Genome sequence of a Bombyx mori nucleopolyhedrovirus strain with cubic occlusion bodies.

ABSTRACT: Bombyx mori nucleopolyhedrovirus (BmNPV) is a typical species of Baculoviridae. The complete genome sequence of a BmNPV strain with cubic occlusion bodies is reported here. The genome of this strain consists of 127,465 nucleotides with a G+C content of 40.36% and is 97.3% and 97.5% identical to those of BmNPV strain T3 and Bombyx mandarina NPV S1, respectively. Despite the abnormal polyhedra it forms, the polyhedrin gene of the BmNPV cubic strain is 100% identical to those of the other two strains. Baculovirus repeated ORFs and homologous repeat regions cause the major differences in genome size of these BmNPV isolates.

Infectious Virions of Bombyx Mori Latent Virus Are Incorporated into Bombyx Mori Nucleopolyhedrovirus Occlusion Bodies.

Project description:The Bombyx mori latent virus (BmLV) belongs to the unassigned plant virus family Tymoviridae and contains a positive-sense, single-stranded RNA genome. BmLV has infected almost all B. mori-derived cultured cell lines through unknown routes. The source of BmLV infection and the BmLV life cycle are still unknown. Here, we examined the interaction between BmLV and the insect DNA virus Bombyx mori nucleopolyhedrovirus (BmNPV). Persistent infection with BmLV caused a slight delay in BmNPV propagation, and BmLV propagation was enhanced in B. mori larvae via co-infection with BmNPV. We also showed that BmLV infectious virions were co-occluded with BmNPV virions into BmNPV occlusion bodies. We propose a new relationship between BmLV and BmNPV.

Genome of a Bombyx mori nucleopolyhedrovirus strain isolated from India.

Project description:Bombyx mori nucleopolyhedrovirus (BmNPV), a member of the Baculoviridae, is a major pathogen of silkworm and has also been recently developed as an expression vector for heterologous gene expression in the silkworm larvae and pupae. To better understand the diversity of this important baculovirus, we sequenced the complete genome of the BmNPV strain isolated from India, where its host is available throughout the year due to its tropical climate. The genome of the Indian strain consists of 127,879 nucleotides, with a G+C content of 40.36%. There are 138 open reading frames (ORFs) encoding the predicted proteins of more than 50 amino acids. Genomic comparison of the Indian strain with 3 other reported BmNPV strains showed that the baculovirus repeat ORFs (bro) and homologous repeat regions (hr's) are highly variable. These results suggest that the BmNPV strain heterogeneity is mainly caused by single-nucleotide polymorphisms (SNPs) and changes in the hr's and bro genes.

Patterns in Genotype Composition of Indian Isolates of the Bombyx mori Nucleopolyhedrovirus and Bombyx mori Bidensovirus.

Project description:The mulberry silkworm, Bombyx mori (L.), is a model organism of lepidopteran insects with high economic importance. The viral diseases of the silkworm caused by Bombyx mori nucleopolyhedrovirus (BmNPV) and Bombyx mori bidensovirus (BmBDV) inflict huge economic losses and significantly impact the sericulture industry of India and other countries. To understand the distribution of Indian isolates of the BmNPV and to investigate their genetic composition, an in-depth population structure analysis was conducted using comprehensive and newly developed genomic analysis methods. The seven new Indian BmNPV isolates from Anantapur, Dehradun, Ghumarwin, Jammu, Kashmir, Mysore and Salem grouped in the BmNPV clade, and are most closely related to Autographa californica multiple nucleopolyhedrovirus and Rachiplusia ou multiple nucleopolyhedrovirus on the basis of gene sequencing and phylogenetic analyses of the partial polh, lef-8 and lef-9 gene fragments. The whole genome sequencing of three Indian BmNPV isolates from Mysore (-My), Jammu (-Ja) and Dehradun (-De) was conducted, and intra-isolate genetic variability was analyzed on the basis of variable SNP positions and the frequencies of alternative nucleotides. The results revealed that the BmNPV-De and BmNPV-Ja isolates are highly similar in their genotypic composition, whereas the population structure of BmNPV-My appeared rather pure and homogenous, with almost no or few genetic variations. The BmNPV-De and BmNPV-Ja samples further contained a significant amount of BmBDV belonging to the Bidnaviridae family. We elucidated the genotype composition within Indian BmNPV and BmBDV isolates, and the results presented have broad implications for our understanding of the genetic diversity and evolution of BmNPV and co-occurring BmBDV isolates.

Genomic Sequence Analysis of <i>Bombyx mori</i> Nucleopolyhedrovirus Isolated from Yunnan Sericulture Region, China.

Project description:The blood pathogens of grasserie caused by Bombyx mori nucleopolyhedrovirus BmNPV have a serious impact on the sericulture industry. To understand the genetic status of BmNPV endemic strains in the Yunnan sericulture region, the structure and complete genome sequence of BmNPV isolated from Baoshan city of Yunnan Province were described and compared to known strains. The BmNPV-Baoshan isolate was a nucleopolyhedrovirus parasitized in silkworm larvae. Its genome has 128, 452 bp with a G + C content of 40.4%. Phylogenetic analysis clustered the virus with China BmNPV isolates; BmNPV-Baoshan was closely related to BomaNPV-S1 (both strains originated from the same ancestor). BmNPV-Baoshan strain has bro-b gene deletion, hr1 missing 4 repeat units of 30-bp palindrome structure compared to BmNPV-T3 strain. The aim of this study was to elucidate the evolution of the virus further and provide insights for the protection of virus-induced hematologic sepsis.

Midgut membrane protein BmSUH facilitates Bombyx mori nucleopolyhedrovirus oral infection.

