Synthesis of publicly-available sequence datasets of the 16S rRNA gene in environmental DNA extracted from seafloor and subseafloor samples from the Dorado outcrop, Lō'ihi Seamount, North Pond, and Juan de Fuca Ridge flank

Abstract

To summarize crustal bacterial and archaeal taxa for this review, we synthesized publicly-available sequence datasets of the 16S rRNA gene in environmental DNA extracted from seafloor and subseafloor basalts generated using 454, Illumina and Ion Torrent amplicon platforms. These include seafloor basalts from the Dorado Outcrop and the Lō'ihi Seamount in the Pacific Ocean and subseafloor basalts from North Pond on the western flank of the Mid-Atlantic Ridge and the Juan de Fuca Ridge flank in the northeastern Pacific Ocean. Datasets from rock colonization experiments conducted in the subseafloor at the Juan de Fuca Ridge flank site were also included, as well as microbial community surveys of the subseafloor crustal fluids from the anoxic Juan de Fuca site and the oxic North Pond site.
