Towards microbiota-based disease management: analysis of grapevine microbiota in plots with contrasted levels of downy mildew infection
Vers une gestion des maladies basée sur le microbiote : analyse du microbiote de la vigne dans des parcelles présentant des niveaux contrastés d'infection par le mildiou
Résumé
Vineyards harbor a myriad of microorganisms that interact with each other and with the grapevines. Some microorganisms are plant pathogens, such as the oomycete Plasmopara viticola that causes grapevine downy mildew. Others, such as plant growth promoting bacteria and disease biocontrol agents, have a positive influence on vine health. The present study aims to (1) investigate whether vine-based culture media increase the cultivability of the grapevine microbiota, in comparison to standard culture media and (2) identify and isolate bacterial taxa naturally present in grapevine leaves and significantly more abundant in plots showing low susceptibility to downy mildew.
