Quantification of metal-resistant genes from the microbial community of uranium mine soils

2019

Background: Bacteria can thrive in environments presenting unique, extreme and/or stressful conditions, partly due to the diverse resistome they evolved as a result of physiological, metabolic and genetic adaptations. In this context, the microbial communities in soils from abandoned uranium mines may have peculiar genetic profiles that sustain valuable metal-resistance mechanisms. Getting further knowledge on the genetic potential of these microbial communities can be a contribute for developing bioremediation strategies towards the reclamation of highly contaminated uranium mine soils. Objectives: To quantify metal-resistance genes harboured by the microbial community of soil samples coll…

Diversité génétique au sein de la forme spéciale cyclaminis de Fusarium oxysporum et recherche d’un marqueur spécifique

2014

Le cyclamen est la 3e plante fleurie la plus vendue en France. Une des maladies dommageables de cette culture est la fusariose, causée par Fusarium oxysporum f. sp. cyclaminis (FoCy). Cette forme spéciale, inféodée au cyclamen n’est pas différenciable des autres formes spéciales et souches saprophytes. En se développant dans le xylème, FoCy entraîne la mort de la plante. Quand les symptômes externes apparaissent, la plante est condamnée. La lutte chimique est inefficace, la lutte variétale est inexistante, et les mesures prophylactiques sont difficilement applicables. Pour détecter le pathogène précocement et améliorer la lutte, nous nous sommes intéressés à sa diversité génétique. Pour cel…

Image acquisition and processing for precision farming applications

2015

Initially developed for technical industrial sectors such as medicine or aeronautics, imaging technics are more and more used since 30 years in agriculture and viticulture. The development of acquisition tool and the decreasing of the calculation time allowed using imagery in laboratory under controlled conditions. At the beginning of the 90’s, the concept of Precision Farming has been developed in the USA, considering a field as a heterogeneous area needing different input in terms of fertiliser or protection product. In the same time, the aperture of the GPS system for civil applications has allowed the development of remote sensing domain. Combining GPS information and imagery conducted …

No performance reduction at the present northern edge of Ambrosia artemisiifolia L. invasion range

2014

Plant populations at range edges may exhibit reduction of performances and fitness. In the case of biological invasions, such a reduction could be associated with a slowing down of the spread and explain the non-naturalization of a species outside its present invasion range. Common ragweed (Ambrosia artemisiifolia L.) is an ideal model to investigate such processes, since it is invasive in France but not naturalized in northern countries, such as Belgium and the Netherlands. In this study, we test if the performances of ragweed populations vary among different invasion zones. Three populations were selected in each of four invasion zones in Western Europe: 1) French invasion area; 2) northe…

Developing and evaluating tools for assessing the impact of low-dose herbicide nicosulfuron on soil microbial diversity and functioning

2013

Today's conventinal agriculture still relies on the general use of pesticides. Even thought this guarantees production capabilities it also causes environmental pollution having impact on non-targeted organisms. Agricultural practices have been recognized by "The European Soil Framework Directive" as a major threat for soil biodiversity. However, without taking into consideration. recent methodological advances in microbiology, pesticide regulation at EU level relying solely on simple C and N mineralization tè-sts•. ln order to cope with this ECOFUN­-MICROBIODIV project .aim to develop and evaluate tools to estimate the impact of herbicide nicosulfuron on the function and population dynamic…

Expertise Scientifique dans le cadre de l'Exposition grand public : Venenum, un monde empoisonné

2017

Venenum, Un monde empoisonné Que ce soit un moyen de défense ou de pouvoir, une arme mortelle ciblée ou diffuse, une menace environnementale ou encore un espoir pour la médecine de demain, les poisons ont toujours suscité crainte et fascination. Le mot latin venenum désigne aussi bien les poisons élaborés par l'homme que les substance vénéneuses des plantes et des champignons ou encore le venin du serpent.

Fusariose du cyclamen : connaître, détecter et prévenir

2015

SPE Pôle IPM; Fusarium oxysporum est un champignon tellurique ubiquiste présentant une grande diversité de souches pathogènes et non pathogènes. Les souches phytopathogènes sont groupées en formae speciales selon leur spécificité d’hôte. Ainsi, la forma specialis cyclaminis (Focy) est responsable de la fusariose vasculaire du cyclamen. C’est le pathogène le plus destructeur sur cyclamen. Le pathogène, et donc la maladie peuvent intervenir à tout moment du cycle de culture causant d’importantes les pertes. Malheureusement, la détection préventive de Focy n’est pas possible, la lutte chimique inefficace et la résistance variétale inexistante. La lutte biologique apparaît comme l’alternative à…
