Symptoms of Cucumber mosaic virus (CMV) infection and accumulation of viral RNA in inoculated leaves of NC82 and Taiyan8. (A) Symptoms of CMV infection on inoculated leaves of two cultivars at 5 days post inoculation (dpi). Hypersensitive response like necrotic lesions on the inoculated Taiyan8 leaves at 5 dpi are indicated by the red cycles. (B) Semiquantitative RT-PCR detection results of inoculated leaves. The upper and lower lane indicates the amplification results with CMV coat protein gene and NtEF1α specific primers, respectively. M, DNA molecular weight marker; 1–4, mock-inoculated, CMV-inoculated at 1 dpi, CMV-inoculated at 3 dpi, and CMV-inoculated at 5 dpi of NC82 leaf; 5–8, mock-inoculated, CMV-inoculated at 1 dpi, CMV-inoculated at 3 dpi, and CMV-inoculated at 5 dpi of Taiyan8 leaf. The full-length gels are presented in Supplementary Fig. 2A,B. (C) Expression levels (FPKM) of CMV-associated genes in inoculated leaves of NC82 (NB) and Taiyan8 (TB) according to RNA-sequencing data. Cluster-14949.79513 is predicted to encode the CMV strain CTL segment RNA1; cluster-14949.77700 is predicted to encode the CMV isolate RP10 segment RNA2; cluster-14949.80413 is predicted to encode the CMV 3a gene for movement protein and the cp gene for coat protein.
