Family‐level specialization in protein domain insertion architectures

Protein Science, Volume 35, Issue 5, May 2026.
Abstract Domain insertion creates architectures where one domain interrupts another's sequence. Analysis across 2.7 million classified domains reveals that insertions occur in 20% of multidomain proteins, with 331 families exhibiting consistent architectural roles: 162 function exclusively as hosts, while 169 exclusively serve as inserted modules, such

The diversity of a distributed genome in bacterial populations

, 2010
The distributed genome hypothesis states that the set of genes in a population of bacteria is distributed over all individuals that belong to the specific taxon. It implies that certain genes can be gained and lost from generation to generation.

Picophytoplankton biomass distribution in the global ocean [PDF]

, 2012
The smallest marine phytoplankton, collectively termed picophytoplankton, have been routinely enumerated by flow cytometry since the late 1980s during cruises throughout most of the world ocean. We compiled a database of 40 946 data points, with separate

Physical and Ecological Forcings Drive the Particle Dynamics and Enhanced Carbon Export Efficiency in the Tropical Marginal Sea

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Marginal seas contribute disproportionately to the ocean carbon cycle but remain poorly constrained due to strong spatial and seasonal variability. Here, we combine newly collected in situ particle imagery with machine learning to reconstruct monthly, depth‐resolved climatologies of particle biovolume and size distribution in the South China ...

Gene Order Phylogeny of the Genus Prochlorococcus

PLoS ONE, 2008
Using gene order as a phylogenetic character has the potential to resolve previously unresolved species relationships. This character was used to resolve the evolutionary history within the genus Prochlorococcus, a group of marine cyanobacteria.Orthologous gene sets and their genomic positions were identified from 12 species of Prochlorococcus and 1 ...

Bacteria as Passive Passengers in the Equatorial Pacific Biological Carbon Pump

Geophysical Research Letters, Volume 53, Issue 8, 28 April 2026.
Abstract Bacteria are important agents modulating the efficiency of the ocean's biological carbon pump (BCP). The long‐standing view considers bacteria as degraders of sinking particulate organic carbon (POC), yet underappreciates their contribution to carbon export.

Dynamic cycling and redox transformations of dissolved organic sulfur in the surface ocean

Limnology and Oceanography, Volume 71, Issue 4, April 2026.
Abstract The marine dissolved organic sulfur (DOS) pool contains both labile metabolites that are rapidly cycled in the surface ocean and compounds that may persist for thousands of years in the marine environment. Here, we describe the sulfur speciation of marine solid‐phase extracted DOS (DOSSPE) from the North Atlantic surface ocean, revealing a ...

Species-level functional profiling of metagenomes and metatranscriptomes. [PDF]

, 2018
Functional profiles of microbial communities are typically generated using comprehensive metagenomic or metatranscriptomic sequence read searches, which are time-consuming, prone to spurious mapping, and often limited to community-level quantification ...

Prochlorococcus Cells Rely on Microbial Interactions Rather than on Chlorotic Resting Stages To Survive Long-Term Nutrient Starvation

mBio, 2020
The ability of microorganisms to withstand long periods of nutrient starvation is key to their survival and success under highly fluctuating conditions that are common in nature.
