Article Synopsis
- Arsenic compounds are accumulating in the deep ocean, with significant research conducted on sediment cores from the South China Sea and Mariana Trench highlighting their ecological impact.
- The study found that arsenite methylation is the main process for arsenic transformation in deep-sea sediments, with greater gene presence correlating to increased depth.
- New insights reveal distinct microbial strategies for arsenic detoxification, including the contribution of arsenite-oxidizing bacteria to the carbon cycle, expanding our understanding of deep-sea ecology.
Article Synopsis
- Rising consumer demand for sea cucumbers is damaging wild populations and marine ecosystems, highlighting the need for aquaculture as a sustainable alternative.
- This study analyzed the genetic and metabolic differences between fast-growing and slow-growing sea cucumbers, identifying over 2,000 differentially expressed genes related to fat digestion and various metabolic processes.
- Findings indicate that fast-growing sea cucumbers exhibit enhanced lipid metabolism and protein synthesis, along with increased apoptosis, which may help them better withstand environmental stresses, offering insights for improving aquaculture practices.
Heavy-metal pollution has increasingly jeopardized the habitats of marine organisms including the sea cucumber, a seafloor scavenger vital to seawater bio-decontamination, ocean de-acidification and coral-reef protection. Normal physiology including immune functions of sea cucumbers is toxicologically modulated by marine metal pollutants such as cadmium (Cd). The processes underpinning Cd's toxic effects on immune systems in the sea cucumber, , are still poorly understood.

In this study, the complete mitochondrial genome (mitogenome) of was acquired through high-throughput sequencing. The mitochondrial genome of was 15,656 bp in total length and contained a putative control region (CR) and 37 typical genes of animal mitochondrial genomes, including 13 protein-coding genes (PCGs), 2 ribosomal RNA genes ( and ) and 22 transfer RNA genes (tRNA).

In this study, the complete mitochondrial genome (mitogenome) of was sequenced. The mitogenome was 16,239 bp in length and contained 13 protein-coding genes (PCGs), 22 transfer RNA genes (tRNAs), and 2 ribosomal RNA genes (rRNAs).

The limited phage resources and poor genomic data hinder the understanding of the lysis mechanism of Enterobacter cloacae phages. In the present study, we characterized a newly discovered lytic phage PZJ0206 that infects an E.

In this study, a series of phage-resistant mutant (PRM) strains derived from were isolated and Infrequent-restriction-site PCR (IRS-PCR) was used to investigate the genetic diversity of the PRM strains. Phenotypic variations of eight PRM strains were analyzed using profiles of utilizing carbon sources and chemical sensitivity.
