Journal ArticleDOI
Heterotrophic Archaea dominate sedimentary subsurface ecosystems off Peru
Jennifer F. Biddle,Julius S. Lipp,Mark A. Lever,Karen G. Lloyd,Ketil Bernt Sørensen,Rika E. Anderson,Rika E. Anderson,Helen F. Fredricks,Marcus Elvert,Timothy J. Kelly,Daniel P. Schrag,Mitchell L. Sogin,Jean E. Brenchley,Andreas P Teske,Christopher H. House,Kai-Uwe Hinrichs,Kai-Uwe Hinrichs +16 more
TL;DR: It is shown that extractable archaeal rRNA, selecting only for active community members in these ecosystems, is dominated by sequences of uncultivated Archaea affiliated with the Marine Benthic Group B and the Miscellaneous Crenarchaeotal Group, whereas known methanotrophic Archaea are not detectable.
Journal ArticleDOI
Metagenomic signatures of the Peru Margin subseafloor biosphere show a genetically distinct environment.
Jennifer F. Biddle,Sorel Fitz-Gibbon,Stephan C. Schuster,Jean E. Brenchley,Christopher H. House +4 more
TL;DR: The findings show that the marine subsurface is a distinct microbial habitat and is different from environments studied by metagenomics, especially because of the predominance of uncultivated archaeal groups.
Journal ArticleDOI
Archaea of the Miscellaneous Crenarchaeotal Group are abundant, diverse and widespread in marine sediments
Kyoko Kubo,Karen G. Lloyd,Karen G. Lloyd,Karen G. Lloyd,Jennifer F. Biddle,Jennifer F. Biddle,Rudolf Amann,Andreas P Teske,Katrin Knittel +8 more
TL;DR: Members of the highly diverse Miscellaneous Crenarchaeotal Group (MCG) are globally distributed in various marine and continental habitats and their high diversity and widespread distribution in subsurface sediments indicates that this group is globally important in sedimentary processes.
Journal ArticleDOI
Gene expression in the deep biosphere
TL;DR: The first sub-seafloor metatranscriptomes from anaerobic Peru Margin sediment up to 159 metres below the sea floor are described and analysed, representing the first holistic picture of deep biosphere activities.
Journal ArticleDOI
Global dispersion and local diversification of the methane seep microbiome
TL;DR: The results indicate that the seep microbiome is structured according to metacommunity processes and that few cosmopolitan microbial taxa mediate the bulk of methane oxidation, with global relevance to methane emission in the ocean.
