dc.description.abstractAlthough previous approaches for plant immune enhancement focused on using chemical or biological agents, recent studies surely suggested that sound vibration (SV) as a physical trigger also could induce plant resistance. Induced resistance is a complicated process containing epigenetic regulation while SV-mediated induced resistance has only been reported based on phenomenological changes, research on epigenetic aspects has been unexplored. Here, we perform integrative analyses of chromatin-immunoprecipitation (ChIP)-seq, microRNA (miRNA)-seq, and RNA-seq regarding the SV-mediated epigenetic changes in Arabidopsis against a root bacterial pathogen, Ralstonia solanacearum. My results revealed that the modification of H3K27me3 largely overlaps with binding sites of upstream of glucosinolate and cytokinin-regulated genes that modulate plant immunity. In addition, out of miRNAs that are differently expressed in SV-exposed plants, miRNA397b up-regulates lignification-related genes leading to cell wall reinforcement. Taken together, my study provides new insight into sound-elicited regulation of secondary metabolites, hormone, and cell wall against R. solanacearum through the epigenetic dynamics with regard to directing transcriptional re-programming.-
