Antiviral RNAi drives host adaptation to viral infection

Despite extensive understanding of antiviral RNAi in plants, whether and how natural variation in components of RNAi contributes to antiviral immunity remains obscure. Liu . recently identified novel positive and negative antiviral RNAi regulators, supporting RNAi's principal role in the dynamic virus–host coevolution in natural ecosystems.
