RT Conference Proceedings T1 Seed treatments with Bacillus species induce a beneficial metabolic reprogramming in melon plants A1 Molina-Santiago, Carlos A1 Carrégalo, Luisa A1 Pineda, Mónica A1 Berlanga-Clavero, María Victoria A1 Dorrestein, Pieter A1 De-Vicente-Moreno, Antonio A1 Barón, Matilde A1 Romero-Hinojosa, Diego Francisco K1 Relaciones planta-microbio AB Plant-beneficial microbes are known to provide multifaceted traits to the plant health. Amongthem, Bacillus species are commonly detected members of the plant holobiont which have beendescribed as stimulators of seed germination, plant growth and the defense againstphytopathogens. In this work we describe, with the utilization of untargeted metabolomics andbioinformatic tools as GNPS, MolNetEnhancer and MZmine, the different metabolomic patternsfound according to the elderly of the leaves. In addition, we compare the metabolomic profile ofplants emerged from seeds bacterized with B. subtilis and B. velezensis identifying tryptophan,a chlorophyll A analog and flavonoids as key metabolites in the specific response of eachbacterium against abiotic stresses.
