Recent progress in the study of short‐distance (cell‐to‐cell) movement of plant virus, facilitated by ‘movement proteins’, has led to a resurgence of interest in long‐distance virus transport in the phloem. Relatively little is known about phloem‐specific barriers to virus movement or about the form in which virus enters, travels within and exits this tissue. Progress in understanding virus and photoassimilate transport is limited by a paucity of information on the substructure and properties of plasmodesmata at specific interfaces. The direction of virus movement, once it has entered the phloem, can be understood by following photoassimilate translocation, a complex and dynamic process influenced by plant growth, development and vascular topology.
