High-Throughput Reconstruction of 8,236 Microbial Genomes from Guangdong Mangrove Sediments
Mangrove habitats, characterized by high salinity, dynamic redox potential, carbon abundance, nitrogen limitation, sulfur richness, and anaerobic conditions, harbor abundant and unique microbial assemblages that drive key global biogeochemical cycles. Here, to uncover the microbial community structure and their potential functions, we collected a total of 56 sediment samples, including both surface (0–5 cm, 16 samples) and subsurface core (up to 90 cm, 40 samples) layers, from eight representative mangrove sites from Zhanjiang mangrove reserve, China. Applying a standardized pipeline for assembly, binning, and dereplication, we reconstructed 8,235 non-redundant metagenome-assembled genomes (MAGs), consisting of 6,604 bacterial and 1,631 archaeal genomes spanning 66 bacterial and 13 archaeal phyla, respectively. This data collection encompasses the extensive microbial diversity and metabolic potential present in mangrove sediments across fluctuating environmental regimes. It serves as an indispensable genomic resource for elucidating the composition, metabolic pathways, and ecological contributions of sediment microbiomes in nutrient-rich intertidal ecosystems, facilitating subsequent investigations into microbial adaptation and biogeochemical processes within global blue carbon systems.
