The Tobamovirus Turnip Vein Clearing Virus 30-Kilodalton Movement Protein Localizes to Novel Nuclear Filaments To Enhance Virus Infection

Plant viruses overcome the barrier of the plant cell wall by encoding cell-to-cell movement proteins (MPs), which direct newly replicated viral genomes to, and across, the wall. The paradigm for how a single MP regulates and coordinates these activities is the Tobacco mosaic virus (TMV) 30-kDa protein (MP TMV ). Detailed studies demonstrate that TMV multiplies exclusively in the cytoplasm and have documented associations of MP TMV with...
