“…The EppoNPV genome has been sequenced , a number of virulence genes characterised, (Caradoc-Davies et al, 2001;Maguire et al, 2000;Ward et al, 2002;Young et al, 2005) and microarray analysis performed Jordan et al, 2008) to identify genes that are regulated by the virus-host interaction (Gatehouse et al, , 2009. A major limitation when analysing viral gene function and host cell responses is the inability to propagate EppoNPV in an in vitro tissue culture system.…”

“…Group I alphabaculoviruses use GP64 as their envelope fusion protein (EFP) in the BV phenotype, whereas group II alphabaculoviruses as well as betabaculoviruses and deltabaculoviruses lack GP64 and exploit F protein as the EFP [10]. Studies on the whole genome of baculoviruses are helpful in guiding our current understanding of baculovirus, including the biotechnological use of the viruses and the revelation of intrinsic attributes critical for virus identification and classification, gene function, and insecticidal potential [11,12].…”

The larch looper, Erannis ankeraria Staudinger (Lepidoptera: Geometridae), is one of the major insect pests of larch forests, widely distributed from southeastern Europe to East Asia. A naturally occurring baculovirus, Erannis ankeraria nucleopolyhedrovirus (EranNPV), was isolated from E. ankeraria larvae. This virus was characterized by electron microscopy and by sequencing the whole viral genome. The occlusion bodies (OBs) of EranNPV exhibited irregular polyhedral shapes containing multiple enveloped rod-shaped virions with a single nucleocapsid per virion. The EranNPV genome was 125,247 bp in length with a nucleotide distribution of 34.9% G+C. A total of 131 hypothetical open reading frames (ORFs) were identified, including the 38 baculovirus core genes and five multi-copy genes. Five homologous regions (hrs) were found in the EranNPV genome. Phylogeny and pairwise kimura 2-parameter analysis indicated that EranNPV was a novel group II alphabaculovirus and was most closely related to Apocheima cinerarium NPV (ApciNPV). Field trials showed that EranNPV was effective in controlling E. ankeraria in larch forests. The above results will be relevant to the functional research on EranNPV and promote the use of this virus as a biocontrol agent.

“…Having the total genome sequence of a baculovirus is useful in designing intelligent strategies for biotechnological use of the virus including pest control [8]. To date, the total sequences of 79 baculovirus genome have been deposited in the National Center for Biotechnology Information (NCBI, www.ncbi.nlm.nih.gov) of which, 51 belong to Alphabaculovirus, 24 to Betabaculovirus, 1 to Deltabaculovirus and 3 to Gammabaculovirus.…”

Genome sequence analysis of a Helicoverpa armigera single nucleopolyhedrovirus (HearNPV-TR) isolated from Heliothis peltigera in Turkey

et al. 2020

The entire genome of Helicoverpa armigera single nucleopolyhedrovirus (HearNPV-TR) was sequenced, and compared to genomes of other existing isolates. HearNPV-TR genome is 130.691 base pairs with a 38.9% G+C content and has 137 open reading frames (ORFs) of � 150 nucleotides. Five homologous repeated sequences (hrs) and two baculovirus repeated ORFs (bro-a and bro-b) were identified. Phylogenetic analysis showed that HearNPV-TR is closer to HaSNPV-C1, HaSNPV-G4, HaSNPV-AU and HasNPV. However, there are significant differences in hr3, hr5 regions and in bro-a gene. Pairwise Kimura-2 parameter analysis of 38 core genes sequences of HearNPV-TR and other Helicoverpa NPVs showed that the genetic distances for these sequences were below 0.015 substitutions/site. Genomic differences as revealed by restriction profiles indicated that hr3, hr5 regions and bro-a gene may play a role in the virulence of HearNPV-TR.
