Cloned poliovirus complementary DNA is infectious in mammalian cells

V R Racaniello et al. Science. 1981.

Abstract

A complete, cloned complementary DNA copy of the RNA genome of poliovirus was constructed in the Pst I site of the bacterial plasmid pBR322. Cultured mammalian cells transfected with this hybrid plasmid produced infectious poliovirus. Cells transfected with a plasmid which lacked the first 115 bases of the poliovirus genome did not produce virus.
