The membrane proteome of Medicago truncatula roots displays qualitative and quantitative changes in response to arbuscular mycorrhizal symbiosis

2014

International audience; Arbuscular mycorrhizal (AM) symbiosis that associates roots of most land plants with soil-borne fungi (Glomeromycota), is characterized by reciprocal nutritional benefits. Fungal colonization of plant roots induces massive changes in cortical cells where the fungus differentiates an arbuscule, which drives proliferation of the plasma membrane. Despite the recognized importance of membrane proteins in sustaining AM symbiosis, the root microsomal proteome elicited upon mycorrhiza still remains to be explored. In this study, we first examined the qualitative composition of the root membrane proteome of Medicago truncatula after microsome enrichment and subsequent in dep…

Détection non supervisée des adventices par drone : résultats et limites

2019

Dans un cadre de diminution des produits phytosanitaires, l'agriculture de précision est une solution technique pour diminuer l'impact environnemental de l'agriculture sans transformer les systèmes de production actuels. La démocratisation des drones aériens pour l'agriculture permet leur utilisation afin de discriminer culture et adventices au sein de parcelles cultivées. Nous avons développé et testé des algorithmes non supervisés (ne nécessitant pas l’intervention d’un humain) combinant l'information spatiale et spectrale pour réaliser cette discrimination. Cette présentation sera l'occasion de revenir sur les résultats de ces algorithmes et de présenter également les limites rencontrées…

Label-free 1-DE-LC-MS/MS to identify arbuscular mycorrhiza-related membrane proteins

2012

Deep changes in the shape and number of organelles, together with profound modifications in various membrane compartments, are induced within arbuscular mycorrhizal (AM) symbiosis. In this context, to investigate the membrane-associated proteins that are regulated in the model interaction Medicago truncatula – Rhizophagus irregularis, label-free 1DE-LC-MS/MS approach has been employed as alternative to two-dimensional gel electrophoresis. The existence of a correlation between protein abundance and peak areas or number of MS/MS spectra has widened the choice of label-free quantitative proteomics. The results highlighted microsomal protein candidates that could be involved in the symbiotic e…

La Méditerranée comme mer carnivore. Sidérer pour penser l’accueil dans Como si nunca hubieran sido de Javier Gallego «Crudo» et Juan Gallego

2021

International audience; La Méditerranée, véritable cimetière migratoire, est devenue la frontière la plus dangereuse au monde pour les migrants irréguliers. Porter un regard sur ceux qui passent oblige incontestablement à questionner les politiques d’accueils. Nous proposons d’interroger un objet hybride qui se situe entre la bande dessinée et la poésie : Como si nunca hubieran sido (Madrid : Reservoir Books, 2018) de Javier Gallego « Crudo » et Juan Gallego. Un ouvrage qui interroge le projet européen face aux enjeux des migrations politiques, économiques, climatiques. Nous analyserons les formes de sidération qui permettent de penser les vies qui comptent et celles que l’on ne compte que …

Texture et paradoxes auditifs dans la musique récente de Michaël Levinas

2020

Parmi les courants musicaux apparus après 1945, le spectralisme a été celui dont les fondements théoriques, les techniques d’écriture et les sources d’inspiration ont été le plus fécondés par les recherches en acoustique, en psychoacoustique et en perception de la musique. Les questionnements musicaux de Michaël Levinas, comme ceux de Grisey, Murail, Dufourt, Saariaho, Hurel, Dalbavie, Maresz et d’autres, se sont nourris de notions telles que spectre, transitoires, résonance, battements, sons de combinaison, inharmonicité, rugosité, seuil perceptif,masquage, effet Doppler, etc. Cependant, s’il partage avec ses collègues ce socle de connaissances, elles ne l’ont pas conduit aux mêmes solutio…

A 3D multispectral integrated acquisition system : acquisition, data coding and compression

2010

We have developed an integrated system permitting the simultaneous acquisition of the 3D shape and the spectral spectral reflectance of scanned object surfaces. We call this system a 3D multispectral scanner because it combines within a stereopair, a multispectral video camera and a structured light projector. We see several application possibilities for a such acquisition system but we want to highlight applications in the field of digital archiving and broadcasting for heritage objects. In the manuscript we first introduce the acquisition system and its necessary calibrations and treatments needed for his use. Then, once the acquisition system is functional, data that are generated are ri…

Integration of high resolution spatial and spectral data acquisition systems for monitoring purposes in cultural heritage applications

2013

The concern and interest of this PhD thesis is the registration of featureless 3D and multispectral datasets describing cultural heritage objects.In this context, there are few natural salient features between the complementary datasets, and the use of targets is generally proscribed.We thus develop a technique based on the photogrammetric tracking of the acquisition systems in use.A series of simulations was performed to evaluate the accuracy of our method in three configurations chosen to represent a variety of cultural heritage objects.These simulations show that we can achieve a spatial tracking accuracy of 0.020 mm and an angular accuracy of 0.100 mrad using four 5 Mpx cameras when dig…
