Expression Pattern of RNA Interference Genes During Drought Stress and MDMV Infection in Maize

Abstract When stress factors trigger transcriptional and metabolic changes, RNA interference (RNAi) is associated with gene expression regulation at the post-transcriptional levels. RDR, DCL AGO proteins contribute to these silencing processes during reactions plant development. An entire revision of maize genes was carried out prior experiments. In this study, transcript changes a total 4 ZmRDR , 5 ZmDCL 17 ZmAGO were analysed in either drought or MDMV infection, without salicylic acid pre-treatment siRNA pre-treatment, respectively. The profiles showed early, middle late activity genes. Drought caused major profiles, indicating that there various steps response regulation. Moreover, insights gained into fine-tuning mechanisms SA case infection less diverse trends observed, which mainly focused on antiviral defence. However, treatment exogenous seems be an appropriate tool for targeted influencing RNAi, especially These results represent first contribution relationship between RNAi salicylate signalling viral siRNA-triggered defence maize.
