems in two different soil layers (0-15 cm and 15-30 cm) and in two seasonal periods (non-flooded and flooded period).
