Cucumber mosaic virus (CMV) is a plant virus with one of the largest host ranges, the widest distribution, and economic importance, and ningnanmycin (NNM) is a commercial antiviral agent. Studies have shown that NNM induces and promotes pathogenesis-related proteins in tobacco mosaic virus-inoculated tobacco. In the present study, the defense enzymes and the biochemical factors of CMV-inoculated tobacco treated with NNM were measured. The biochemical factors of CMV-inoculated tobacco leaves treated with NNM were analyzed. Results showed that the phenylalanine ammonia-lyase, peroxidase, polypheuoloxidase, and superoxide in the CMV-inoculated tobacco leaves treated with NNM were higher than those in non-treated tobacco leaves. Furthermore, NNM activated the oxidation-reduction process, metabolic process, and oxidoreductase activity in the CMV-infected tobacco.
