Ultrastructure and distribution of kleptoplasts in benthic foraminifera from shallow-water (photic) habitats

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Assimilation, sequestration and maintenance of foreign chloroplasts inside an organism is termed “chloroplast sequestration” or “kleptoplasty”. This phenomenon is known in certain benthic foraminifera, in which such kleptoplasts can be found both intact an ...

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 ...

Cellular pathways of carbon and nitrogen assimilation in kleptoplastic foraminiferal species

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Kleptoplasty is the process by which an organism sequesters algal chloroplasts while discarding or digesting other algal components. This ability is encountered in different organisms, including benthic foraminifera. Among kleptoplastic foraminiferal speci ...

Essential Nucleoid Associated Protein mIHF (Rv1388) Controls Virulence and Housekeeping Genes in Mycobacterium tuberculosis

Stewart Cole, Nina Theres Odermatt, Claudia Sala, Andrej Benjak

Tight control of gene expression is crucial for Mycobacterium tuberculosis to adapt to the changing environments encountered when infecting or exiting human cells. While three nucleoid associated proteins (NAPs) EspR, HupB and Lsr2 have been investigated, ...

Sequestered Chloroplasts In The Benthic Foraminifer Haynesina Germanica: Cellular Organization, Oxygen Fluxes And Potential Ecological Implications

Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Haynesina germanica is a coastal benthic foraminifer known to sequester chloroplasts from benthic pennate diatoms. This study investigates its cellular organization, as well as the oxygen consumption and production rates under dark and light conditions. Th ...

Rv3852 (H-NS) of Mycobacterium tuberculosis Is Not Involved in Nucleoid Compaction and Virulence Regulation

Stewart Cole, Nina Theres Odermatt, Claudia Sala, Andrej Benjak, Anthony Vocat, Gaëlle Séraphine Kolly, Andréanne Lupien

A handful of nucleoid-associated proteins (NAPs) regulate the vast majority of genes in a bacterial cell. H-NS, the histone-like nucleoid-structuring protein, is one of these NAPs and protects Escherichia coli from foreign gene expression. Though lacking a ...

Hyperplectonemes: A Higher Order Compact and Dynamic DNA Self-Organization

Giovanni Dietler, Paolo De Los Rios, Giovanni Longo, Fabrizio Benedetti, Aleksandre Japaridze

Bacterial chromosome has a compact structure that dynamically changes its shape in response to bacterial growth rate and growth phase. Determining how chromatin remains accessible to DNA binding proteins, and transcription machinery is crucial to understan ...

Centriole Biogenesis: From Identifying the Characters to Understanding the Plot

Pierre Gönczy, Niccolo Banterle

The centriole is a beautiful microtubule-based organelle that is critical for the proper execution of many fundamental cellular processes, including polarity, motility, and division. Centriole biogenesis, the making of this miniature architectural wonder, ...
