Importance of mixotrophic flagellates during the ice-free season in lakes located along an elevational gradient

Mixotrophy seems to be widespread among phytoplankton, but whether this strategy is more relevant in oligotrophic lakes remains unclear. Here, we tested the hypothesis that the relative abundance of mixotrophic flagellates in lakes increases along an eleva ...

Vibrio cholerae filamentation promotes chitin surface attachment at the expense of competition in biofilms

Alexandre Louis André Persat

Collective behavior in spatially structured groups, or biofilms, is the norm among microbes in their natural environments. Though biofilm formation has been studied for decades, tracing the mechanistic and ecological links between individual cell morpholog ...

Rapid Recruitment of Symbiotic Algae into Developing Scleractinian Coral Tissues

Thomas Bockel

While the early acquisition of Symbiodiniaceae algae into coral host tissues has been extensively studied, the dynamics of the migration of algal cells into rapidly expanding coral tissues still lacks a systematic study. This work examined two Red Sea bran ...

Elevated CO2 Leads to Enhanced Photosynthesis but Decreased Growth in Early Life Stages of Reef Building Coralline Algae

Niclas Heidelberg Lyndby, Michael Kühl

Crustose coralline algae (CCA) are key organisms in coral reef ecosystems, where they contribute to reef building and substrate stabilization. While ocean acidification due to increasing CO2 can affect the biology, physiology and ecology of fully developed ...

ZFP30 promotes adipogenesis through the KAP1-mediated activation of a retrotransposon-derived Pparg2 enhancer

Didier Trono, Bart Deplancke, Julien Léonard Duc, Julie Marie Russeil, Riccardo Dainese, Marco Cassano, Michaël Imbeault, Sunil Kumar Raghav, Petra Catalina Schwalie, Suk Min Jang, Wanze Chen, Evgeniia Pankevich

Krüppel-associated box zinc finger proteins (KZFPs) constitute the largest family of mammalian transcription factors, but most remain completely uncharacterized. While initially proposed to primarily repress transposable elements, recent reports have revea ...

Temperature and feeding induce tissue level changes in autotrophic and heterotrophic nutrient allocation in the coral symbiosis – A NanoSIMS study

Anders Meibom, Stéphane Laurent Escrig, Thomas Krüger, Maoz Fine, Julia Marie Jeanne Yvonne Bodin, Céline Edith Loussert-Fonta

Corals access inorganic seawater nutrients through their autotrophic endosymbiotic dinoflagellates, but also capture planktonic prey through heterotrophic feeding. Correlating NanoSIMS and TEM imaging, we visualized and quantified the subcellular fate of a ...

Short-Term Thermal Acclimation Modifies the Metabolic Condition of the Coral Holobiont

Anders Meibom, Thomas Krüger, Emma Mary Gibbin, Julia Marie Jeanne Yvonne Bodin

The nutritional symbiosis between coral hosts and photosynthetic dinoflagellates is fundamental to the functioning of coral reefs. Rising seawater temperatures destabilize this relationship, resulting in drastic declines in world-wide coral cover. Thermal ...

Eco-Evolutionary Dynamics Linked to Horizontal Gene Transfer in Vibrios

Melanie Blokesch, Frédérique Marie Jeanne Le Roux

Vibrio is a genus of ubiquitous heterotrophic bacteria found in aquatic environments. Although they are a small percentage of the bacteria in these environments, vibrios can predominate during blooms. Vibrios also play important roles in the degradation of ...

Marine and freshwater micropearls: biomineralization producing strontium-rich amorphous calcium carbonate inclusions is widespread in the genus Tetraselmis (Chlorophyta)

Michaël Bensimon, Montserrat Filella

Unicellular algae play important roles in the biogeochemical cycles of numerous elements, particularly through the biomineralization capacity of certain species (e.g., coccolithophores greatly contributing to the "organic carbon pump" of the oceans), and u ...

DNA-uptake pilus of Vibrio cholerae capable of kin-discriminated auto-aggregation

Melanie Blokesch, Sandrine Stutzmann, Candice Stoudmann, David William Adams

Natural competence for transformation is a widely used and key mode of horizontal gene transfer that can foster rapid bacterial evolution. Competent bacteria take-up DNA from their environment using Type IV pili, a widespread and multi-purpose class of cel ...
