Viral movement proteins Definition:
Plant viruses produce viral movement proteins that cause the plasmodesmata to dilate, enabling the viral RNA to pass between cells.

Viral movement proteins Notes:
A movement protein is a non-structural protein which is encoded by some plant viruses to allow their movement from one infected cell to neighboring cells. Many, if not all, plant viruses encode a movement protein, and some express more than one. The movement protein of tobacco mosaic virus (TMV) has been most extensively studied. These proteins dedicated to enlarging the pore size of plasmodesmata and actively transporting the viral nucleic acid into the adjacent cell, thereby allowing local and systemic spread of viruses in plants.
