摘要: The brown planthopper (BPH) is the most devastating insect pest of rice. rice gene BPH15 confers resistance to BPH. MicroRNAs (miRNAs) regulate a spectrum development and defense response processes in plants. In this study, we analyzed six miRNA profiles introgression line (P15) susceptible recipient (PC) at three time points (0 h, 6 h 48 h) after BPH attack, identified 464 known miRNAs 183 potential novel miRNAs. Before feeding, 23 differentially expressed P15 PC. We speculated that resistant plant priming state by regulation After 104 were found be (68 P15-6/P15-0, 36 P15-48/P15-0), 80 PC (32 PC-6/PC-0, 48 PC-48/PC-0), which illustrated expression activated upon attack. These different pathways contribute basal specific Our study provides additional data for scientists further explore mechanism against attack find way efficient control.
