摘要 As sessile organisms,plants encounter diverse invasions from pathogens including viruses.To survive and thrive,plants have evolved multilayered defense mechanisms to combat virus infection.RNAi,also known as RNA silencing,is an across-kingdom innate immunity and gene regulatory machinery.Molecular framework and crucial roles of RNAi in antiviral defense have been well-characterized.However,it is largely unknown that how RNAi is transcriptionally regulated to initiate,maintain and enhance cellular silencing under normal or stress conditions.Recently,insights into the transcriptional and post-transcriptional regulation of RNAi-related genes in different physiological processes have been emerging.In this review,we integrate these new findings to provide updated views on how plants modulate RNAi machinery at the(post-)transcriptional level to respond to virus infection.
