Abstract
The mulberry silkworm Bombyx mori, apart from its well-known economic importance, has also emerged as an insect model to study host-pathogen interactions. The major concern for silkworm cultivation and the sericulture industry is the attack by various types of pathogens mainly includes viruses, fungi, bacteria and protozoa. Successful infection requires specific arsenals to counter the host immune response. MicroRNAs (miRNAs) are one of the potential arsenals which are encoded by viruses and effectively used during host-pathogen interactions. MiRNAs are short noncoding 19-25 nucleotides long endogenous RNAs that post-transcriptionally regulate expression of protein-coding genes in a sequencespecific manner. Most of the higher eukaryotes encode miRNAs and utilize them in the regulation of important cellular pathways. In silkworm, promising functions of miRNAs have been characterized in development, metamorphosis, immunity, and host-pathogen interactions. The viral miRNA-mediated fine-tuning of the viral, as well as cellular genes, is beneficial for making a cellular environment favorable for the virus proliferation. Baculovirus and cypovirus which infect silkworm have been shown to encode miRNAs and their functions are implicated in controlling the expression of both viral and host genes. In the present review, the author discusses the diverse functions of viral-encoded miRNAs in evasion of the host immune responses and reshaping of the silkworm cellular environment for replication. Besides, a basic overview of miRNA biogenesis and mechanism of action is also provided. Our increasing understanding of the viral miRNAs role in silkworm-virus interactions would not only assist us to get insights into the intricate pathways but also provide tools to deal with dreaded pathogens.

[PMID: 31840397 DOI: 10.1111/1744-7917.12745] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/15/2019] [Revised: 10/22/2019] [Accepted: 11/21/2019] [Indexed: 06/10/2023]
Abstract
Metamorphosis is one of the most important physiological processes in insects. It is regulated by a serial of ecdysone cascade genes. Recently, lots of microRNAs (miRNAs) were investigated in insects; however, their function in metamorphosis is largely unknown. In the present study, the dynamics of a small RNA population was investigated by RNA sequencing from the midgut of a lepidopteran pest Spodoptera litura during larval-pupal metamorphosis. A total of 101 miRNAs were identified, and 75 miRNAs were differentially expressed during the metamorphic process. The relationship between these differentially expressed miRNAs and 12 ecdysone cascade genes was analyzed by four classical software programs, and a multiple-to-multiple regulatory network was found to exist between these miRNAs and their targets. Among them, miR-14-3p and its two targets (EcR and E75) were chosen for further validation. MiR-14-3p had higher expression level in the 6th instar larvae as compared with either the prepupae or pupae, which was opposite to that of both EcR and E75, two ecdysone cascade genes. Luciferase reporter assay confirmed that both EcR and E75 were regulated by miR-14-3p. Interestingly, the 3' untranslated regions are nearly identical to each other among different transcript variants of the ecdysone cascade genes, including EcR, USP, E75, E74, E78, E93, Hr3, Hr4, Hr39, Krh1 and Ftzf1. Thus, different transcript variants of one ecdysone cascade gene could be regulated by the same miRNA. The above data suggest that the ecdysone signaling pathway is under the tight control of miRNA. These findings expand our understanding of the mechanism of insect metamorphosis and may also provide a novel possibility for the control of pest insects in the future.

Singh CP. Role of microRNAs in insect-baculovirus interactions. INSECT BIOCHEMISTRY AND MOLECULAR BIOLOGY 2020; 127:103459. [PMID: 32961323 DOI: 10.1016/j.ibmb.2020.103459] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/15/2020] [Revised: 08/18/2020] [Accepted: 08/26/2020] [Indexed: 06/11/2023]
Abstract
MicroRNAs (miRNAs) constitute a novel class of gene expression regulators and are found to be involved in regulating a wide range of biological processes such as development, cell cycle, metabolism, apoptosis, immunity, host-pathogen interactions etc. Generally miRNAs negatively regulate the gene expression at the post-transcriptional level by binding to the complementary target mRNA sequences. These tiny molecules are abundantly found in higher eukaryotes and viruses. Most of the DNA viruses of animals and insects encode miRNAs including baculoviruses. Baculoviruses are the insect-specific viruses that cause severe infection and mortality mainly in insect larvae of the order Lepidoptera, Diptera, and Hymenoptera. These enveloped viruses have multiple applications in biotechnology and biological pest control methods. For a better understanding of baculoviruses, it is necessary to elucidate the molecular basis of insect-baculovirus interactions. Recent advancement in the technologies for studying the gene expression has accelerated the discovery of new players in the insect-baculovirus interactions. MiRNAs are the emerging and fate-determining players of host-viral interactions. The long history of host and virus co-evolution suggests that the virus keeps on evolving its arsenals to succeed in infection whereas the host continues investing in antiviral defense mechanisms. In this review, I aim to highlight the recent information and understanding of the baculovirus-encoding miRNAs and their functions in regulating viral as well as host genes. Additionally, insect-derived miRNAs response to baculovirus infection is also discussed. A detailed critical view about the regulatory roles of miRNAs in insect-baculovirus interactions will help us to understand molecular networks amid these interactions and develop a sustainable antiviral strategy.

Abstract
A large number of circular RNAs (circRNAs) have been found in different organisms; however, their function in the regulation of histone modification remains unknown. In this study, we found that the circRNA circEgg, cyclized by the 9th-13th exon of Bombyx mori histone-lysine N-methyltransferase eggless (BmEgg) gene, mainly distributes in the cytoplasm, its expression levels changed with silkworm developmental stages, and the linear transcript level of the BmEgg gene was decreased when circEgg was overexpressed. Moreover, circEgg was found to repress histone H3 lysine 9 methylation (H3K9me3), promote histone H3 lysine 9 acetylation (H3K9ac), and positively regulate histone deacetylase (HDAC) Rpd3 (BmHDAC Rpd3) gene expression by sponging the microRNA bmo-miR-3391-5p. Furthermore, circEgg encodes a circEgg-P122 protein which appears to inhibit H3K9me3. These results suggest that circEgg regulates histone modification by sponging bmo-miR-3391-5p and encoding circEgg-P122 protein. To our knowledge, this is the first report showing that a circRNA produced by BmEgg plays an important role in histone epigenetic modification.

