Identification et suivi par spectrométrie de masse de composés impliqués dans la défense des feuilles de vigne caractérisées pour leur niveau de résistance au mildiou

Abstract : Downy mildew, caused by the Plasmopara viticola pathogen, is a fungal disease which can induce serious harvest damages. To avoid these losses, it is necessary to use phytosanitary treatments. In addition to their financial cost, winegrower’s health issues and the environment protection cannot be ignored. However, all grapevine varieties do not present the same sensitivity to the pathogen. Indeed, despite of poor organoleptic qualities, American varieties are resistant to this disease. Combining them with European species by varietal crossing may be a viable alternative to these treatments. However, to lead efficiently these cross breeding programs, it is necessary to know more about the relationship "host-pathogen". In this context, analysis by mass spectrometry has been used under different aspects
