The physics of plant morphogenesis: dynamics and mechanics of the plant cell wall in the meristem – MechaStem
The role of physical forces in morphogenesis is widely described as an essential aspect of<br />developmental biology. Nevertheless the contribution of mechanics in shaping organisms is<br />still largely unknown. Building on recent advances from the participants of the project, we<br />will re-examine this issue exploiting new live imaging technologies combined with genetic<br />and micromechanical (atomic force microscopy) approaches.
Chloroplast directed environmental stress acclimation in plants. – CHLORO_SAP
Chloroplasts are essential organelles that are the site of photosynthesis in green plants. Chloroplasts are now at the heart of plant energy metabolism and are delicate sensors of the outside environment and the specific nutrient requirements of the plant. Here we propose to find out how chloroplasts sense environmental change and how they then signal to mediate chloroplast and plant-wide acclimation.
Role of NAXT nitrate excretion transporters in stomatal aperture control and plant tolerance to salinity and drought. – NAXTRESS

Global perspectives on the terrestrialization process – TERRES
land plants. Their study will permit to track the first evolutionary steps of the parent plants, their [...] of land plants, as transitional organisms between acquatic algae and fully terrestrial plants. Spores [...] land plant macrofossils of Devonian age and their biogeographical distribution. Moreover, plant macroremains
Formation, biochemical composition and function of stress-induced cytoplasmic RNP aggregates in Arabidopsis – PLANT RNPBODIES
higher plants will not only provide important insights into their physiological roles in plants, but also [...] the regulation of plant translation during stress, in the mechanisms leading to plant RNA degradation and [...] The capacity of plants to survive exposure to a variety of environmental stresses is of prime importance
Symbiotic Exchange of Signals: Analysis of Molecular Mechanisms in Nod-independent nitrogen fixing symbioses – SESAM
nitrogen-fixing bacteria-plant interactions was the finding, in the early 1990s, that plant-derived flavonoids [...] most important nitrogen-fixing symbioses between plants and microbes. Legumes include important agricultural [...] such as soybean, alfalfa and pea. Actinorhizal plants symbioses with actinobacteria from the genus Frankia
Regulation of plant cell death by the MAPK-IPS1 signalling network – MAPK
Comprendre comment les plantes induisent la mort cellulaire est important pour comprendre qu’est ce qui se passe apres une attaque par des pathogenes mais egalement quand chaque automn des tonnes des feuilles meurent et sont sacrifiees par des plantes vivaces.
Perception of lipo-chitooligosaccharides and roles of their putative receptors in non legumes – LCOinNONLEGUMES
Plants interact with some beneficial soil microorganisms (bacteria and fungi) which provide them with nutrients. These interactions require recognition by plants of chemical signals produced by the microorganism.
Plastid/nucleus interactions during plant development – IPNODEV
The goal of this project is to investigate cellular mechanisms involved in the control of chloroplast division by the nucleus and reciprocally in the regulation of cell proliferation and differentiation by chloroplast-derived signals.
XopAC-triggered vascular immunity in plants – XOPAQUE
The phytopathogenic bacterium Xanthomonas campestris pv. campestris (Xcc) is the causal agent of black rot in Brassicaceae (Cabbages, turnip, radish, Arabdopsis,...). To infect the plant, Xcc injects type III proteins in the plant cell to manipulate plant physiology and/or immunity. In the frame of the ANR Xopaque, we will search for xopAC targets in Arabidopsis plants resistant or susceptible to Xanthomonas.
