Fungal iTAG analyses on Peru Margin sediment core samples Dataset Description: Methods and Sampling: <p>Peru Margin subsurface sediments were sampled on&nbsp;IODP leg 201 site 1229A (10°58.5721’ S 77°57.4590’W) in&nbsp;150.5 m water depth. Core depth at 1229A was 187 mbsf.</p>
<p>DNA was extracted from either 2 or 20 grams of exterior and interior core sediment from frozen&nbsp;(stored at -80 degree&nbsp;C) Peru Margin samples collected at 6 mbsf (2H2) and 95 mbsf (11H5), respectively,&nbsp;using the PowerSoil DNA Isolation Kit (MoBio Laboratories, USA). Extractions were also performed&nbsp;for replicate samples collected from the exterior of both cores. The manufacturer’s protocol was&nbsp;modified to include five repetitions of homogenization for 1-minute intervals, with 1 minute rest in&nbsp;between, using a FastPrep benchtop homogenizer (MP Biomedicals, Santa Ana, CA) set to 4.0 m/s. A final purification step using isopropanol precipitation was also added. Duplicate extractions were&nbsp;performed for both interior and exterior regions of each core.&nbsp;Partial small-subunit ribosomal DNA (SSU rDNA) fragments were PCR amplified from&nbsp;DNA extracts using the key-tagged fungal-targeting primer set nu-SSU-0817-5’ and nu-SSU-1196-3’ (Borneman and Hartin, 2000). Replicate PCR amplifications (3-6) were run&nbsp;for each sample using Phusion High-Fidelity DNA Polymerase (ThermoFisher Scientific,&nbsp;USA) and 5X Phusion HF Buffer. PCR conditions were: 98 degrees&nbsp;C for 30 seconds followed&nbsp;by 40 cycles of 98 degrees&nbsp;C for 10 seconds, 56 degrees&nbsp;C for 30 seconds, and 72 degrees&nbsp;C for 30 seconds, and&nbsp;a final incubation for 7 minutes at 72 degrees&nbsp;C. PCR products were visualized by agarose gel electrophoresis and positive results were excised and purified from the gel using the&nbsp;ZymoClean Gel DNA recovery Kit (Zymo Research, USA). Purified replicate PCR&nbsp;amplifications from each sample were combined prior to iTAG sequencing using Illumina&nbsp;MiSeq PE300 at Georgia Genomics Center.</p>

Center for Dark Energy Biosphere Investigations
The mission of the Center for Dark Energy Biosphere Investigations (C-DEBI) is to explore life beneath the seafloor and make transformative discoveries that advance science, benefit society, and inspire people of all ages and origins.
C-DEBI provides a framework for a large, multi-disciplinary group of scientists to pursue fundamental questions about life deep in the sub-surface environment of Earth. The fundamental science questions of C-DEBI involve exploration and discovery, uncovering the processes that constrain the sub-surface biosphere below the oceans, and implications to the Earth system. What type of life exists in this deep biosphere, how much, and how is it distributed and dispersed? What are the physical-chemical conditions that promote or limit life? What are the important oxidation-reduction processes and are they unique or important to humankind? How does this biosphere influence global energy and material cycles, particularly the carbon cycle? Finally, can we discern how such life evolved in geological settings beneath the ocean floor, and how this might relate to ideas about the origin of life on our planet?
C-DEBI's scientific goals are pursued with a combination of approaches:
(1) coordinate, integrate, support, and extend the research associated with four major programs—Juan de Fuca Ridge flank (JdF), South Pacific Gyre (SPG), North Pond (NP), and Dorado Outcrop (DO)—and other field sites;
(2) make substantial investments of resources to support field, laboratory, analytical, and modeling studies of the deep subseafloor ecosystems;
(3) facilitate and encourage synthesis and thematic understanding of submarine microbiological processes, through funding of scientific and technical activities, coordination and hosting of meetings and workshops, and support of (mostly junior) researchers and graduate students; and
(4) entrain, educate, inspire, and mentor an interdisciplinary community of researchers and educators, with an emphasis on undergraduate and graduate students and early-career scientists.
Note: Katrina Edwards was a former PI of C-DEBI; James Cowen is a former co-PI.
Data Management:
C-DEBI is committed to ensuring all the data generated are publically available and deposited in a data repository for long-term storage as stated in their Data Management Plan (PDF) and in compliance with the NSF Ocean Sciences Sample and Data Policy. The data types and products resulting from C-DEBI-supported research include a wide variety of geophysical, geological, geochemical, and biological information, in addition to education and outreach materials, technical documents, and samples. All data and information generated by C-DEBI-supported research projects are required to be made publically available either following publication of research results or within two (2) years of data generation.
To ensure preservation and dissemination of the diverse data-types generated, C-DEBI researchers are working with BCO-DMO Data Managers make data publicly available online. The partnership with BCO-DMO helps ensure that the C-DEBI data are discoverable and available for reuse. Some C-DEBI data is better served by specialized repositories (NCBI's GenBank for sequence data, for example) and, in those cases, BCO-DMO provides dataset documentation (metadata) that includes links to those external repositories.

