Multiple MicroRNAs are Involved in Regulating Peanut (Arachis hypogaea L.) Resistance to Sclerotium rolfsii at the Early Stage

Stem rot, caused by soilborne pathogen Sclerotium rolfsii, is one of the most destructive diseases peanut (Arachis hypogaea L.) worldwide. Although microRNAs (miRNAs) are indispensable regulators for plant defense, miRNA species have not been explored immunity against rolfsii. Here, we report a comparative analysis durably resistant variety Rizhaohua-1 (Rzh) and susceptible Jitian-1 (JT) in response to infection We identified group known novel miRNAs that were differentially expressed upon S. rolfsii infection. The predicted target genes included receptor kinases, transcription factors, involved production transport metabolites. In this study, shown regulate broad range respond pathogen, eventually establish systemic defense network combat disease.
