Movement Profiles: A Tool for Quantitative Analysis of Cell-to-Cell Movement of Plant Viral Movement Proteins

open access: closed, 2008
Movement proteins (MPs) are virally encoded factors that mediate transport of viral nucleic acid between plant cells. Many MPs are able to move between cells themselves. This feature serves as the basis for evaluation of the transport activity of individual MPs.

A dual-function movement protein regulates viral replication suppression and movement facilitation in plant viral infections

open access: closedPlant Physiology
Abstract Viral replication and intracellular movement are essential and interdependent steps during plant viral infections. Mechanistic insights into each step have been established, but the regulatory interplay between these processes and their underlying molecular mechanisms remains poorly understood.

Evidence for expression level‐dependent modulation of carbohydrate status and viral resistance by the potato leafroll virus movement protein in transgenic tobacco plants

open access: closedThe Plant Journal, 2001
SummaryHigh‐level constitutive expression of the cell‐to‐cell movement protein from the phloem‐restricted potato leafroll virus (PLRV‐MP17) in transgenic tobacco plants leads to growth retardation and severe phenotypic changes of source leaves paralleled by a drastic accumulation of soluble sugars and starch (Herbers et al., 1997).

Interaction of Movement Proteins with Host Factors, Mechanism of Viral Host Cell Manipulation and Influence of MPs on Plant Growth and Development

open access: closed, 2016
Even more than 100 years after Eduard Tangl first described plasmodesmata (PD) as “open communications” between protoplasts of endosperm cells (Carr 1976), the components of plasmodesmata as well as plasmodesmata-located proteins still remain enigmatic. Considering the fact, that this system is also co-opted by various plant viruses to enable the viral

Plant Protein-Mediated Inhibition of Virus Cell-to-Cell Movement: Far-Western Screening and Biological Analysis of a Plant Protein Interacting with a Viral Movement Protein

2019
Cell-to-cell movement via plasmodesmata is a crucial step for plant RNA viruses to determine their host ranges. Many viruses including Tomato mosaic virus (ToMV) encode one or more movement proteins (MPs) that are indispensable for cell-to-cell movement.
