Analysis of the gene junctions and complementarities in the IHNV genome. A) Seven identified gene junctions of IHNV in the negative-sense of the genomic RNA are shown. 3'/N, junction of 3'-leader and nucleocapsid gene; N/P, junction of nucleocapsid and phosphoprotein gene; P/M, junction of phosphoprotein and matrix gene; M/G, junction of matrix and glycoprotein gene; G/NV, junction of glycoprotein and non-virion gene; NV/L, junction of non-virion and polymerase gene; L/5'-, junction of polymerase gene and 5' trailer. GE = Gene end; IG = Intergenic di-nucleotide; GS = Gene start. The stop codon of NV ORF is merged with gene end sequence and is shown in red box. B) Complementarities of the 3'- and 5'-ends of the IHNV genome. The first 15 of the 16 nucleotides at the 3'-end are complementary to the 5'-end nucleotides of genomic RNA.
