While many protein-protein interactions have been reported, only a fraction are essential for potyviral infection. Accumulating evidence demonstrates that potyviral infection processes are interconnected. For instance, the interaction between the eukaryotic initiation factor 4E (eIF4E) and viral protein genome-linked (VPg) is crucial for both viral translation and protecting viral RNA (vRNA). Additionally, recent evidence for open reading frames on the reverse-sense vRNA and for nonequimolar expression of viral proteins has challenged the previous polyprotein expression model. These discoveries will surely reveal more about the potyviral protein interactome.

This demise of phage therapy has traditionally been attributed to the superiority of antibiotics, discovered and first used during the war years, but this explanation is complicated by the fact that phage therapy outside the United States has had a longer and more successful life, especially in the countries of Eastern Europe. This review considers another, probably synergetic factor that was specific to the medical uses of phage in the United States: the geopolitical climate fostered by the Cold War reaction against Soviet science and its associated specter, socialized medicine.

Multiple capsid interactions with viral and host proteins have been characterized using viral mutants and assays that reconstitute key stages of the infection cycle.

Also, the diversity and ecological characteristics of vertebrate hosts might serve as protective factors. Moreover, although forest areas remained well preserved until recently, current brutal, sudden, and large-scale clear cuts through the forest have resulted in nearly no ecotones, which are essential for creating an adaptive gradient of microbes, hosts, and vectors.
