In Vitro Culture of the Insect Endosymbiont Spiroplasma poulsonii Highlights Bacterial Genes Involved in Host-Symbiont Interaction

Bruno Lemaitre, Fanny Schüpfer, Florent François Masson, Mario Gonzalo Garcia Arraez

Endosymbiotic bacteria associated with eukaryotic hosts are omnipresent in nature, particularly in insects. Studying the bacterial side of host-symbiont interactions is, however, often limited by the unculturability and genetic intractability of the symbio ...

The double-edged toxins

Mario Gonzalo Garcia Arraez

Many insect species are associated with endosymbiotic bacteria which have the particularity of living within host tissues. Endosymbionts benefit from this stable and nutritious environment, while providing ecological advantages to their host, such as prote ...

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 ...

Common and unique strategies of male killing evolved in two distinct Drosophila symbionts

Bruno Lemaitre, Toshiyuki Harumoto

Male killing is a selfish reproductive manipulation caused by symbiotic bacteria, where male offspring of infected hosts are selectively killed. The underlying mechanisms and the process of their evolution are of great interest not only in terms of fundame ...

Cellular ultrastructure in benthic foraminifera: general observations and focus on kleptoplasts.

Anders Meibom, Charlotte Madeleine Nicole Lekieffre, Emmanuelle Geslin

Research of the past few decades has revealed a great variability of metabolisms (e.g. adaptation to different microhabitats, feeding strategies, symbiosis, survival to stressful conditions) among benthic foraminiferal species. This metabolic variety is re ...

When neighbours become competitors - Autotrophic assimilation rates of individual symbionts depend on local density when Stylophora pistillata is regularly fed

Anders Meibom, Thomas Krüger, Maoz Fine

The symbiosis between dinoflagellate microalgae and their cnidarian host represents the fundamental mechanism that allows zooxanthellate corals to access the inorganic nutrient pool of the surrounding seawater and conserve and recycle nutrients within thei ...

Stoichiometric N:P flexibility and mycorrhizal symbiosis favour plant resistance against drought

Pierre Rémi Mariotte

Drought induces changes in the nitrogen (N) and phosphorus (P) cycle but most plant species have limited flexibility to take up nutrients under such variable or unbalanced N and P availability. Both the degree of flexibility in plant N:P ratio and of ro ...

Coral photosymbiosis: Linking phylogenetic identity to single cell metabolic activity in mixed symbiont populations

Anders Meibom, Isabelle Domart-Coulon, Maoz Fine, Béatrice Gaume

Tropical reef-building corals live in symbiosis with a wide range of micro-organisms, including unicellular Symbiodinium dinoflagellates also called zooxanthellae. These photosynthetic endosymbionts live inside the coral gastroderm cells. Although corals c ...

Photoacclimatory and photoprotective responses to cold versus heat stress in high latitude reef corals

Thomas Krüger

Corals at the world's southernmost coral reef of Lord Howe Island (LHI) experience large temperature and light fluctuations and need to deal with periods of cold temperature (< 18 °C), but few studies have investigated how corals are able to cope with thes ...

On the origin of primary 1/2 a(0) and a(0) loops in irradiated Fe(Cr) alloys

Robin Schäublin, Anna Prokhodtseva

The radiation-induced primary dislocation loops in thin foils of ultra-high purity Fe and Fe(Cr) model alloys were investigated using ion irradiation in situ in a TEM. In the '111 mechanism' the induced nanometric loops of type a(0) stem from mutual ...
