Evaluation of Gracilaria gracilis effects on tomato plants: Pipelining the use of a new seaweed extract as biostimulant

Our project aims to develop a pipeline to assess putative biostimulant effects of a novel seaweed extract, produced from the red seaweed Gracilaria gracilis, on Solanum lycopersicum plants. Moreover, we decided to go further and characterize the effects on root/soil microbiota after treatments. We also detected the presence of some interesting bacteria strains in G. gracilis extract, so we included complementary characterization test of these strains as bioinoculant.
