Kleptoplast distribution, photosynthetic efficiency and sequestration mechanisms in intertidal benthic foraminifera

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Foraminifera are ubiquitously distributed in marine habitats, playing a major role in marine sediment carbon sequestration and the nitrogen cycle. They exhibit a wide diversity of feeding and behavioural strategies (heterotrophy, autotrophy and mixotrophy) ...

The symbiotic relationship between educational robotics and computer science in formal education

Francesco Mondada, Barbara Bruno, Jessica Elke Dehler Zufferey, Laila Abdelsalam El-Hamamsy, Frédérique Michèle Chessel-Lazzarotto, Morgane Solène Denise Chevalier

Educational Robotics (ER) has the potential to provide significant benefits to edu-cation, provided an increase in outreach by transitioning from the extra-curricular initiatives in which ER has thrived to formal education. As Computer Science (CS) Educati ...

Growing Ungrowable Bacteria: Overview and Perspectives on Insect Symbiont Culturability

Bruno Lemaitre, Florent François Masson

Insects are often involved in endosymbiosis, that is, the housing of symbiotic microbes within their tissues or within their cells. Endosymbionts are a major driving force in insects' evolution, because they dramatically affect their host physiology and al ...

Transformation of the Drosophila Sex-Manipulative Endosymbiont Spiroplasma poulsonii and Persisting Hurdles for Functional Genetic Studies

Bruno Lemaitre, Florent François Masson, Chloé Christiane Laurence Jollivet

Insects are frequently infected by bacterial symbionts that greatly affect their physiology and ecology. Most of these endosymbionts are, however, barely tractable outside their native host, rendering functional genetics studies difficult or impossible. Sp ...

Tracking the cargo of extracellular symbionts into host tissues with correlated electron microscopy and nanoscale secondary ion mass spectrometry imaging

Anders Meibom, Stéphane Laurent Escrig, Stéphanie Kéren Cohen

Extracellular bacterial symbionts communicate biochemically with their hosts to establish niches that foster the partnership. Using quantitative ion microprobe isotopic imaging (nanoscale secondary ion mass spectrometry [NanoSIMS]), we surveyed localizatio ...

Sub-cellular imaging shows reduced photosynthetic carbon and increased nitrogen assimilation by the non-native endosymbiontDurusdinium trenchiiin the model cnidarian Aiptasia

Anders Meibom

Hosting different symbiont species can affect inter-partner nutritional fluxes within the cnidarian-dinoflagellate symbiosis. Using nanoscale secondary ion mass spectrometry (NanoSIMS), we measured the spatial incorporation of photosynthetically fixed(13)C ...

Blind killing of both male and female Drosophila embryos by a natural variant of the endosymbiotic bacterium Spiroplasma poulsonii

Bruno Lemaitre, Florent François Masson, Samuel Rommelaere, Juan Camilo Paredes Escobar, Mario Gonzalo Garcia Arraez

Spiroplasma poulsonii is a vertically transmitted endosymbiont of Drosophila melanogaster that causes male-killing, that is the death of infected male embryos during embryogenesis. Here, we report a natural variant of S. poulsonii that is efficiently verti ...

Intracellular competition for nitrogen controls dinoflagellate population density in corals

Anders Meibom, Stéphane Laurent Escrig, Maoz Fine, Thomas Krüger, Julia Marie Jeanne Yvonne Bodin, Maria-Evangelia Giovani

The density of dinoflagellate microalgae in the tissue of symbiotic corals is an important determinant for health and productivity of the coral animal. Yet, the specific mechanism for their regulation and the consequence for coral nutrition are insufficien ...

Amoebocytes facilitate efficient carbon and nitrogen assimilation in the Cassiopea -Symbiodiniaceae symbiosis

Anders Meibom, Stéphane Laurent Escrig, Nils Rädecker, Louise Helene Soegaard Jensen, Niclas Heidelberg Lyndby, Sandrine Denise Françoise Bessette

The upside-down jellyfish Cassiopea engages in symbiosis with photosynthetic microalgae that facilitate uptake and recycling of inorganic nutrients. By con- trast to most other symbiotic cnidarians, algal endosymbionts in Cassiopea are not restricted to th ...

A method to disentangle and quantify host anabolic turnover in photosymbiotic holobionts with subcellular resolution

Anders Meibom, Arnaud Comment, Maoz Fine, Emma Mary Gibbin, Guilhem Maurice Louis Banc-Prandi

A wide range of organisms host photosynthesizing symbionts. In these animals the metabolic exchange between host and symbionts has prevented in situ host anabolic turnover to be studied without the confounding effect of translocated photosynthates. Using t ...
