To do this, and thanks to the support of the University of Haute-Alsace and the recognition of our work by the wine industry, we were able to hire a bioorganic chemist Research Engineer on September 1<sup>st<\/sup> 2016 and work in close collaboration with the Molecular Innovation and Applications laboratory, which allows us to have a chemical approach that is essential to our thinking. We also hired an Associate Professor specialized in metabolites produced by vine pathogens on September 1<sup>st<\/sup> 2016 and a Laboratory Technician. An Associate Professor from Strasbourg University (HDR to be) also joined us in September 2015, reinforcing our skills on grapevine secondary metabolism.
