Dataset for: Nematode‐associated microbial taxa do not correlate with host phylogeny, geographic region or feeding morphology in marine sediment habitats

Marine nematode microbiomes were studied by isolating host-associated microbial taxa in nematodes from the Gulf of Mexico. A two‐gene metabarcoding approach was used to amplify the V4 region of the 16S ribosomal RNA (rRNA) gene targeting bacteria/archaea and the V1–V2 region of the 18S rRNA gene targeting microbial eukaryotes. This dataset contains nematode taxonomic identifications, video images, and 18S rRNA, 16S rRNA, NGS reads (fastq) from samples collected in the Gulf of Mexico in June and July of 2007.
