Multi‐proxy sequence stratigraphy of a mixed carbonate–siliciclastic shelf across the Jurassic–Cretaceous transition

The Depositional Record, Volume 12, Issue 4, September 2026.
An integrated facies, MS and XRF‐based approach applied to the Tithonian–Berriasian Sidi Khalif Formation (central Tunisia) resolves five Tithonian and eight Berriasian third‐order sequences, showing how mixed carbonate–siliciclastic shelves record coupled eustatic, climatic and tectonic controls and providing a transferable template for similar mud ...

Comparison of Five TRIzol-Based Protein Preparation Methods for 2-DE Production From Challenging Marine Dinoflagellate Samples: A Case Study on Two Benthic Prorocentrum Species

Journal of Marine Science and Engineering, 2020
Two-dimensional gel electrophoresis (2-DE) is a major element of conventional gel-based proteomics, which resolves complex protein mixtures. Protein extraction with the removal of interfering substances from the sample remains the key to producing high ...

Compound Hypoxia With Heat or Acidification Stress Induces Synergistic and Additive Effects on Coral Physiology

Global Change Biology Communications, Volume 1, Issue 3, September 2026.
Multi‐stressor experiments on three coral species demonstrate hypoxia produces mostly additive effects with acidification but synergistically amplifies physiological stress under elevated temperatures. As global and local environmental change increase compound stress events on coral reefs, distinguishing hypoxia‐driven effects and interactive stressor ...

Diverse Bacterial PKS Sequences Derived From Okadaic Acid-Producing Dinoflagellates

Marine Drugs, 2008
Okadaic acid (OA) and the related dinophysistoxins are isolated from dinoflagellates of the genus Prorocentrum and Dinophysis. Bacteria of the Roseobacter group have been associated with okadaic acid producing dinoflagellates and have been previously ...

Giant phytoplankton revealed by in situ imaging

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract Deployment of an autonomous Zooglider in the western Mediterranean Sea revealed the presence of long phytoplankton chains attaining maximum lengths of 6.4–10.4 mm suspended in situ. Elongate chains included the diatoms Guinardia, Proboscia, two other diatom morphologies, and solitary filaments of the cyanobacterium Trichodesmium. Most elongate

Transcriptome Analysis of Scrippsiella trochoidea CCMP 3099 Reveals Physiological Changes Related to Nitrate Depletion

Frontiers in Microbiology, 2016
Dinoflagellates are a major component of marine phytoplankton and many species are recognized for their ability to produce harmful algal blooms (HABs).

Metatranscriptomics analysis of silicon transporters highlights underappreciated contributors to silica cycling in the Baltic Sea

Limnology and Oceanography Letters, Volume 11, Issue 5, September 2026.
Abstract The biotic component of the marine silica cycle strongly influences global biogeochemical cycling. Active uptake of dissolved silicic acid (dSi) occurs via silicon transporters (SITs), first characterized in diatoms but widely distributed in eukaryotes. Studying SITs and SIT‐like (SIT‐L) gene transcripts provides insights into the dynamics and

Fugacium Spliced Leader Genes Identified from Stranded RNA-Seq Datasets

Microorganisms, 2019
Trans-splicing mechanisms have been documented in many lineages that are widely distributed phylogenetically, including dinoflagellates. The spliced leader (SL) sequence itself is conserved in dinoflagellates, although its gene sequences and arrangements

Changes in photosynthesis and grazing facilitate growth of a mixotrophic protist under ocean acidification and warming

New Phytologist, Volume 251, Issue 5, Page 2574-2587, September 2026.
Grazing rates of Ochromonas CCMP2951 expressed as carbon obtained per mean cell volume (a) and Caut/het‐photosynthetically fixed carbon divided by carbon obtained through grazing (b) in the four experimental treatments. Summary Mixotrophic protists capable of both photosynthesis and phagotrophy are key members of marine plankton communities.

Genome Manipulation in Microalgae: A Systematic Map on Improved Traits, Strains, and Their Commercial Applications

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Microalgae are promising platforms for producing diverse biocompounds relevant to multiple commercial sectors, and the use of genomic technologies in microalgae is rapidly expanding. To examine the research trends, we conducted a bibliographic analysis (systematic map) of this rapidly developing field. Our study presents a descriptive overview
