Exclusion of root competition increases competitive abilities of subordinate plant species through root-shoot interactions

Alexandre Buttler, Pierre Rémi Mariotte, Charlotte Vandenberghe, Aurélie Thébault

Questions What is the importance of root competition in the competitive abilities of dominant and subordinate species? Location Pair-wise greenhouse experiment based on field data from a semi-natural grassland community in the Swiss Jura Mountains (Col du ...

Atomic Force Microscopy Stiffness Tomography on Living Arabidopsis thaliana Cells Reveals the Mechanical Properties of Surface and Deep Cell-Wall Layers during Growth

Giovanni Dietler, Sandor Kasas, Charles Roduit, Christian Fankhauser

Cell-wall mechanical properties play a key role in the growth and the protection of plants. However, little is known about genuine wall mechanical properties and their growth-related dynamics at subcellular resolution and in living cells. Here, we used ato ...

Metal accumulation and response of antioxidant enzymes in seedlings and adult sunflower mutants with improved metal removal traits on a metal-contaminated soil

Jean-Paul Schwitzguebel, Erika Nehnevajova

Sunflower mutant lines with an enhanced tolerance and metal accumulation capacity obtained by mutation breeding have been proposed for Zn, Cd and Cu removal from metal-contaminated soils in previous studies. However, soils contaminated with trace elements ...

Over-expression of PHO1 in Arabidopsis leaves reveals its role in mediating phosphate efflux

Michaël Bensimon, Charles Vidoudez

P>Inorganic phosphate (Pi) homeostasis in multi-cellular eukaryotes depends not only on Pi influx into cells, but also on Pi efflux. Examples in plants for which Pi efflux is crucial are transfer of Pi into the xylem of roots and release of Pi at the peri- ...

Skeletal growth, ultrastructure and composition of the azooxanthellate scleractinian coral Balanophyllia regia

Anders Meibom, Jaroslaw Hubert Stolarski, Isabelle Domart-Coulon

The biomineralization process and skeletal growth dynamics of azooxanthellate corals are poorly known. Here, the growth rate of the shallow-water dendrophyllid scleractinian coral Balanophyllia regia was evaluated with calcein-labeling experiments that sho ...

Understanding engraftment of cultured epidermal stem cells

Nicolas Grasset

The epidermis and its appendages protect our body from environmental hazards. Cells generated in the basal layer continuously replace the terminally differentiated keratinocytes that are shed off the epidermal surface. Long-term renewal depends on specific ...

From gut homeostasis to cancer

Freddy Radtke

The mammalian intestine has one of the highest turnover rates in the body. The intestinal epithelium is completely renewed in less than a week. It is divided into spatially distinct compartments in the form of finger-like projections and invaginations that ...

Antero-posterior patterning of the vertebrate digestive tract: 40 years after Nicole Le Douarin's PhD thesis

Anne Grapin-Botton

This review is dedicated to the work on chick digestive tract organogenesis that Nicole Le Douarin performed as a PhD student under the direction of Etienne Wolf. I discuss how she laid the grounds for future work by establishing fate maps at somitic stage ...

A single gene that promotes interaction of a phytopathogenic bacterium with its insect vector, Drosophila melanogaster

Bruno Lemaitre

Insects are major vectors of plant and animal disease, and bacterial phytopathogens are often disseminated by flies. We have previously reported that some isolates of the phytopathogenic bacterial species Erwinia carotovora infect Drosophila and activate a ...

Sensitivity of polarized epithelial cells to the pore-forming toxin aerolysin

Françoise Gisou van der Goot Grunberg, Laurence Gouzi Abrami

Aerolysin is one of the major virulence factors produced by Aeromonas hydrophila, a human pathogen that produces deep wound infection and gastroenteritis. The toxin interacts with target mammalian cells by binding to the glycan core of glycosylphosphatidyl ...
