Role of Intergenic Sequences in Newcastle Disease Virus RNA Transcription and Pathogenesis

Abstract excerpt

Newcastle disease virus (NDV), a member of the family Paramyxoviridae, has a nonsegmented negative-sense RNA genome consisting of six genes (3'-NP-P-M-F-HN-L-5'). The first three 3'-end intergenic sequences (IGSs) are single nucleotides (nt), whereas the F-HN and HN-L IGSs are 31 and 47 nt, respectively. To investigate the role of IGS length in NDV transcription and pathogenesis, we recovered viable viruses...
