Characterization of endogenous promoters of GapC1 and GS for recombinant protein expression in Phaeodactylum tricornutum

MicrobiologyOpen, 2021
Although diatoms have been utilized as a cellular factory to produce biopharmaceuticals, recombinant proteins, and biofuels, only a few numbers of gene promoters are available. Therefore, the development of novel endogenous promoters is essential for the

NPF2 is involved in intracellular pH regulation and ion balance in the diatom Phaeodactylum tricornutum

New Phytologist, EarlyView.
Summary Cellular ion and pH homeostasis are crucial factors affecting and regulating metabolic reactions, protein stability, signalling and transport mechanisms. To balance intracellular ion concentrations, organisms need to constantly sense and respond to both the extracellular environment and cell compartments' requests.

Beyond red/far‐red sensing: phytochrome perception of the marine light field by microalgae

New Phytologist, Volume 250, Issue 5, Page 2837-2844, June 2026.
Summary Phytochromes (PHYs) are a major group of photoreceptors, described as red and far‐red light sensors in land plants. Recent genomic and metagenomic explorations have revealed the presence of PHYs also in various eukaryotic microalgae originating from distinct endosymbiotic events.

Divergent responses of the diatom Thalassiosira weissflogii to ocean acidification during light and dark periods

Limnology and Oceanography Letters, Volume 11, Issue 3, May 2026.
Abstract Given the limited understanding of discrepancies in responses of diatoms to ocean acidification (OA), we comparatively investigated the physiological and transcriptional performances of a diatom Thalassiosira weissflogii acclimated to OA (pHt drop of 0.35–0.41) between day and night periods.

Characterization of a GDP-Fucose Transporter and a Fucosyltransferase Involved in the Fucosylation of Glycoproteins in the Diatom Phaeodactylum tricornutum

Frontiers in Plant Science, 2019
Although Phaeodactylum tricornutum is gaining importance in plant molecular farming for the production of high-value molecules such as monoclonal antibodies, little is currently known about key cell metabolism occurring in this diatom such as protein ...

Metacaspases contribute to the cellular response to heat stress in a marine diatom

New Phytologist, Volume 250, Issue 4, Page 2357-2367, May 2026.
Summary Climate‐driven marine heatwaves (HW) are extreme, large‐scale events characterized by elevated ocean temperatures lasting from days to months. Despite their importance, little is known about the molecular mechanisms of algal response to marine HW. Recent studies suggest that metacaspases play an important role in thermotolerance.

Nutrient experiment using Phaeodactylum tricornutum as an assay organism

Brazilian Journal of Oceanography, 1976
The growth of Phaeodactylum tricornutum, cultured at 7,000 lux and 25º C, in twelve-day experiments using enriched water collected at the surface and 50.0 m depth from coastal waters offshore of Ubatuba area, was carried out. Different water enrichements

A New Algivorous Heterolobosean Amoeba, Euplaesiobystra perlucida sp. nov. (Tetramitia, Discoba), Isolated from Pilot-Scale Cultures of Phaeodactylum tricornutum

Microbiology Spectrum, 2023
The diatom Phaeodactylum tricornutum is regarded as a prospective “cell factory” for the high-value products fucoxanthin and eicosapentaenoic acid (EPA). However, contamination with grazing protozoa is a significant barrier to its commercial cultivation.

The Role of Histone Modifications in Plant Priming and Their Analysis by Chromatin Immunoprecipitation

Physiologia Plantarum, Volume 178, Issue 3, May/June 2026.
ABSTRACT Plants are frequently exposed to adverse conditions. Priming, also known as acclimation or hardening, induces stress memory and prepares plants for future challenges by activating defense and protective mechanisms. For this reason, priming is an effective means to maintain plant yield in the face of climate change. Memory behind the priming is
