Interplay between potato virus X and RNA granules in Nicotiana benthamiana

Cytoplasmic RNA granules consist of microscopic agglomerates of mRNAs and proteins and occur when the translation is reversibly and temporally halted (stress granules, SGs) or mRNAs are targeted for decapping (processing bodies, PBs). The induction of RNA granules formation by virus infection is a common feature of mammalian cells. However, plant-virus systems still remain poorly characterized. In this work, the SG marker AtUBP1b was expressed...
