ABSTRACT
Southern rice black-streaked dwarf virus (SRBSDV), a genus Fijivirus of the family Reoviridae, could result in the significant crop losses because being short of an effective controlling measures. Cytosinpeptidemycin, a microbial pesticides developed by China, displayed a wide antiviral activity against many plant viruses. However, its underlying mechanism remains unclear. In this study, a total of 2321 proteins were identified using label-free proteomics technology. Compared with the treatment of SRBSDV-infected rice, 84 and 207 proteins were detected to be up-regulated and only presented in treatment group of SDBSDV-infected rice pre-treated by Cytosinpeptidemycin, which were partially enriched to stress and defense response, such as pathogenesis-related protein 5 (PR-5), pathogenesis-related protein 10 (PR-10) and heat shock protein (Hsp protein). Meanwhile, the real-time quantitative PCR (RT-qPCR) showed that Cytosinpeptidemycin could also up-regulate some resistance genes, and these results indicated a similar trends with the data of the label-free proteomics. Moreover, Cytosinpeptidemycin could enhance the defense enzymatic activities of peroxidase (POD), superoxide dismutase (SOD), and catalase (CAT). These data offer a more comprehensive view about the response of SRBSDV-infected rice triggered by Cytosinpeptidemycin in the level of the proteome, mRNA and enzymatic activity.
