Global distribution and diversity of marine Parmales

This study analyzes the global distribution and diversity of Parmales using DNA metabarcoding data, revealing low abundance and diversity with clade-specific ecological adaptations.

Gene transfer among viruses substantially contributes to gene gain of giant viruses

The paper investigates viral horizontal gene transfer (vHGT) among nucleocytoviruses and finds it accounts for 28% to 42% of gene gain events in each viral order.

Characterization of sinking and suspended microeukaryotic communities in spring Oyashio waters

This study characterizes sinking and suspended microeukaryotic communities in Oyashio waters using 18S rDNA metabarcoding, revealing depth-related differences and functional roles in the biological carbon pump.

Genomic adaptation of giant viruses in polar oceans

This study investigates how giant viruses adapt to polar ocean environments by analyzing their biogeography and functional genes, finding that their adaptation is independent of host adaptation.

Global observation of plankton communities from space

The paper uses satellite data and machine learning to predict global plankton community distributions with 67% accuracy, outperforming temperature and chlorophyll a alone.

Genome analysis of Parmales, a sister group of diatoms, reveals the evolutionary specialization of diatoms from phago-mixotrophs to photoautotrophs

This study compares parmalean and diatom genomes to show diatoms evolved from phago-mixotrophs to photoautotrophs by losing phagocytosis genes and gaining silica and nutrient metabolism capabilities.

RNA-seq of the medusavirus suggests remodeling of the host nuclear environment at an early infection stage

This paper uses RNA-seq to analyze medusavirus infection in amoebas, identifying temporal gene expression clusters and host transcriptional changes, suggesting early nuclear remodeling by the virus.

Discovery of viral myosin genes with complex evolutionary history within plankton

The paper discovers myosin genes in NCLDVs, suggests their role in viral transport, and identifies multiple horizontal transfers of these genes between viruses and eukaryotes.

Etmopterus lantern sharks use coelenterazine as the substrate for their luciferin-luciferase bioluminescence system

This study identifies coelenterazine as the substrate for bioluminescence in lantern sharks, confirming its role in the luciferin-luciferase reaction in their ventral photophore tissues.

Ocean-wide comparisons of mesopelagic planktonic community structures

This study compares mesopelagic planktonic community structures across different oxygen conditions and identifies environmental drivers and community modules.

Year-round dynamics of amplicon sequence variant communities differ among eukaryotes, Mimiviridae, and prokaryotes in a coastal ecosystem

A one-year observation of coastal microbial communities revealed similar but different community dynamics for eukaryotes, a group of large viruses, and prokaryotes.

Quantitative assessment of NCLDV-host interactions predicted by co-occurrence analyses

This study uses co-occurrence analyses to predict NCLDV hosts from Tara Oceans data, showing improved performance with a phylogeny-informed method.

Eukaryotic virus composition can predict the efficiency of carbon export in the global ocean

This study links viral community composition to carbon export efficiency in the global ocean, finding that viral marker genes explain 67% of variation in CEE.

The two-step chemosensory system underlying the oligophagy of silkworm larvae

This study identifies a two-step chemosensory system in silkworm larvae that integrates plant chemical cues to determine host acceptance.
