Biostimulants promote molecular, biochemical, physiological, and morphological changes in the plant, leading to better adaptation to adverse conditions and increasing growth and yields. This work evaluated how the combined application of humic acids and a synthetic bacterial consortium (sym) or humic acids (HA) plus sym suspension and peptidogalactomannan (pGM) of a cell wall fungus affected some defense-related and phytohormone gene expression profiles in passion fruit plants under greenhouse and field conditions. Both treatments induced the expression of all defense-related genes evaluated 24 h after treatment, as shown by RT?qPCR assays. Interestingly, both auxin-responsive protein SAUR20 and gibberellin 2-beta dioxygenase 2 mRNAs were observed to be upregulated 16 weeks after the treatments, which was associated with an increase in shoot and root biomass and the number of leaves. These results may explain how these treatments can improve the plant growth reported in the literature and elucidate the putative effect on plant defense mechanisms, which can induce plants to have stronger responses against biotic stress coupled with growth traits. Our results suggest that disseminating these technologies may improve passion fruit productivity in an ecologically friendly manner.  aHumic acids  aBacterial consortia  aBiostimulation  aPeptidogalactomannan1 aMONTEBIANCO, C. de B.1 aOLIVARES.
