Genome, genetic evolution, and environmental adaptation mechanisms of Schizophyllum commune in deep subseafloor coal-bearing sediments [PDF]

iScience, 2022
Summary: To understand the genomic evolution and adaptation strategies of fungi to subseafloor sedimentary environments, we de novo assembled the genome of Schizophyllum commune strain 20R-7-F01 isolated from ∼2.0 km-deep, ∼20-millionyearsago (Mya) coal ...

Animal life in the shallow subseafloor crust at deep-sea hydrothermal vents [PDF]

Nature Communications
It was once believed that only microbes and viruses inhabited the subseafloor crust beneath hydrothermal vents. Yet, on the seafloor, animals like the giant tubeworm Riftia pachyptila thrive.

Metabolic and population profiles of active subseafloor autotrophs in young oceanic crust at deep-sea hydrothermal vents [PDF]

Applied and Environmental Microbiology
At deep-sea hydrothermal vents, magmatically driven rock-water reactions in the crust generate gases and other reduced compounds that subseafloor microorganisms use for chemolithoautotrophy.

The majority of microorganisms in gas hydrate-bearing subseafloor sediments ferment macromolecules [PDF]

Microbiome, 2023
Background Gas hydrate-bearing subseafloor sediments harbor a large number of microorganisms. Within these sediments, organic matter and upward-migrating methane are important carbon and energy sources fueling a light-independent biosphere.

Electrical resistivity tomography combined with seismic data estimates heterogeneous distribution of near-seafloor concentrated gas hydrates within gas chimneys [PDF]

Scientific Reports
Near-seafloor concentrated gas hydrates (GHs) containing large amounts of methane have been identified at various gas chimney sites. Although understanding the spatial distribution of GHs is fundamental for assessing their dissociation impact on ...

Evidence for the Existence of Mating Subtypes Within the Schizophyllum commune: Mating Behavior and Genetic Divergence [PDF]

Journal of Fungi
Schizophyllum commune, a Basidiomycota fungus with a tetrapolar mating system, serves as a key model for studying sexual reproduction. In this study, two distinct mating subtypes (I and II) were identified in strain 20R-7-ZF01, isolated from subseafloor ...

Cycling and persistence of iron-bound organic carbon in subseafloor sediments [PDF]

Nature Communications
Reactive iron (FeR) serves as an important sink of organic carbon (OC) in marine surface sediments, which preserves approximately 20% of total OC (TOC) as reactive iron-bound OC (FeR-OC).

Genome Evolution in Bacteria Isolated from Million-Year-Old Subseafloor Sediment

mBio, 2021
Beneath the seafloor, microbial life subsists in isolation from the surface world under persistent energy limitation. The nature and extent of genomic evolution in subseafloor microbes have been unknown.

Microbial Populations Are Shaped by Dispersal and Recombination in a Low Biomass Subseafloor Habitat

mBio, 2022
The subseafloor is a vast habitat that supports microorganisms that have a global scale impact on geochemical cycles. Many of the endemic microbial communities inhabiting the subseafloor consist of small populations under growth-limited conditions.
