Revitalized abyssal ancient viruses trigger viral pandemic in terrestrial soil.

Viruses are the most abundant biological entities on the earth. Some ancient viruses can revive from permafrost along with melting to infect the current hosts. The "zombie viruses" trapped in the ancient deep-sea sediments become the public health concern due to the environmental changes and human activities in deep oceans.

Interactions between the nitrogen-fixing cyanobacterium and siderophore-producing cyanobacterium under iron limitation.

As diazotrophic cyanobacteria of tremendous biomass, continuously provide a nitrogen source for carbon-fixing cyanobacteria and drive the generation of primary productivity in marine environments. However, ocean iron deficiencies limit growth and metabolism of . Recent studies have shown the co-occurrence of and siderophore-producing in iron-deficient oceans, but whether siderophores secreted by can be used by to adapt to iron deficiency is not clear.

Diversities and interactions of phages and bacteria in deep-sea sediments as revealed by metagenomics.

Phages are found virtually everywhere, even in extreme environments, and are extremely diverse both in their virion structures and in their genomic content. They are thought to shape the taxonomic and functional composition of microbial communities as well as their stability. A number of studies on laboratory culture and viral metagenomic research provide deeper insights into the abundance, diversity, distribution, and interaction with hosts of phages across a wide range of ecosystems.

A dataset of micro biodiversity in benthic sediment at a global scale.

Microorganisms, occupying the largest biomass in deep sea, play essential roles in deep-sea ecosystem. It is believed that the microbes in deep-sea sediments are more representative of deep-sea microbial communities, the microbial composition of which is seldom affected by ocean currents. However, the community of benthic microbes on a global scale has not been adequately explored.

Environmental viromes reveal the global distribution signatures of deep-sea DNA viruses.

Introduction: Viruses are abundant and ecologically significant in marine ecosystems. However, the virome of deep-sea sediments is not extensively investigated.

Objectives: To explore the distribution pattern of deep-sea viruses on a global scale, the viromes of DNA viruses isolated from 138 sediments of 5 deep-sea ecosystems were characterized.

Exosomes from WSSV-infected shrimp contain viral components that mediate virus infection.

Exosomes have been described as vesicles that mediate intercellular communication and thus affect normal and pathological processes. Furthermore, many viruses have been reported to deliver viral components to host cells through exosomes. However, the roles of exosomes in invertebrates response to virus infection are poorly understood.

Core Gut Microbiota of Shrimp Function as a Regulator to Maintain Immune Homeostasis in Response to WSSV Infection.

The gut microbiota is an integral part of the host and has a functional potential in host physiology. Numerous scientific efforts have opened new horizons in gut microbiota research and enhanced the understanding of host-microbe interactions in vertebrates. However, evidence on the association between the gut microbiota and immunity in invertebrates, especially in shrimp, which is an important aquatic animal, is limited.

Artificial construction of the biocoenosis of deep-sea ecosystem via seeping methane.

Deep-sea ecosystems, such as cold seeps and hydrothermal vents, have high biomass, even though they are located in the benthic zone, where no sunlight is present to provide energy for organism proliferation. Based on the coexistence of the reduced gases and chemoautotrophic microbes, it is inferred that the energy from the reduced gases supports the biocoenosis of deep-sea ecosystems. However, there is no direct evidence to support this deduction.

A Novel Benzoquinone Compound Isolated from Deep-Sea Hydrothermal Vent Triggers Apoptosis of Tumor Cells.

Microorganisms are important sources for screening bioactive natural products. However, natural products from deep-sea microbes have not been extensively explored. In this study, the metabolites of bacteriophage GVE2 -infected ( sp.
