Marker gene
We are using samples from this study:
Pascoal, F., Duarte, P., Assmy, P. & Costa, R. (2024) Full-length 16S rRNA gene sequencing combined with adequate database selection improves the description of Arctic marine prokaryotic communities. Annals of Microbiology.
This study contains both full-length (PacBio) and V4-V5 region (Illumina) 16S rRNA gene sequencing data for samples collected from the Arctic Ocean.
