Abstract
Sitobion miscanthi, the main species of wheat aphids, is one kind of harmful pest. Chemical insecticides are the important agrochemical products to effectively control wheat aphids. However, the broad application has led to serious resistance of pests to several insecticides, and understanding insecticide resistance mechanisms is critical for integrated pest management. In this study, SmUGGT1, a new uridine diphosphate (UDP)-glycosyltransferase (UGT) gene, was cloned and more strongly expressed in the SM-R (the resistant strain to imidacloprid) than in the SM-S (the susceptible strain to imidacloprid). The increased susceptibility to imidacloprid was observed after silencing SmUGGT1, indicating that it can be related to the resistance to imidacloprid. Subsequently, SmUGGT1 regulated post-transcriptionally in the coding sequences (CDs) by miR-81 was verified and involved in the resistance to imidacloprid in S. miscanthi. This finding is crucial in the roles of UGT involved in insecticide resistance management in pests.

Abstract
Baculoviruses have been extensively studied for their potential in microbial pest control, but the mechanisms behind their mode of action still need to be addressed. Here we report differential expression of a cellular miRNA, Sfr-miR-184, from Sf9 cells in response to Autographa californica multicapsid Nucleopolyhedrovirus (AcMNPV) infection. Our results showed that Sfr-miR-184 is down-regulated in AcMNPV-infected cells but not with UV-inactivated virus. Prohibitin gene was determined as a target of the miRNA, which was up-regulated following AcMNPV infection. Using synthetic miRNA mimic, we found that oversupply of the miRNA resulted in decreased transcript levels of the target gene. Results suggest that Sfr-miR-184 negatively regulate prohibitin transcripts in the host cells. Antibody-mediated inhibition and silencing of the prohibitin gene revealed significant reductions in virus DNA replication suggesting a possible role for prohibitin in the virus-host interaction. These findings highlight another molecular mechanism used by baculovirus to manipulate host cells for its replication.

Abstract
The wheat aphid Sitobion miscanthi is a dominant and destructive pest in agricultural production. Insecticides are the main substances used for effective control of wheat aphids. However, their extensive application has caused severe resistance of wheat aphids to some insecticides; therefore, exploring resistance mechanisms is essential for wheat aphid management. In the present study, CYP6CY2, a new P450 gene, was isolated and overexpressed in the imidacloprid-resistant strain (SM-R) compared to the imidacloprid-susceptible strain (SM-S). The increased sensitivity of S. miscanthi to imidacloprid after knockdown of CYP6CY2 indicates that it could be associated with imidacloprid resistance. Subsequently, the posttranscriptional regulation of CYP6CY2 in the 3' UTR by miR-3037 was confirmed, and CYP6CY2 participated in imidacloprid resistance. This finding is critical for determining the role of P450 in relation to the resistance of S. miscanthi to imidacloprid. It is of great significance to understand this regulatory mechanism of P450 expression in the resistance of S. miscanthi to neonicotinoids.

Abstract
BACKGROUND MicroRNAs (miRNAs) play a key role in various biological processes by influencing the translation of target messenger RNAs (mRNAs) through post-transcriptional regulation. The miR-184-3p has been identified as an abundant conserved miRNA in insects. However, less is known about its functions in insect-plant virus interactions. RESULTS The function of miR-184-3p in regulation of plant viral infection in insects was investigated using a rice black-streaked dwarf virus (RBSDV) and Laodelphax striatellus (Fallén) interaction system. We found that the expression of miR-184-3p increased in L. striatellus after RBSDV infection. Injection of miR-184-3p mimics increased RBSDV accumulation, while treatment with miR-184-3p antagomirs inhibits the viral accumulation in L. striatellus. Ken, a zinc finger protein, was identified as a target of miR-184-3p. Knockdown of Ken increased the virus accumulation and promoted RBSDV transmission by L. striatellus. CONCLUSION This study demonstrates that RBSDV infection induces the expression of miR-184-3p in its insect vector L. striatellus. The miR-184-3p targets Ken to promote RBSDV accumulation and transmission. These findings provide a new insight into the function of the miRNAs in regulating plant viral infection in its insect vector. © 2023 Society of Chemical Industry.

