Genomic Characteristics and Potential Metabolic Adaptations of Hadal Trench Roseobacter and Alteromonas Bacteria Based on Single-Cell Genomics Analyses

Frontiers in Microbiology, 2020
Heterotrophic bacteria such as those from the Roseobacter group and genus Alteromonas dominate the hadal zones of oceans; however, we know little about the genomic characteristics and potential metabolic adaptations of hadal trench-dwelling bacteria ...

A novel active deep-sea low-damage pressure-retaining organisms sampler

Frontiers in Marine Science, 2022
Capturing less damaged organisms samples is the basis for research on the biological communities, living environments, biological life compositions, and biological tissue structures of organisms livinin the deep seabed.

Revealing the full biosphere structure and versatile metabolic functions in the deepest ocean sediment of the Challenger Deep

Genome Biology, 2021
Background The full biosphere structure and functional exploration of the microbial communities of the Challenger Deep of the Mariana Trench, the deepest known hadal zone on Earth, lag far behind that of other marine realms.

Hadal Biodiversity, Habitats and Potential Chemosynthesis in the Java Trench, Eastern Indian Ocean

Frontiers in Marine Science, 2022
The Java Trench is the only subduction trench in the Indian Ocean that extends to the hadal zone (> 6,000 m water depth), and except for sevenbenthic trawls acquired around the 1950s, there has been little to no sampling at hadal depths undertaken ...

Megafaunal Community Structure From the Abyssal to Hadal Zone in the Yap Trench

Frontiers in Marine Science, 2021
Hadal trenches remain one of the unexplored ocean ecosystems due to the challenges of sampling at great depths. It is still unclear how a faunal community changes from the abyssal to the hadal zone, and which environmental variables are the key impacting

Anammox bacteria drive fixed nitrogen loss in hadal trench sediments [PDF]

Proceedings of the National Academy of Sciences, 2021
SignificanceHadal trenches represent the deepest part of the oceans, apparently offering adverse conditions for life, given their high hydrostatic pressure and wide separation from the productive surface waters. However, focusing of reactive organic matter in trench axis sediments potentially promotes complex yet unexplored microbial communities and ...

The genome of a hadal sea cucumber reveals novel adaptive strategies to deep-sea environments

iScience, 2022
Summary: How organisms cope with coldness and high pressure in the hadal zone remains poorly understood. Here, we sequenced and assembled the genome of hadal sea cucumber Paelopatides sp.

Hadal Mud Dragons: First Insight Into the Diversity of Kinorhyncha From the Atacama Trench [PDF]

Frontiers in Marine Science, 2021
Deep-sea trenches are one of the last frontiers for deep-sea exploration and represent a large reservoir of undiscovered biodiversity. This applies in particular to organisms belonging to smaller-size classes, such as meiofauna. Among different meiofauna taxa, kinorhynchs represent a large gap in our knowledge about global marine biodiversity in ...
