Occurrence and distribution of endobacteria in the plant-associated mycelium of the ectomycorrhizal fungus Laccaria bicolor S238N Inra
Bertaux, J.; Schmid, M.; Hutzler, P.; Hartmann, A.; Garbaye, J.; Frey-Klett, P..
Fluorescence in situ hybridization, associated with confocal laser scanning microscopy or epifluorescence microscopy with deconvolution system, has allowed the detection of a community of intracellular bacteria in non-axenic samples of the ectomycorrhizal fungus Laccaria bicolor S238N. The endobacteria, mainly alpha -proteobacteria, were present in more than half of the samples, which consisted of ectomycorrhizae, fungal mats and fruit bodies, collected in the glasshouse or in the forest. Acridine orange staining suggests that the endobacteria inhabit both live and dead fungal cells. The role of these endobacteria remains to be clarified.

PathOrganic – Risks and Recommendations Regarding Human Pathogens in Organic Vegetable Production Chains Organic Eprints
Arthurson, V.; Baggesen, D.; Brankatschk, K.; Dalsgaard, A.; Duffy, B.; Fenzl, C.; Friedel, J.K.; Hackl, E.; Hartmann, A.; Hedin, F.; Hofmann, A.; Jäderlund, L.; Jansson, J.; Jensen, A.N.; Koller, M.; Mäder, P.; Rinnofner, T.; Schmid, M.; Storm, C.; van Bruggen, A.H.C.; Widmer, F.; Wyss, G.S.; Zijlstra, C.A.; Sessitsch, A..
PathOrganic assesses risks associated with the consumption of fresh and minimally processed vegetables due to the prevalence of bacterial human pathogens in plant produce. The project evaluates whether organic production poses a risk on food safety, taking into consideration sources of pathogen transmission (e.g. animal manure). The project also explores whether organic versus conventional production practices may reduce the risk of pathogen manifestation. In Europe, vegetable-linked outbreaks are not well investigated. A conceptual model together with novel sampling strategies and specifically adjusted methods provides the basis for large-scale surveys of organically grown plant produce in five European countries. Critical control points are...

Plant-driven selection of microbes Inra
Hartmann, A.; Schmid, M.; Van Tuinen, D.; Berg, G..
The rhizodeposition of plants dramatically influence the surrounding soil and its microflora. Root exudates have pronounced selective and promoting effects on specific microbial populations which are able to respond with chemotaxis and fast growth responses, such that only a rather small subset of the whole soil microbial diversity is finally colonizing roots successfully. The exudates carbon compounds provide readily available nutrient and energy sources for heterotrophic organisms but also contribute e.g. complexing agents, such as carboxylates, phenols or siderophores for the mobilization and acquisition of rather insoluble minerals. Root exudation can also quite dramatically alter the pH- and redox-milieu in the rhizosphere. In addition, not only...

Surveying Pathogenic Bacteria in Vegetables Organic Eprints
Hackl, E.; Arthurson , V.; Baggesen, D.; Brankatschk, K.; Duffy , B.; Fenzl, C.; Friedel, J.K.; Hedin, F.; Hofmann, A.; Jensen , A.N.; Jäderlund, L.; Koller, M.; Rinnofner, T.; Schmid, M.; Storm , C.; Wyss, G.S.; Sessitsch, A..
Bacterial pathogens have increasingly been identified as disease causing agents in vegetable-linked outbreaks. Consumers nowadays show higher demands for fresh or minimally processed fruits and vegetables, and at the same time potential sources of pathogen infestation are increasing due to the more frequent use of animal manures as fertilizers in organic than in conventional agriculture. On the other hand, a higher antagonistic potential against invading pathogens is implicated from the more diverse microbiota in organic soils. Vegetable-associated outbreaks in Europe are not well documented, and guidelines are missing for reducing risks of pathogen infestation. Thus, a survey on organically grown vegetables has been carried out by the “PathOrganic”...
