The 5'-3' exoribonucleases (Xrns) play key roles in degradation and processing pathways of several classes of RNAs including mRNA, rRNA, miRNA and other small RNAs. Recent work revealed that the cytoplasmic Xrn (Xrn1p in yeast and Xrn4 in plants) affected the stability of the viral RNA of tombusviruses in yeast and plants, which indicates that the cytoplasmic Xrn might be involved in plant defense against virus by degrading viral RNA. Here, we demonstrated that silencing of Nicotiana benthamiana cytoplasmic Xrn4 facilitated both local and systemic infection of Tobacco mosaic virus (TMV) in N. benthamiana. The results support the suggestion that cytoplasmic Xrn4 participates in the viral defense system of plants.