Abstract
MicroRNA is an important regulation factor in insect development and metamorphosis. It has been reported that E(spl)m4 is a miRNA-targeted gene, as well as the target of the Notch signaling pathway in Drosophila. The expression of E(spl)m4 can be regulated by microRNA and further affect the neural development of Drosophila. Here, we found that BmEm4, an ortholog of E(spl)m4 from Bombyx mori, was the target gene of bmo-miR-79, with target sites containing the Brd and K boxes of the BmEm4_3'UTR, which was validated by the dual luciferase reporter (DLR) assay. Furthermore, bmo-miR-79 mimics can inhibit the expression of BmEm4 in BmN cells after transfection, and bmo-miR-79 can also inhibit the expression of BmEm4 in different developmental stages of Bombyx mori at a posttranscriptional level, to different degrees. The EMSA test further showed that bmo-miR-79 could bind to BmAGO2, which is the Bombyx mori argonaute2 protein, suggesting that bmo-miR-79 might regulate the expression of BmEm4 by forming miRISC complexes with BmAGO2. Taken together, bmo-miR-79 could regulate the expression of BmEm4 mediated by BmAGO2 and further affect its function in the silkworm Bombyx mori.

Abstract
Transgenic maize hybrids that express insecticidal Bacillus thuringiensis (Bt) crystalline (Cry) protein toxins effectively protect against the European corn borer, Ostrinia nubilalis, a devastating maize pest. Field monitoring and laboratory selections have detected varying levels of O. nubilalis resistance to Cry1Ab toxin. MicroRNAs (miRNAs) are short noncoding RNAs that are involved in post-transcriptional gene regulation. Their potential roles in the evolution of Bt resistance, however, remain largely unknown. Sequencing of small RNA libraries from the midgut of Cry1Ab-susceptible and resistant O. nubilalis larvae resulted in the discovery of 277 miRNAs, including 248 conserved and 29 novel. Comparative analyses of miRNA expression profiles between the laboratory strains predicted 26 and nine significantly up- and down-regulated transcripts, respectively, in the midgut of Cry1Ab resistant larvae. Amongst 15 differentially regulated miRNAs examined by quantitative real-time PCR, nine (60%) were validated as cosegregating with Cry1Ab resistance in a backcross progeny. Differentially expressed miRNAs were predicted to affect transcripts involved in cell membrane components with functions in metabolism and binding, and the putative Bt-resistance genes aminopeptidase N and cadherin. These results lay the foundation for future investigation of the potential role of miRNAs in the evolution of Bt resistance.

Abstract
BACKGROUND Helicoverpa armigera and Helicoverpa zea are major caterpillar pests of Old and New World agriculture, respectively. Both, particularly H. armigera, are extremely polyphagous, and H. armigera has developed resistance to many insecticides. Here we use comparative genomics, transcriptomics and resequencing to elucidate the genetic basis for their properties as pests. RESULTS We find that, prior to their divergence about 1.5 Mya, the H. armigera/H. zea lineage had accumulated up to more than 100 more members of specific detoxification and digestion gene families and more than 100 extra gustatory receptor genes, compared to other lepidopterans with narrower host ranges. The two genomes remain very similar in gene content and order, but H. armigera is more polymorphic overall, and H. zea has lost several detoxification genes, as well as about 50 gustatory receptor genes. It also lacks certain genes and alleles conferring insecticide resistance found in H. armigera. Non-synonymous sites in the expanded gene families above are rapidly diverging, both between paralogues and between orthologues in the two species. Whole genome transcriptomic analyses of H. armigera larvae show widely divergent responses to different host plants, including responses among many of the duplicated detoxification and digestion genes. CONCLUSIONS The extreme polyphagy of the two heliothines is associated with extensive amplification and neofunctionalisation of genes involved in host finding and use, coupled with versatile transcriptional responses on different hosts. H. armigera's invasion of the Americas in recent years means that hybridisation could generate populations that are both locally adapted and insecticide resistant.

Abstract
Excessive and continuous application of deltamethrin has resulted in the development of deltamethrin resistance among mosquitoes, which becomes a major obstacle for mosquito control. In a previous study, differentially expressed miRNAs between deltamethrin-susceptible (DS) strain and deltamethrin-resistant (DR) strain using illumina sequencing in Culex pipiens pallens were identified. In this study, we applied RNAi and the Centers for Disease Control and Prevention (CDC) bottle bioassay to investigate the relationship between miR-2∼13∼71 cluster (miR-2, miR-13 and miR-71) and deltamethrin resistance. We used quantitative real-time PCR (qRT-PCR) to measure expression levels of miR-2∼13∼71 clusters. MiR-2∼13∼71 cluster was down regulated in adult female mosquitoes from the DR strain and played important roles in deltamethrin resistance through regulating target genes, CYP9J35 and CYP325BG3. Knocking down CYP9J35 and CYP325BG3 resulted in decreased mortality of DR mosquitoes. This study provides the first evidence that miRNA clusters are associated with deltamethrin resistance in mosquitoes. Moreover, we investigated the regulatory networks formed between miR-2∼13∼71 cluster and its target genes, which provide a better understanding of the mechanism involved in deltamethrin resistance.
