Genome PRRSV

The complete genome sequence of the PRRS virus was documented in 1993. It is about 15 kb in size and contains 7 Open Reading Frames (ORFs). ORFs 1a and 1b make up about 80% of the genome and code for the RNA-dependent RNA polymerase. The 6 smaller ORFs, 2-7, encode structural proteins associated with the virion.
