Mechanisms involved in spatial and temporal mobility of disease patches caused by Rhizoctonia solani in sugar beet field : Induction of antagonists w…
2008
National audience; Rhizoctonia solani AG 2-2 causes damping-off and root rot on sugar beet in patches that are highly mobile both on spatial and temporal scales. They never occur in the same place where they were in the previous season. The aim of the present study was to uncover the mechanisms underlying the dynamics of disease patches. It was observed that soil inoculum potential was higher within diseased patch than in healthy area. However, the dormant pathogen in healthy area was stimulated by addition of buckwheat meal more than that in diseased patch. In addition soil from diseased area was more suppressive towards the disease. We did not observe significant differences in bacterial …

Root growth and development under heat and water stresses: a comparative study determining independent and combined effects in four grain legume spec…
2018
International audience; hanks to their ability to fix atmospheric dinitrogen in symbiosis with soil bacteria, grain legumes provide a sustainable way to ensure food and nutritional security. Unfortunately, these crops are highly susceptible to environmental constraints such as heat or water stresses which leads to fluctuating yields as compared to cereals. In the context of climate change, more frequent episodes of heat stress, concomitant (or not) with water stress are expected. This emphasizes the need to identify key plant traits towards a better yield stability under stressful conditions.
Use of marked strains of pathogenic (FOL8) and protective (FO47) Fusarium oxysporum to visualize their interactions with the tomato root in soil
2008
Several modes of action have been proposed to explain the biocontrol capacity of the Fusarium oxysporum protective strain Fo47, especially competition with the pathogen for root colonization. Confocal microscopy has been used to visualize the interactions between the ransformed strains and the tomato root in soil. A disinfested soil was infested by Fo47 GFP, Fol8 DsRed2, or both fungi together at several concentrations before transplanting tomato seedlings. The general pattern of soil and root colonization was similar for the two fungi, but the saprophytic development of Fo47 was faster than that of the pathogenic strain. Conidia, at the surface of soil particles, germinated as early as 18 …
