Fig 2. Vs and Hypr chimaeric viruses.
A) The polyproteins, with individual proteins of Hypr virus (grey bars) and Vs virus (white bars) are flanked with 3`UTR (thick and thin lines for Hypr and Vs respectively). B) Schematic representation of the 3`UTRs., Numbers specify nucleotide positions in 3’UTRs following the stop codon. Internal deletions present in the Hypr and Vs genomes are identified by the numbers corresponding to those of the Hypr-long 3’UTR. Intermediate plasmids, constructed to recover Hypr, Vs and chimaeric Hypr/Vs infectious virus, are presented in S1 Fig.
