The Medicago truncatula hypermycorrhizal B9 mutant displays an altered response to phosphate and is more susceptible to Aphanomyces euteiches.
2014
SPE IPM; National audience; Inorganic phosphate (Pi) plays a key role in the development of arbuscular mycorrhizal (AM) symbiosis, which is favoured when Pi is limiting in the environment. We have characterized the Medicago truncatula hypermycorrhizal B9 mutant for its response to limiting (P/10) and replete (P2) Pi. On P2, mycorrhization was significantly higher in B9 plants than in wild-type (WT). The B9 mutant displayed hallmarks of Pi-limited plants, including higher levels of anthocyanins and lower concentrations of Pi in shoots than WT plants. Transcriptome analyses of roots of WT and B9 plants cultivated on P2 or on P/10 confirmed the Pi-limited profile of the mutant on P2 and highli…
Transcriptional response of Medicago truncatula sulphate transporters to arbuscular mycorrhizal symbiosis with and without sulphur stress
2013
Sulphur is an essential macronutrient for plant growth, development and response to various abiotic and biotic stresses due to its key role in the biosynthesis of many S-containing compounds. Sulphate represents a very small portion of soil S pull and it is the only form that plant roots can uptake and mobilize through H(+)-dependent co-transport processes implying sulphate transporters. Unlike the other organically bound forms of S, sulphate is normally leached from soils due to its solubility in water, thus reducing its availability to plants. Although our knowledge of plant sulphate transporters has been growing significantly in the past decades, little is still known about the effect of…

Services provided by soil microorganisms to improve plant phosphate nutrition
2022
Since the first Green Revolution, agricultural practices have been based on the massive use of synthetic fertilisers and plant protection products. Since then, global consumption of phosphate fertilisers has more than tripled, reaching 47 million tonnes in 2019. Current projections estimate that phosphate rock stocks (natural phosphorus resources for fertiliser production) could be depleted within the next century, leading us to change our agricultural practices. In soils, P is mainly present in complexed forms that are not easily accessible to plants. To reduce the use of phosphate fertilisers, it is necessary to make this complexed phosphate accessible to plants. This can be done by benef…
Un établissement rural mérovingien à Delle "La queue au loup" (territoire de Belfort)
2010
This merovingian establishment discovered during an archaeological evaluation to the west of the town of Delle in the Belfort territory is located on the Batte hillside about 300 m from the large Gallo-roman domain on the opposite slope of the valley. This settlement is characterised by a large edifice built of stone and perishable materials, which replaces a timber framed building. The building covers 230 m2 and vestiges of the floors, partitions and interior fittings are preserved which is rare for the period. The analysis of phosphate levels has given indications as to the function of each room. The finds are modest, but they do date, along with radiocarbon analysis, the settlement from …

Le dénigrement de l’autre par le biais de la langue. Une étude pilote dans le domaine du foot en France.
2015
International audience; This article presents an exploratory study that aims to link social sciences, linguistics and sport. Based on the group-focus enmity concept which focuses on existing depreciations among individuals due to their alleged affiliation to a specific social group, we ask how theses alleged social groups treated like entities are concretely devaluated by using words, especially in highly competitive fields like sport. Even this innovative concept is a fundamentally open concept into which further elements can be integrated, we focus on 5 key elements: racism and xenophobia (1), anti-semitism (2), homophobia (3), sexism (4) and anti-capitalism (5). Even this article can onl…
La crise des réfugiés de 2014/2015 sur la base de la résilience sociolinguistique. Une analyse qualitative et comparative entre l’Allemagne et la Fra…
2016
International audience; This article presents preliminary findings of a second enlarged exploratory study embedded in a comprehensive research project in the field of sociolinguistics. Our theoretical approach is based on the resilience concept which we adapted to the field of sociolinguistic. This approach allows us to explore at the same time the co-evolution and co-adaption of interlocutors and language especially by facing a crisis. This analysis shows that especially in Germany the ongoing refugee crisis exacerbates heavily political tensions. The increasing use of « Counter speech » in order to respond to « Hate speech » leads to an « evolutionary and adaptive spiral » in Germany, whe…
Influence of aluminates phases hydration in presence of calcium sulfate on silicates phases hydration : consequences on cements optimum sulfate
2012
The mechanical properties of hydrated cements need to be optimized according to the nature of cement products. Among the factors of optimization, the addition of calcium sulphate intended to regulate the reactivity of tricalcium aluminate (C3A), in quantity and quality in cement is an essential parameter.The advancement of knowledge on the mechanisms of hydration of each cement phase allows a study devoted entirely to the concept of optimum of sulphate. We studied simple system that we complicated and we studied the evolution of hydration, porosity and mechanical properties of cement at different age. The first system studied was the mixture C3S/gypsum, the objective was to determine whethe…
Fructose 2,6-bisphosphate as a signal for changing from sugar to lipid oxidation during flight in locusts
1986
AbstractFlight in locusts is initially powered mainly by carbohydrate but if flight is to be sustained, as in migration, the animals have to utilize fat as the predominant fuel. The molecular basis of this metabolic switch has not been identified. Fructose 2,6-bisphosphate is a potent activator of 6-phosphofructokinase (EC 2.7.1.11) purified from locust flight muscle. After the first few minutes of flight in the locust the concentration of fructose 2,6-bisphosphate in the flight muscle falls dramatically, which should lead to a decrease in the activity of 6-phosphofructokinase as part of the mechanism to conserve carbohydrate during prolonged flight.
