SEAWINES PROJECT PROPOSES AN INTERDISCIPLINARY APPROACH FOR EVALUATING THE USE OF TWO SEAWEED EXTRACTS IN THE VINEYARD AS AN ALTERNATIVE AND ENVIRONMENTALLY FRIENDLY SUSTAINABLE TOOL TO IMPROVE GRAPEVINE RESISTANCE TO DOWNY AND POWDERY MILDEW, WITHOUT IMPAIRING, OR EVEN IMPROVING, GRAPE AND WINE QUALITY AND REDUCING THE SOCIO-ECONOMIC AND ENVIRONMENTAL IMPACT OF THE SEAWEEDS ON THE COAST, CONTRIBUTING IN THIS MANNER TO CIRCULAR ECONOMY.THE UNDERSTANDING OF SEAWEED INFLUENCE ON PLANT PHYSIOLOGY AND ON GRAPEVINE ASSOCIATED INDIGENOUS MICROBIAL COMMUNITIES IS SCARCE, WHICH IS KEY TO ELUCIDATE GRAPEVINES TOLERANCE/SUSCEPTIBILITY TO THE DISEASES. AMONG OTHER MODIFICATIONS, AN ENHANCEMENT IN FOLIAR DEVELOPMENT AND CHLOROPHYLL CONCENTRATIONS HAVE BEEN RECORDED AS INFLUENCED BY SEAWEED EXTRACT IMPROVING VEGETATIVE GROWTH. IN ADDITION, DIFFERENCES IN THE FOLIAR AND GRAPE MICROBIAL COMMUNITY AS A FUNCTION OF CHEMICAL FUNGICIDES AND ALGAE EXTRACT, SUCH AS LAMINARIN, HAVE BEEN PREVIOUSLY DESCRIBED, MODIFYING THE RATIO BETWEEN PATHOGENS AND BENEFICIAL MICROORGANISMS. INTERESTINGLY, SULPHUR AND COPPER BASED FUNGICIDES HAVE SHOWN TO DECREASE THE BIODIVERSITY OF YEASTS AND FUNGI IN RESULTANT FERMENTATIONS, AND HENCE, PROVE THAT THE MICROBIAL DIFFERENCES AT THE VINEYARD LEVEL COULD BE MAINTAINED THROUGH THE WINEMAKING PROCESS. HOWEVER, THE IMPACT OF SEAWEED PRODUCTS ON THE GRAPES QUALITY AND FERMENTATION PROCESS IS VERY LIMITED, BUT FUNDAMENTAL IN ORDER TO MANIPULATE IN A SUSTAINABLE AND ENVIRONMENTALLY FRIENDLY WAY THIS ECOSYSTEM IN FAVOR OF VITICULTURISTS AND CONSUMERS. CONSIDERING ALL THE ABOVE, WE PROPOSE TO EVALUATE THE EFFICACY OF SEAWEED IN VITICULTURE USING A HOLISTIC APPROACH, INTEGRATING DIFFERENT SCIENTIFIC DISCIPLINES TO ACQUIRE INSIGHTS ABOUT THE RESPONSE OF THE VINE HOLOBIONT TO SEAWEED APPLICATIONS (COMPRISING THE GRAPEVINE AS A WHOLE TOGETHER WITH ITS ASSOCIATED MICROBIOTA) ON THE WHOLE CHAIN: GREENHOUSE, FIELD AND WINEMAKING.WITHIN SEAWINES COORDINATED PROJECT, SUBPROJECT 2 WILL SEARCH FOR THE OPTIMAL DOSE AND APPLICATION FREQUENCY OF ULVA OHNOI AND RUGULOPTERYX OKAMURAE SEAWEEDS, STUDYING 1) THEIR IMPACT ON THE DISEASE INCIDENCE/SEVERITY OF POWDERY AND DOWNEY MILDEW), 2) THE PHYSIOLOGICAL CHANGES PROVOKED IN THE GRAPEVINE, AND 3) THE SHIFTS ON MICROBIAL DIVERSITY AND COMMUNITY COMPOSITION IN GRAPE AND WINE. THIS DATA WILL BE INTEGRATED WITH THE PLANT MOLECULAR RESPONSE TO SEAWEED, AND GRAPE AND WINE CHEMICAL COMPOSITION RESULTS OBTAINED IN SUBPROJECT 1. IN ALL, THE COLLABORATIVE FRAMEWORK OF BOTH SUBPROJECTS WILL PROVIDE UNPARALLELED INSIGHTS INTO THE RESPONSE AND INTERACTIONS OCCURRING AT THE LEVEL OF THE FULL SYSTEM- NAMELY BETWEEN THE PATHOGEN, GRAPEVINE MICROORGANISMS, PLANT, AND ULTIMATELY WINE.THE PROJECT IS SCIENTIFICALLY AND SOCIO-ECONOMICALLY ATTRACTIVE, OFFERING AN INNOVATIVE APPROACH AND A HIGHLY COLLABORATIVE NETWORK TOWARDS THE TESTING OF AN ALTERNATIVE PLANT PROTECTION STRATEGY THAT WOULD REDUCE CHEMICAL ACCUMULATION IN VITICULTURE. WE WILL GENERATE A CATALOGUE OF HOST-MICROBIOTA INTERACTIONS RELEVANT FOR BASIC RESEARCH, AS WELL AS FOR THE INDUSTRY, AS IT OPENS THE POSSIBILITY FOR FURTHER IDENTIFICATION AND DEVELOPMENT OF BIOLOGICAL CONTROLS AGAINST FUNGAL DISEASES. FURTHERMORE, SEAWINES FOSTERS THE STUDY OF THE BIODIVERSITY ASSOCIATED TO THE GRAPEVINE, WHICH IS KEY FOR IMPROVING ITS PRODUCTIVITY AND RESISTANCE, BUT ALSO, TO CONSERVE AND PROTECT NATURAL DIVERSITY AND SPECIES RICHNESS VITAL TO SAFEGUARD LIFE ACROALGAS\VINO\UVA\MICROBIOTA\OMICAS\NGS\FISIOLOGIA\SOSTENIBILIDAD\REDUCCION QUIMICOS\FITOPATOGENOS
