Structural flexibility of the SARS-CoV-2 genome relevant to variation, replication, pathogenicity, and immune evasion.
Abstract
The SARS-CoV-2 pandemic continues to be driven by viral variants. Most research has focused on structural proteins and on site-specific mutations. Here, we describe recombination events involving genomic terminal sequences in SARS-CoV-2 and related viruses leading to structural rearrangements in terminal and coding regions and discuss their potential contributions to viral variation, replication, pathogenicity, and immune evasion.
