Hijack it, change it: how do plant viruses utilize the host secretory pathway for efficient viral replication and spread?

Abstract: The secretory pathway of eukaryotic cells has an elaborated set of endomembrane compartments involved in the synthesis, modification, and sorting of proteins and lipids. The secretory pathway in plant cells shares many features with that in other eukaryotic cells but also has distinct characteristics important for fundamental cell and developmental processes and for proper immune responses. Recently, there has been evidence that the remodeling of this pathway, and often the formation of viral-induced organelle… Show more

“…In nature, the modification of the plant cell endomembranes seems to be a common feature among most single-stranded positive ss(+)RNA and even some DNA viruses that use viral-induced organelles to support viral replication and spread (Patarroyo et al, 2013). For example comoviridae such as Grapevine fanleaf nepovirus (GFLV) replicates on ER-derived membranes (Ritzenthaler et al, 2002).…”

“…What is not understood is how the virions move from the site of synthesis, the P6 IBs, to the plasmodesmata. For many viruses, models for intracellular movement of the virus have involved the viral MP (Epel, 2009;Harries et al, 2010;Schoelz et al, 2011;Patarroyo et al, 2012;Peña and Heinlein, 2012;Tilsner and Oparka, 2012;Liu and Nelson, 2013). However, in the case of CaMV, Stavolone et al (2005) emphasize that the CaMV MP and virion/VAP complex may travel independently to the plasmodesmata and may first encounter each other at the entrance to the plasmodesmata.…”

“…However, even with the latter model, there is ample evidence that the viral proteins necessary for replication or cell-to-cell movement utilize intracellular trafficking pathways within the cell to become positioned at the plasmodesma. These pathways may involve microfilaments, microtubules, or specific endomembranes that participate in macromolecular transport pathways, or combinations of these elements (Harries et al, 2010;Schoelz et al, 2011;Patarroyo et al, 2012;Peña and Heinlein, 2012;Tilsner and Oparka 2012;Liu and Nelson, 2013).…”

“…The flow of the secretory pathway begins with proteins synthesized at the endoplasmic reticulum (ER) membrane, which are then transported to the Golgi, and finally to the plasma membrane (PM) or extracellular matrix (ECM). Conversely, the flow of the endocytic pathway is from the PM/ECM to the vacuole via endosomes [17]. Bassham uncovered the details of the molecular mechanisms for secretory system function in Arabidopsis thaliana [18].…”
