摘要： Dryopteris crassirhizomadryocrassin ABBA is a kind of phloroglucinol compound isolated from the whole plants ofDryopteris crassirhizoma. While previous studies have shown that dryocrassin ABBA induces various defence responses in potato tubers, limited information is known about the mechanism of dryocrassin ABBA-induced plant responses. The transcriptome profiles in potato tubers after treatment with dryocrassin ABBA or distilled water were analysed using RNA-Seq. The profiling analysis revealed a total of 37 million clean reads and 3252 differentially expressed genes (DEGs). The data were further confirmed by real-time PCR. The results suggest that dryocrassin ABBA treatment enhances resistance in potatoes, which may be primarily mediated by the salicylic acid (SA) signal pathway, while the jasmonic acid (JA), the ethylene (ET) and the abscisic acid (ABA) signal pathways effectively induce resistance in potatoes. Moreover, the transcripts related to flavonoid metabolism were also up-regulated in potatoes after dryocrassin ABBA treatment, demonstrating that secondary metabolites are related to the constitutive activation of the defence response in dryocrassin ABBA-treated potatoes. These findings reveal that the induced resistance of dryocrassin ABBA is related tomultiple signaling pathways and defence components to enhance host defence responses in potato tubers.
