Plant Virus Movement

Plant virus movement is the process of the spread of virus genetic material from the initially infected cells to the rest of the plant. There are several distinct stages including intracellular movement from sites of virus replication out of the initially infected cell, cell-to-cell trafficking through plasmodesmata (plant-specific intercellular membranous channels) and long-distance movement between organs through the phloem (the specialized vascular system used by plants for the transport of assimilates and macromolecules).

Keywords: movement proteins; systemic infection; ribonucleoprotein particles; RNA binding; triple gene block; tubules
