Presence of toxin-antitoxin systems in picocyanobacteria and their ecological implications [PDF]
The ISME Journal, 2020 Abstract Picocyanobacteria (mainly Synechococcus and Prochlorococcus) contribute significantly to ocean’s primary production. Toxin-Antitoxin (TA) systems present in bacteria and archaea are known to regulate cell growth in response to environmental stresses. However, little is known about the presence of TA systems in picocyanobacteria.

Seasonal patterns and interannual variability of phytoplankton in Lake Stechlin [PDF]
, 2004 The paper presents results of detailed phytoplankton investigations in Lake Stechlin between 1994 and 2003. The analysis includes the picoplankton fraction (dominated by Cyanobium sp.) that regularly appears as a deep-layer chlorophyll maximum (DCM ...

Metabolic evolution and the self-organization of ecosystems [PDF]
, 2017 Metabolism mediates the flow of matter and energy through the biosphere. We examined how metabolic evolution shapes ecosystems by reconstructing it in the globally abundant oceanic phytoplankter Prochlorococcus To understand what drove observed ...

Frontiers in Microbiology, 2022 Isolates of the marine picocyanobacteria, Prochlorococcus and Synechococcus, are often accompanied by diverse heterotrophic “contaminating” bacteria, which can act as confounding variables in otherwise controlled experiments.

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.Two model strains of Synechococcus sp.—the marine RS9907 and the euryhaline WH5701—exhibit distinct physiological responses to salinity after long acclimations at optimal and cold growth temperatures. Transcriptomic and photochemical analyses reveal drastic differences in their regulatory strategies and photosynthetic activity across a salinity ...

Effects of the herbicide Roundup on freshwater microbial communities: a mesocosm study [PDF]
, 2007 The impact of the widely used herbicide glyphosate has been mainly studied in terrestrial weed control, laboratory bioassays, and field studies focusing on invertebrates, amphibians, and fishes.

Rhythms of lysis: Viral regulation of prokaryotic turnover across diel cycles
Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.Abstract Diel rhythms structure microbial activity in the ocean, yet the role of viral lysis in driving short‐term community dynamics remains poorly understood. Here, we combined dilution experiments, high‐resolution microbiome sampling and extracellular ribosome sequencing to investigate diel virus–host interactions in the South China Sea. Viral lysis

Nitric oxide supersaturation in the surface waters of the oligotrophic Atlantic Ocean
Limnology and Oceanography Letters, Volume 11, Issue 1, January 2026.Abstract Atmospheric nitric oxide (NO) is a pollutant and climate‐relevant trace gas. Dissolved NO accumulates in the surface ocean and therefore the ocean is a natural source of atmospheric NO. It is generally assumed that NO in the surface ocean is produced photochemically from nitrite (NO2−).
