In the actual context, biopesticides have emerged as a main alternative to conventional agriculture1. Hence, elicitors are metabolites naturally produced by microorganisms, pathogenic or not, and plants which are able to induce the natural resistance of plants. Also, they have proved to be excellent candidates for biological control. In this context, the lipoxygenase pathway leads to the formation of fatty acid degradation products, called oxylipins, which appear to be crucial agents in plant defence mechanisms2,3. Moreover, with their broad spectrum of action and their possible inducibility, oxylipins appear to be promising candidates for their use as elicitors4. This work focuses on two hydroperoxy-derived oxylipins, the 13(S)-hydroperoxy-octadecadienoic acid (13-HPOD) and the 13(S)-hydroperoxy-octadecatrienoic acid (13-HPOT). The study of the interaction of such compounds with representative plant plasma membrane lipids is essential to understand plant resistance mechanisms. Several in silico and experimental techniques of biophysics showed that acyl-hydroperoxides have significant adsorption capacity and a strong affinity for model membranes. They may also penetrate biological membrane but no permeabilisation effect was observed in this work. Slight conformational differences seem to have a significant impact on their ability to interact with plant plasma membranes. Based on these results, further investigation of the interactions of fatty acids hydroperoxides, even more on the 9-forms, with plant plasma membranes and eventually in the presence of phytopathogenic species, would allow a better understanding of the innate immunity and, on the longer term, could lead to the development of new elicitors with biological mechanisms potentially independent of membrane protein receptors.

Antioxidants are enzymes, non-enzymatic proteins, minerals micronutrients, vitamins, phenolic compounds, pigments and others. Polyphenols have the ability to reduce or prevent damage caused by free radicals promoting positive effects on human health due to their antioxidant capacity. In this study we evaluated the content of polyphenols from several commercial biological (n = 6) and conventional juices (n = 6 ) (orange, blackcurrant, apple, grapes, tomato, carrot, pomegranate, lemon, grapefruit juices) and we determined the antioxidant effect by inhibition of the superoxide anion production measured by chemiluminescence technology. Conventional juices (orange, apple, tomato, pomegranate, lemon, grapefruit juices) showed more total polyphenolics (+ 32%), more flavan-3-ols (+ 67%) and more flavonols (+ 42%) than the same biological juices. The presence of anthocyanins was reported in juices made with blackcurrant, pomegranate and grapes only, with values above 50 µg/mL, regardless of their nature. Surprisingly, chemiluminescence results showed an inhibition in superoxide anion production by 51% for biological juices vs 23% in conventional ones. The correlation between total polyphenol content and antioxidant capacity of all the juices was r = 0.83 (r2 = 0.7). The fact that there is less polyphenols and higher antioxidant activity in bio juices could be related to the concentration and the type of polyphenol present. [less ▲]

In animal models, the severity of cartilage damage is assessed by histological scores evaluating the structure, the proteoglycan content, the integrity of the tidemark, the cellularity, and osteophytes. In parallel to these histological analyzes, we studied the mechanical properties of cartilage at different stages of disease progression in the Dunkin-Hartley guinea pigs. We also correlated the severity of histological lesions with the mechanical properties of cartilage. [less ▲]

Zinc and iron are two essential micronutrients for plants. The homeostasis networks of the two metals are intertwined. Arabidopsis halleri is a zinc- and cadmium-tolerant and zinc-hyperaccumulating species, which also present adaptation of its iron homeostasis(1,4). Transcriptomic studies identified genes which are constitu-tively over-expressed in Arabidopsis halleri compared to Arabidopsis thaliana and which may have a role in metal tolerance or accumulation(2-4). Among them, a candidate gene encodes the FRD3 (FERRIC REDUCTASE DEFECTIVE 3) protein, a member of the MATE family of membrane transporters. FRD3 is a citrate transporter involved in iron homeostasis(5-7) and plays a role in zinc tolerance in A. thaliana(8). The FRD3 gene displays a complex regulation. In A. thaliana, alternative transcript initiation for FRD3 determines two transcripts, which dif-fer in their 5'UTRs and have differential translation efficiency. The two transcripts are selectively regulated under stress conditions: iron and zinc depletion, zinc excess or cadmium presence(9). In A. halleri, a single highly ex-pressed FRD3 transcript with high translation efficiency is present(9). [less ▲]

Confronté à des questions qui touchent à l'éthique, quelle conduite argumentative va mobiliser un petit groupe d'intervenants pour débattre des questions posées? Plus concrètement, quel sera le degré d'argumentativité du discours? Quelle est la visée des échanges : convaincre ou persuader? Quels types d'arguments seront convoqués? Sur quelles valeurs se fonderont-ils? Quels phénomènes de contre-argumentation émergeront? L'atelier, pratique, consiste à mettre en situation les participants (profs de philo au primaire, au secondaire ou au supérieur) de débattre ou d'analyser un débat. [less ▲]