Exploring of the Ecological Role(s) of Marine Fungi in the Deep Subseafloor

Exploring of the Ecological Role(s) of Marine Fungi in the Deep Subseafloor
<p>The deep sedimentary biosphere, extending hundreds of meters below the seafloor harbors unexpected diversity of Bacteria, Archaea and microbial eukaryotes. Far less is known about microbial eukaryotes in subsurface habitats, albeit several studies have indicated that fungi dominate microbial eukaryotic communities and fungal molecular signatures (of both yeasts and filamentous forms) have been detected in samples as deep as 1740mbsf. Here we compare and contrast fungal ribosomal RNA gene signatures and whole community metatranscriptomes present in sediment core samples from 6 and 95mbsf from Peru Margin site 1229A and from samples from 12 and 345 mbsf from Canterbury Basin site U1352. The metatranscriptome analyses reveal higher relative expression of amino acid and peptide transporters in the less nutrient rich Canterbury Basin sediments compared to the nutrient rich Peru Margin, and higher expression of motility genes in the Peru Margin samples. Higher expression of genes associated with metals transporters and antibiotic resistance and production was detected in Canterbury Basin sediments. A poly-A focused metatranscriptome produced for the Canterbury Basin sample from 345 mbsf provides further evidence for active fungal communities in the subsurface in the form of fungal-associated transcripts for metabolic and cellular processes, cell and membrane functions, and catalytic activities. Fungal communities at comparable depths at the two geographically separated locations appear dominated by distinct taxa. Differences in taxonomic composition and expression of genes associated with particular metabolic activities may be a function of sediment organic content as well as oceanic province. Microscopic analysis of Canterbury Basin sediment samples from 4 and 403 mbsf produced visualizations of septate fungal filaments, branching fungi, conidiogenesis and spores. These images provide another important line of evidence supporting the occurrence and activity of fungi in the deep subseafloor biosphere.</p>

More information is available from IODP (PDF).
PI Supplied Instrument Name: PI Supplied Instrument Description:Purified replicate PCR amplifications from each sample were combined prior to iTAG sequencing using Illumina MiSeq PE300 at Georgia Genomics Center. Instrument Name: Automated DNA Sequencer Instrument Short Name:Automated Sequencer Instrument Description: A DNA sequencer is an instrument that determines the order of deoxynucleotides in deoxyribonucleic acid sequences.
PI Supplied Instrument Name: Instrument Name: Thermal Cycler Instrument Short Name:Thermal Cycler Instrument Description: A thermal cycler or "thermocycler" is a general term for a type of laboratory apparatus, commonly used for performing polymerase chain reaction (PCR), that is capable of repeatedly altering and maintaining specific temperatures for defined periods of time. The device has a thermal block with holes where tubes with the PCR reaction mixtures can be inserted. The cycler then raises and lowers the temperature of the block in discrete, pre-programmed steps. They can also be used to facilitate other temperature-sensitive reactions, including restriction enzyme digestion or rapid diagnostics.
