Effect of incorporation of Brassica napus L. residues in soils on mycorrhizal fungus colonisation of roots and phosphorus uptake by maize (Zea mays L…

2007

International audience; Plants in the Brassicaceae family are known to contain thioglucoside compounds that produce isothiocyanates when tissues are disrupted. These chemicals have a negative effect on soil-borne fungal pathogens, and possibly on vesicular-arbuscular mycorrhizal (AM) fungi. We investigated the effect of incorporation of Brassica napus L. residues in a soil on mycorrhizal colonisation of roots, P uptake and growth of following maize (Zea mays L.) crop. A pot experiment was carried out in a glasshouse with pre-inoculation with Glomus intraradices (+I and -I), incorporation of B. napus L. residues (+R and -R) and mineral P fertilization (+P and -P) as studied factors. The soil…

Methods for studying root colonization by introduced beneficial bacteria

2003

e-Book; Some free-living rhizobacteria are considered as potential biocontrol and plant growth-promoting agents. Successful application of beneficial bacteria as microbial inoculants requires their presence and activity at the appropriate level, but even more, at the right time and place. Various markers are described in the literature to differentiate introduced bacteria from indigenous microflora and to visualize them. These markers are presented together with the methods currently applied to quantify bacterial densities and to characterize the distribution of introduced bacteria. The methods to quantify bacterial densities are either based on bacterial cultivation or not. Different types…

Etude du rôle d'un donneur de monoxyde d'azote (Glycéryl Trinitrate) dans la mort cellulaire immunogène induite par des chimiothérapies (FOX) et/ou r…

2017

Le cancer colorectal se situe au 3ème rang mondial des cancers les plus fréquents derrière les cancers du sein et du poumon. Dans le cas de cancer colorectal métastatique, la première ligne thérapeutique repose sur l’utilisation d’une association de chimiothérapies : le FOLFOX (acide FOLinique, 5-Fluorouracile et OXaliplatine). Malgré une forte efficacité anti-tumorale de cette combinaison, de nombreuses rechutent apparaissent nécessitant l’utilisation de nouvelles stratégies basées sur l’association du FOLFOX à d’autres agents anti-cancéreux ou stimulant le système immunitaire. Cette étude a eu comme objectif d’étudier l’effet anti-tumoral del’association du FOX (5-Fluorouracile et OXalipl…

Genes encoding transcription factors in Glomus intraradices and their expression at the appressoria stage of arbuscular mycorrhiza interactions

2007

International audience; Molecular pathways governing the life cycle of arbuscular mycorrhizal (AM) fungi and their symbiotic interactions with root tissues are not yet fully understood. Most studies fo fungal responses to host plants have targeted developmental stages before root contact (germinating spores), or after root colonization (intraradical mycelium). We are focusing on the early cell events of appressoria contact with the root surface which are essential to the successful outcome of the AM symbiosis. Recent monitoring of Glomus intraradices gene expression at this stage has revealed differential fungal responses to roots of host and non-host (Myc- mutants) M. truncatula (Seddas et…

Mise en place d'un modèle in vivo de colonisation digestive stable à C. Abicans chez la souris immunocompétente

2012

Les levures du genre Candida sont des agents pathogènes opportunistes responsables de candidoses invasives chez les sujets immunodéprimés, et sont associées à un taux de mortalité élevé. Elles représentent 8 à 15% des infections nosocomiales hématogènes et Candida albicans est l’espèce la plus fréquemment isolée en pathologie humaine. Initialement C. albicans appartient à la flore commensale intestinale, buccale et vaginale de l’homme. Ce commensalisme résulte d’un équilibre entre les propriétés biologiques de la levure et les systèmes de défense de l’hôte. La rupture de cet équilibre chez un patient fragilisé aura pour conséquence une colonisation intense des muqueuses favorisant un envahi…

Do the high phenotypic plasticity of A. artemisiifolia L. explain its invasive success in France?

2008

International audience; Ambrosia artemisiifolia (Asteraceae) is an invasive annual plant introduced from North America to Europe over 100 years ago. This plant species is now widespread in numerous countries all over the world, causing damages to agricultural crops and human health. Ambrosia artemisiifolia is spreading as a weed in many field crops but is also able to invade a wide range of areas such as various human disturbed habitats or riverbanks (Figure 1). A considerable variability of the life history traits of A. artemisiifolia was previously observed among and within different populations (Fumanal et al., 2007). Since the success of colonization of some invasive plant species may r…

Les variétés de melon résistantes à la fusariose favorisent-elles dans leur rhizosphère la multiplication de souches pathogènes agressives ?

2012

http://prodinra.inra.fr/record/270428 SPE IPM CT2 (vu AB); Master; Au sein de l’espèce Fusarium oxysporum, champignon tellurique, il existe des souches pathogènes et des souches non pathogènes. Parmi les espèces phytopathogènes, il existe 120 formes spéciales, chacune caractéristique de l’espèce qu’elles infectent. La forme spéciale melonis colonise les racines du melon et s’installe dans le système vasculaire provoquant un jaunissement et un flétrissement des parties aériennes. Ces dix dernières années, malgré l’utilisation de variétés partiellement résistantes, on assiste à une augmentation de l’incidence et de la gravité de la fusariose du melon, les souches isolées étant de plus en plus…
