The Plant Cell
Animals and plants evolved systems to permit non-cell-autonomous trafficking of RNA, whereas DNA plays a cell-autonomous role. In plants, plasmodesmata serve as the conduit for this phenomenon, and viruses have evolved to use this pathway for the spread of infectious nucleic acids. In this study, a plant DNA virus was used to explore the constraints imposed on the movement of DNA through this endogenous RNA trafficking pathway. The combined properties of the geminivirusencoded movement proteindoi:10.1105/tpc.015057 pmid:14555695 pmcid:PMC280562 fatcat:63nwyindofgydgdrtpzj5qacem
