Abstract

The complete genomic sequence of Helicoverpa armigera nucleopolyhedrovirus from Australia, HearNPV-Au, was determined and analyzed. The HearNPV-Au genome was 130,992 bp in size with a G + C content of 39 mol% and contained 134 predicted open reading frames (ORFs) consisting of more than 150 nucleotides. HearNPV-Au shared 94 ORFs with AcMNPV, HearSNPV-G4 and SeMNPV, and was most closely related to HearSNPV-G4. The nucleotide sequence identity between HearNPV-Au and HearSNPV-G4 genome was 99 %. The major differences were found in homologous regions (hrs) and baculovirus repeat ORFs (bro) genes. Five hrs and two bro genes were identified in the HearNPV-Au genome. All of the 134 ORFs identified in HearNPV-Au were also found in HearSNPV-G4, except the homologue of ORF59 (bro) in HearSNPV-G4. The sequence data strongly suggested that HearNPV-Au and HearSNPV-G4 belong to the same virus species.
