Subcellular, sequence-specifi c detection of RNA in vivo is a powerful tool to study the macromolecular transport that occurs through plasmodesmata. The RNA-binding domain of Pumilio proteins can be engineered to bind RNA sequences of choice and fused to fl uorescent proteins for RNA imaging. This chapter describes the construction of a Pumilio-based imaging system to track the RNA of Tobacco mosaic virus in vivo, and practical aspects of RNA live-cell imaging.
