ABSTRACT A hybrid virus (CMVcymMP) constructed by replacing the movement protein (MP) of cucumber mosaic cucumovirus (CMV) with that of cymbidium ringspot tombusvirus (CymRSV) was viable and could efficiently spread both cell to cell and long distance in host plants. The hybrid virus was able to move cell to cell in the absence of functional CP, whereas CP-deficient CMV was restricted to single inoculated cells. In several Chenopodium and Nicotiana species, the symptom phenotype of the hybrid virus infection was clearly determined by the foreign MP gene. In Nicotiana debneyi and Nicotiana tabacum cv. Xanthi, the hybrid virus could move systemically, contrary to CymRSV.

Symptom Recovery

Plants have evolved multiple mechanisms to respond to viral infection. These responses have been studied in detail at the level of host immune response and antiviral RNA silencing (RNAi). However, the possibility of epigenetic reprogramming has not been thoroughly investigated. Here, we identified the role of DNA methylation during viral infection and performed reduced representation bisulfite sequencing (RRBS) on tissues of Cucumber mosaic virus (CMV)-infected Nicotiana tabacum at various developmental stages. Differential methylated regions are enriched with CHH sequence contexts, 80% of which are located on the gene body to regulate gene expression in a temporal style. The methylated genes depressed by methyltransferase inhibition largely overlapped with methylated genes in response to viral invasion. Activation in the argonaute protein and depression in methyl donor synthase revealed the important role of dynamic methylation changes in modulating viral clearance and resistance signaling. Methylation-expression relationships were found to be required for the immune response and cellular components are necessary for the proper defense response to infection and symptom recovery.

Resistance Evaluation of Chillipepper Cultivars for Cucumber Mosaic Virus and Chilli Veinal Mottle Virus.  The use of resistance culivars is an important strategy for management of virus infection in chillipepper. A research was undergone to study the effect of single and mix infection of CMV and ChiVMV on the disease incidence and on the growth and yield of nine chillipepper cultivars, i.e. Cilibangi 4, Cilibangi 5, Cilibangi 6, Helem, Jatilaba, Tit Bulat, Tit Segitiga, Tit Super and Tampar. Mechanical inoculation was conducted to transmit the virus. Infection of the virus was then confirmed with DAS-ELISA.  In general, inoculated chillipepper cultivars developed similar symptoms, i.e. mosaic type for CMV and mottle type for ChiVMV.  More severe symptom was not always observed from mix infection of CMV and ChiVMV. Disease incidence occurred in the range of 16.67 – 86.0% and this caused 18.3 – 98.6% yield loss.  Based on symptom expression, ELISA result, and reduction on yield, it can be concluded that all chillipepper cultivars used in this study could not hold up the virus infection. However, several cultivars showed tolerance response :  Jatilaba, Tit Super, and Tampar for CMV; Cilibangi 4 for ChiVMV; Tit Super for mix infection; and Cilibangi 5 for CMV, ChiVMV, and mix infection.  Further evaluation and investigation involving different chillipepper cultivars should be conducted.
