• The activation of the mTOR pathway supports lysosome biogenesis in the sea urchin embryo · 2026

  Résumé de la publication : The mTOR pathway controls the balance between anabolic and catabolic activities in animal cells, acting as a key coordinator of metabolic homeostasis. In fact, the activation of this conserved regulatory circuit promotes the biosynthesis of different macromolecules, including proteins, lipids and nucleic…

• Gametophyte Thermal Priming Modifies the Transcriptomic Heat Stress Response of Sporophyte Progeny in Saccharina latissima · 2026

  Résumé de la publication : Saccharina latissima (sugar kelp) is a brown macroalga that forms kelp forests along North Atlantic coasts, playing a key role in coastal ecosystems. It is also of growing economic importance as the dominant species used in European kelp aquaculture. Both wild and…

• Genome variations reveal rapid adaptation to domestication and habitat changes in the brown algae Saccharina japonica · 2026

  Résumé de la publication : Introduction: Saccharina japonica, the first domesticated marine plant in global aquaculture, has been cultivated for nearly a century, adapting to diverse marine environments in China. This domestication has led to significant genetic changes, but the genomic mechanisms driving these adaptations remain unclear.…

• Functional roles of mastigonemes in Ectocarpus gamete swimming revealed by CRISPR-Cas9 mutagenesis · 2026

  Résumé de la publication : Mastigonemes on the anterior flagellum (AF) of flagellated Stramenopiles (which includes diverse organisms such as diatoms, brown algae, oomycetes and others) are tripartite tubular structures. We investigated the functions of mastigonemes in gametes of the brown alga Ectocarpus species 7 strain Ec32…

• Fructan utilization by members of marine Gammaproteobacteria involves SusC/D-like proteins · 2026

  Résumé de la publication : Fructans are ubiquitous in terrestrial ecosystems, however, these glycans are underexplored in the marine environment. We have discovered that the Antarctic gammaproteobacterium Pseudoalteromonas distincta is highly adapted to the degradation of fructose-containing substrates. This is enabled by proteins encoded in several genomic…
