SNOM signal near plasmonic nanostructures: an analogy with fluorescence decays channels
2008
International audience; Scanning Near-field Optical Microscope (SNOM) is based on local excitations of nanostructures deposited on a substrate (illumination mode). Ideally, the local source behaves like a dipolar emitter so that the SNOM signal is strongly similar to the fluorescence decay rates of an excited molecule that would be located at the SNOM tip position. We present here how the SNOM signal near plasmonic nanostructures can be used to analyze radiative and non-radiative contribution to the fluorescence decay rate.

Medicago species affect the community composition of arbuscular mycorrhizal fungi associated with roots
2007
National audience; The symbiosis between plants and arbuscular mycorrhizal fungi (AMF) is ancient and involves 80% of terrestrial plant families. The symbiotic association between AMF and plants was described to be non specific. However, AMF were reported to influence plant community diversity and productivity. On the other way, the effect of plant genotypes belonging to closely related species on AMF diversity has not been explored so far. The aim of this work was to assess the impact of four different Medicago species, M. laciniata, M. murex, M. polymorpha and M. truncatula cv. Jemalong J5, on the composition of AM fungal community, when cultivated in a silty-thin clay soil (Mas d’Imbert,…
Review of factors influencing the success or failure of biocontrol: technical, industrial and socio-economic perspectives
2010
Communication orale au 11. IOBC-WPRS Meeting of the working group "Biological control of fungal and bacterial plant pathogens". Climate change: challenge or threat to biocontrol?, 2010/06/07-11 ; Graz (AUT).; International audience; Although their role in plant health management is still quite modest, ever increasing expectations are placed on biocontrol agents for the complementation or replacement of pesticide use. Despite decades of research and more than 12,000 scientific papers on biological control of plant diseases, little more than 14 microbe-based commercial products are presently registered for use against diseases in the European Union. Through a review of published scientific li…

Botrytis cinerea strains infecting grapevine and tomato display contrasted repertoires of accessory chromosomes, transposons and small RNAs
2022
Botrytis cinerea stands out for having a wide host range and is qualified as generalist.Nevertheless, recent studies suggest that it actually corresponds to co-existing populationsthat show a certain level of host specialization, as described for the French populations T andG1, specialized on tomato and grapevine, respectively (Mercier et al., 2019, Env. Microbiol.21, 4808–21; Mercier et al., 2021 Phytopathology, 111,2355-66).What are the molecular determinants responsible for such host-specialization? PreviousIllumina sequencing data revealed genes under positive selection encoding cellulases,pectinases and enzymes involved in the oxidative stress response suggesting that theseactivities m…
