摘      要：Compared with the use of monocultures in the field,cultivation of medicinal herbs in forests is an effective strategy to alleviate *** interactions between herbs and trees play an important role in disease suppression in *** evaluated the ability of leachates from needles of Pinus armandii to induce resistance in Panax notoginseng leaves,identified the components via gas chromatography-mass spectrometry(GC-MS),and then deciphered the mechanism of 2,3-Butanediol as the main component in the leachates responsible for resistance induction via RNA sequencing(RNA-seq).Prespraying leachates and 2,3-Butanediol onto leaves could induce the resistance of *** to Alternaria *** RNA-seq results showed that prespraying 2,3-Butanediol onto leaves with or without *** infection upregulated the expression of large number of genes,many of which are involved in transcription factor activity and the mitogen-activated protein kinase(MAPK) signaling ***,2,3-Butanediol spraying resulted in jasmonic acid(JA)-mediated induced systemic resistance(ISR) by activating MYC2 and ***,2,3-Butanediol induced systemic acquired resistance(SAR) by upregulating pattern-triggered immunity(PTI)-and effector-triggered immunity(ETI)-related genes and activated camalexin biosynthesis through activation of ***,2,3-Butanediol from the leachates of pine needles could activate the resistance of *** to leaf disease infection through ISR,SAR and camalexin ***,2,3-Butanediol is worth developing as a chemical inducer for agricultural production.
