To establish a productive infection in new host species, viruses must overcome barriers mediated by diverse and rapidly evolving host restriction factors such as protein kinase R (PKR). To model the p
Poxviruses are large DNA viruses that rapidly adapt to hosts despite a relatively low mutation rate. One mechanism for adaptive evolution is through transient copy number variation described as ‘gene
Viruses continually adapt to evade host immune defenses. To understand how poxviruses adapt to strong selective pressure imposed by innate immune detection pathways, we performed experimental evolutio
