摘　　要：Prior exposure to microbial-associated molecular patterns or specific chemical compounds can promote plants into a primed state with stronger defence responses.β-aminobutyric acid(BABA)is an endogenous stress metabolite that induces resistance protecting various plants towards diverse stresses.In this study,by integrating BABA-induced changes in selected metabolites with transcriptome and proteome data,we generated a global map of the molecular processes operating in BABA-induced resistance(BABA-IR)in tomato.BABA significantly restricts the growth of the pathogens Oidium neolycopersici and Phytophthora parasitica but not Botrytis cinerea.A cluster analysis of the upregulated processes showed that BABA acts mainly as a stress factor in tomato.The main factor distinguishing BABA-IR from other stress conditions was the extensive induction of signaling and perception machinery playing a key role in effective resistance against pathogens.Interestingly,the signalling processes and immune response activated during BABA-IR in tomato differed from those in Arabidopsis with substantial enrichment of genes associated with jasmonic acid(JA)and ethylene(ET)signalling and no change in Asp levels.Our results revealed key differences between the effect of BABA on tomato and other model plants studied until now.Surprisingly,salicylic acid(SA)is not involved in BABA downstream signalization whereas ET and JA play a crucial role.
