In recent years there have been significant advances in our understanding of the ER stress responses in plants that are associated with virus infection, as well as bacterial and fungal diseases. In plants, ER stress induced by virus infection includes several signaling pathways that include the unfolded protein response (UPR) to promote the expression of chaperone proteins for proper protein folding. Understanding how facets of ER stress signaling broadly engage in pathogen responses, as well as those that are specific to virus infection is important to distinguishing features essential for broad cellular defenses and processes that may be specifically linked to viral infectivity and disease.
