Abstract

Plant development depends on the intercellular transport of macromolecules through gatable channels in the cell wall known as plasmodesmata (PD). Plant viruses exploit this intercellular trafficking pathway to move cell-to-cell and to cause systemic infection. Dependent on viral species, movement through PD can occur in virion or non-virion form and by different mechanisms for targeting and modification of the pore. These mechanisms are supported by viral movement proteins and by other virus-encoded factors that interact among themselves and with plant cellular components to facilitate virus movement in a coordinated and regulated fashion. This chapter provides an overview about current knowledge in virus cell-to-cell movement with the aim to extract principal mechanisms playing a role in intercellular transport.
