Assembled genomes of sulfur-oxidizing symbiotic bacteria in the gut of polychaetes

The data were further processed with FastUniq to remove duplicated reads. Clean data were separately assembled using both SPAdes with the recommended settings for metagenomes and MEGAHIT with default settings. Assembled datasets were subjected to MetaWRAP v1.2.1 for genome binning with default settings.

These retrieved MAGs were then de-replicated together using dRep, which resulted in 12 Sulfurovaceae MAGs.The final released dataset comprises 12 MAGs of sulfur-oxidizing symbionts, all with completeness higher than 50% and contamination lower than 10%.The nucleotide sequences of each MAG are provided in separate standard FASTA format files (.fna). Corresponding predicted protein-coding sequence files (.faa) and functional annotation files (.gff) are also provided.

All relevant files (including the core data table and individual genome sequence and annotation files) have been consolidated and compressed into an archive named "Polychaetes_symbiont_MAGs_dataset.zip". These data provide a valuable genomic resource for in-depth studies of host-microbe interaction mechanisms in deep-sea chemosynthetic ecosystems.
