GAPDH-A Recruits a Plant Virus Movement Protein to Cortical Virus Replication Complexes to Facilitate Viral Cell-to-Cell Movement
The formation of virus movement protein (MP)-containing punctate structures on the cortical endoplasmic reticulum is required for efficient intercellular movement of Red clover necrotic mosaic virus (RCNMV), a bipartite positive-strand RNA plant virus. We found that these cortical punctate structures constitute a viral replication complex (VRC) in addition to the previously reported aggregate s...
متن کاملThe Plant Cellular Systems for Plant Virus Movement
Plasmodesmata (PDs) are specialized intercellular channels that facilitate the exchange of various molecules, including sugars, ribonucleoprotein complexes, transcription factors, and mRNA. Their diameters, estimated to be 2.5 nm in the neck region, are too small to transfer viruses or viral genomes. Tobacco mosaic virus and Potexviruses are the most extensively studied viruses. In viruses, the...
متن کاملThe cell biology of Tobacco mosaic virus replication and movement
Successful systemic infection of a plant by Tobacco mosaic virus (TMV) requires three processes that repeat over time: initial establishment and accumulation in invaded cells, intercellular movement, and systemic transport. Accumulation and intercellular movement of TMV necessarily involves intracellular transport by complexes containing virus and host proteins and virus RNA during a dynamic pr...
متن کاملCellular chaperones and folding enzymes are vital contributors to membrane bound replication and movement complexes during plant RNA virus infection
Cellular chaperones and folding enzymes play central roles in the formation of positive-strand and negative-strand RNA virus infection. This article examines the key cellular chaperones and discusses evidence that these factors are diverted from their cellular functions to play alternative roles in virus infection. For most chaperones discussed, their primary role in the cell is to ensure prote...
متن کاملMembrane rafts and virus movement in plant cells.
Lipid rafts are liquid-ordered subdomains within cell membranes that are hypothesized to be highly dynamic assemblies that play important roles in signal transduction and membrane trafficking in the plasma membrane of both animal and plant cells (reviewed in Bhat and Panstruga, 2005; Brown, 2006). However, solid evidence of their importance and functions remains sketchy (Shaw, 2006). Studies in...
