AI Article Synopsis
- The genome of the Helicoverpa armigera nucleopolyhedrovirus from Australia, known as HearNPV-Au, is 130,992 base pairs long and has a G + C content of 39 mol%, containing 134 predicted open reading frames (ORFs).
- HearNPV-Au shares 94 ORFs with other related viruses, including AcMNPV and HearSNPV-G4, and has a 99% nucleotide sequence identity with HearSNPV-G4, suggesting a close genetic relationship.
- Key differences were found in specific gene regions, with five homologous regions and two baculovirus repeat ORF genes identified in HearNPV-Au, indicating that the two
Article 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.
