Project description:Ubiquitin-fold modifier 1 (UFM1) is attached to protein substrates through the sequential activity of an E1 (UBA5)-E2 (UBC1)-E3 (UBL1) cascade. UFBP1 is a conserved UFL1-interacting protein in mammals. However, there is no study on UFBP1 in silkworm yet. In this study, we identified a UFBP1 ortholog in B. mori genome. Spatio-Temporal expression profiles showed that BmUFBP1 expression was highly in midgut, fatbody, and at the moth stage. BmUFBP1 knockdown inhibited ER-stress induced ER chaperone expression and BmNPV proliferation, while BmUFBP1 overexpression increased BmNPV proliferation. Furthermore, RNA sequencing and experimental verification identified the HSP70 family member BmBIP as the BmUFBP1 downstream target in regulating BmNPV proliferation. Overall, these results suggest that BmUFBP1 facilitates BmNPV proliferation via ATF6-BIP signaling.

Project description:Bombyx mori nucleopolyhedrovirus (BmNPV) is one of the most acute infectious diseases in silkworm, which has caused great economic loss in sericulture. Previous study showed that the content of components in mulberry leaves, particularly for moracin N, was increased after UV-B irradiation. In this study, the BmNPV resistance of silkworms reared on UV-B treated and moracin N spreaded mulberry leaves was improved. To uncover the mechanism of enhanced BmNPV resistance, silkworm midguts from UV-B treated mulberry leaves (BUM) and moracin N (BNM) groups were analyzed by SWATH-based proteomic technique. Of note, the abundance of ribosomal proteins in BUM and BNM groups was significantly changed to maintain the synthesis of total protein levels and cell survival. While, cytochrome c oxidase subunit II, calcium ATPase and programmed cell death 4 involved in apoptotic process were up-regulated in BNM group. Expressions of lipase-1, serine protease precursor, Rab1 protein, and histone genes were increased significantly in BNM group. These results suggest that moracin N might be the main active components in UV-B treated mulberry leaves to affect the BmNPV-resistance of silkworm, which could promote apoptotic cell death, enhance the organism immunity, and regulate the intercellular environment of cells in silkworm. It also presents an innovative process to reduce the mortality rate of silkworm infected with BmNPV.

Project description:The molecular mechanism involved in BmNPV resistance was investigated using a genome wide microarray in the midgut tissues of BmNPV infected resistant (Sarupat) and susceptible (CSR-2) Indian silkworm races. In the resistant race, 735 genes were upregulated and 589 genes were down regulated at 12 hours of BmNPV post infection. Similarly in case of susceptible race, 2183 genes were up regulated and 2115 genes were down regulated. Among the differentially expressed genes, nine upregulated and eight down regulated genes were validated using real time qPCR analysis. In Sarupat, the significantly upregulated genes are vacuolar protein sorting associated gene, X fin like protein and Carboxy peptidase E like protein in BmNPV infected midguts, whereas the prominent down regulated genes are glutamate receptor ionotropic kainite 2-like, BTB/POZ domain and transferrin. In the case of CSR-2, the considerably upregulated genes are Peptidoglycan recognition protein S6 precursor and rapamycin while the conspicuous down regulated genes are facilitated trehalose transporter and zinc transporter ZIP1-like gene. Our results provided a vital insights of Bombyx mori in reference with its molecular mechanism in immune response against the BmNPV invasion.

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.

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.