Project description:Baculoviruses are virulent pathogens that infect a wide range of insects. They initiate infections via specific interactions between the structural proteins on the envelopes of occlusion-derived virions (ODVs) and the midgut cell surface receptors in hosts. However, host factors that are hijacked by baculoviruses for efficient infection remain largely unknown. In this study, we identified a membrane-associated protein sucrose hydrolase (BmSUH) as an ODV binding factor during Bombyx mori nucleopolyhedrovirus (BmNPV) primary infection. BmSUH was specifically expressed in the midgut microvilli where the ODV-midgut fusion happened. Knockout of BmSUH by CRISPR/Cas9 resulted in a significantly higher survival rate after BmNPV orally infection. Liquid chromatography-tandem mass spectrometry analysis and co-immunoprecipitation analysis demonstrated that PIF protein complex required for ODV binding could interact with BmSUH. Furthermore, fluorescence dequenching assay showed that the amount of ODV binding and fusion to the midgut decreased in BmSUH mutants compared to wild-type silkworm, suggesting the role of BmSUH as an ODV binding factor that mediates the ODV entry process. Based on a multilevel survey, the data showed that BmSUH acted as a host factor that facilitates BmNPV oral infection. More generally, this study indicated that disrupting essential protein-protein interactions required for baculovirus efficient entry may be broadly applicable to against viral infection.

Bombyx mori Nucleopolyhedrovirus p26 Is Associated with Viral Late Stage Replication.

Project description:Bombyx mori nucleopolyhedrovirus (BmNPV) p26 is conserved among all Lepidoptera baculoviruses that have been completely sequenced thus far, and some baculoviruses even have two copies of p26, which suggested that p26 may play an important role in the virus infection cycle. This study aimed to characterize BmNPV p26. We found that BmNPV p26 transcripts were detectable as early as 3 h post-infection (hpi), and the transcript levels rapidly increased starting from 12 hpi. Western blot analysis using an anti-p26 polyclonal antibody demonstrated that the corresponding protein was also detectable from 6 hpi in BmNPV-infected cell lysates. Immunofluorescence analysis demonstrated that p26 was mainly dispersed in the infected cell cytoplasm, whereas the over-expressed fusion protein EGFP-p26 also accumulated in the nucleus. These results indicated that p26 is an early BmNPV gene and has functions both in the cytoplasm and the nucleus. RNAi-based knockdown of p26 could produce infectious virus and normal-appearing virions but decreased budded virus (BV) production in BmNPV-infected cells at 72 hpi. Moreover, the results of further quantitative PCR (Q-PCR) analysis indicated that the gp64 and p74 transcripts levels decreased significantly. These results indicated that BmNPV p26 may be associated with BmNPV replication during the late infection stage.

Characterization of baculovirus repeated open reading frames (bro) in Bombyx mori nucleopolyhedrovirus.

Project description:The baculovirus Bombyx mori nucleopolyhedrovirus (BmNPV) contains five related open reading frames (ORFs). Recent sequence analyses of several other baculovirus genomes reveal that these ORFs belong to a unique multigene family called the baculovirus repeated ORFs (bro) family. Here we have characterized these five genes from BmNPV at the transcriptional and translational levels. Reverse transcription-PCR and primer extension analyses indicated that transcription of all bro genes occurs by 2 to 4 h postinfection (p.i.) and reaches maximal levels between at 8 and 12 h p.i. Transcription of all genes is initiated between 50 and 70 nucleotides upstream of the start codon, at a characteristic C(T)AGT motif. Expression of a cat reporter gene under the control of each bro promoter provides evidence that a viral factor(s) is required for the transcription of all bro genes. Immunoblot analysis indicated that a population of BRO proteins is produced vigorously between at 8 and 14 h p.i. Immunohistochemical analysis by confocal microscopy showed that BRO proteins are localized in both the nucleus and the cytoplasm at 8 h p.i. Four BmNPV mutants, in which the bro-a, bro-b, bro-c, and bro-e genes were individually inactivated, were successfully isolated. However, exhaustive efforts failed to isolate a bro-d-deficient mutant. Similarly, it was not possible to isolate a double-deletion bro-a bro-c mutant. The bro-d gene may play an irreplaceable functional role(s) during viral infection, while bro-a and bro-c may functionally complement each other.

V-ATPase Is Involved in Silkworm Defense Response against Bombyx mori Nucleopolyhedrovirus.

Project description:Silkworms are usually susceptible to the infection of Bombyx mori (B. mori) nucleopolyhedrovirus (BmNPV), which can cause significant economic loss. However, some silkworm strains are identified to be highly resistant to BmNPV. To explore the silkworm genes involved in this resistance in the present study, we performed comparative real-time PCR, ATPase assay, over-expression and sub-cellular localization experiments. We found that when inoculated with BmNPV both the expression and activity of V-ATPase were significantly up-regulated in the midgut column cells (not the goblet cells) of BmNPV-resistant strains (NB and BC8), the main sites for the first step of BmNPV invasion, but not in those of a BmNPV-susceptible strain 306. Furthermore, this up-regulation mainly took place during the first 24 hours post inoculation (hpi), the essential period required for establishment of virus infection, and then was down-regulated to normal levels. Amazingly, transient over-expression of V-ATPase c subunit in BmNPV-infected silkworm cells could significantly inhibit BmNPV proliferation. To our knowledge this is the first report demonstrating clearly that V-ATPase is indeed involved in the defense response against BmNPV. Our data further suggests that prompt and potent regulation of V-ATPase may be essential for execution of this response, which may enable fast acidification of endosomes and/or lysosomes to render them competent for degradation of invading viruses.
