Plant-beneficial microbes are known to provide multifaceted traits to the plant health. Among
them, Bacillus species are commonly detected members of the plant holobiont which have been
described as stimulators of seed germination, plant growth and the defense against
phytopathogens. In this work we describe, with the utilization of untargeted metabolomics and
bioinformatic tools as GNPS, MolNetEnhancer and MZmine, the different metabolomic patterns
found according to the elderly of the leaves. In addition, we compare the metabolomic profile of
plants 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 each
bacterium against abiotic stresses.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tec
