This dataset supports the paper: "Environmental controls of dark CO2 fixation in wetland microbiota".

It contains genecluster abundances, annotations, taxonomy and membership for the metagenomic and metatranscriptomic analyses aswell as ASV tables for the 16S rRNA gene analyses.

This study was funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) within the Research Training Group2530: "Biota-mediated effects on Carbon cycling in Estuaries" (project number 407270017; contribution to Universität Hamburg and Leibniz-Institut für Gewässerökologie und Binnenfischerei im Forschungsverbund Berlin e.V.). This work was supported by the DFG Research Infrastructure NGS_CC (project 407495230) as part of the Next Generation Sequencing Competence Network (project 423957469) and core funding from ETH Zürich to the Microbiome Research Laboratory headed by S.S. Transcriptome and 16S rRNA sequencing were carried out at the Competence Centre for Genomic Analysis (Kiel). Peter Mueller was supported by the Deutsche Forschungsgemeinschaft (DFG; German Research Foundation) in the framework of the Emmy Noether Program (502681570).
