Membrane Proteins in Plant Viruses

It is clear that MPs play an essential role in the pathogenesis and movement within the plant of many plant viruses. However, studies of the structure and function of such proteins are still in their infancy. Substantial progress may be expected in the next few years, particularly in the area of cell-to-cell movement where viruses are proving useful tools to study the basic processes of macromolecular trafficking between adjacent plant cells.
