Metagenomic and Metatranscriptomic Profiling of Coastal Wetland Sediments

Key Points

To analyze microbial communities in coastal wetland sediments using metagenomic and metatranscriptomic techniques.
Collected sediment samples across diverse coastal ecosystems in China.
Integrated DNA-based metabolic potential and RNA-based transcriptional data.
Studied variations in microbial community structure and responses to environmental factors.
Identified key microbial mechanisms involved in carbon, nitrogen, and sulfur cycling.
Revealed how microbial communities respond to environmental gradients and human activities.

Abstract

This study presents a comprehensive multi-omics dataset (metagenomics and metatranscriptomics) derived from coastal wetland sediments across the entire coastline of China. Samples were collected from diverse coastal ecosystems, spanning a broad latitudinal range to capture variations in microbial community structure and functional potential. By integrating DNA-based metabolic potential with RNA-based transcriptional activity, this dataset aims to elucidate the microbial mechanisms driving biogeochemical cycling (e.g., carbon, nitrogen, and sulfur) and their responses to environmental gradients and anthropogenic pressures in salt marshes and mangroves.