Abstract
Overuse of insecticides has accelerated the evolution of insecticide resistance and created serious environmental concerns worldwide, thus incentivizing development of alternative methods. Bacillus thuringiensis (Bt) is an insecticidal bacterium that has been developed as a biopesticide to successfully control multiple species of pests. It operates by secreting several insect toxins such as Cry1Ac. However, metabolic resistance based on ATP-binding cassette (ABC) transporters may play a crucial role in the development of metabolic resistance to Bt. Here, we characterized an ABCG gene from the agricultural pest Plutella xylostella (PxABCG3) and found that it was highly expressed in a Cry1Ac-resistant strain, up-regulated after Cry1Ac protoxin treatment. Binding miR-8510a-3p to the coding sequence (CDS) of PxABCG3 was then confirmed by a luciferase reporter assay and RNA immunoprecipitation. miR-8510a-3p agomir delivery markedly reduced PxABCG3 expression in vivo and consequently decreased the tolerance of P. xylostella to Cry1Ac, while reduction of miR-8510a-3p significantly increased PxABCG3 expression, accompanied by an increased tolerance to Cry1Ac. Our results suggest that miR-8510a-3p could potentially be used as a novel molecular target against P. xylostella or other lepidopterans, providing novel insights into developing effective and environmentally friendly pesticides.

Abstract
BACKGROUND Application of insect growth regulators (IGR) is a good option for insect pest management because of their fewer adverse effects on humans and domestic animals. These compounds are capable of interfering with normal growth and development by mimicking the actions of hormones such as juvenile hormone (JH) or ecdysone. The effect of JH and its analogs on some aspects of insect immunity has been determined, yet their possible effects on antiviral immunity response has not been investigated yet. Considering the importance of antiviral response in viral replication, in this study the effects of the JH analog (JHA), fenoxycarb on the antiviral immunity pathway core genes [i.e. micro (mi)RNA, small interfering (si)RNA and apoptosis] of Helicoverpa armigera (Hubner) larvae were investigated. The effect of fenoxycarb on the susceptibility of the larvae to H. armigera nuclear polyhedrosis virus (HaNPV) also was assessed. RESULTS The results showed that the transcription level of miRNA (Dicer1, Ago1), siRNA (Dicer2, Ago2) and apoptosis (Caspase1, Caspase5) core genes in H. armigera larvae were decreased significantly after 24, 48 and 96 h feeding on a diet containing lethal and sublethal doses of fenoxycarb. Moreover, the mortality rate to HaNPV in the larvae treated with fenoxycarb increased compared to the control, leading to an increased replication of HaNPV. CONCLUSION Together, our results suggest that the antiviral immune system could be modulated by JHA and facilitate HaNPV replication in the larvae, increasing the mortality rate of the insect larvae. Understanding the effect of JHA on antiviral immunity is an important step toward the process of exploiting JHAs and viral pathogens to control insect pests. © 2022 Society of Chemical Industry.

Abstract
The insect cell-baculovirus expression vector system (IC-BEVS) has emerged as an alternative time- and cost-efficient production platform for recombinant Adeno-associated virus (AAV) for gene therapy. However, a better understanding of the underlying biological mechanisms of IC-BEVS is fundamental to further optimize this expression system toward increased product titer and quality. Here, gene expression of Sf9 insect cells producing recombinant AAV through a dual baculovirus expression system, with low multiplicity of infection (MOI), was profiled by RNA-seq. An 8-fold increase in reads mapping to either baculovirus or AAV transgene sequences was observed between 24 and 48 h post-infection (hpi), confirming a take-over of the host cell transcriptome by the baculovirus. A total of 336 and 4784 genes were identified as differentially expressed at 24 hpi (vs non-infected cells) and at 48 hpi (vs. infected cells at 24 hpi), respectively, including dronc, birc5/iap5, and prp1. Functional annotation found biological processes such as cell cycle, cell growth, protein folding, and cellular amino acid metabolic processes enriched along infection. This work uncovers transcriptional changes in Sf9 in response to baculovirus infection, which provide new insights into cell and/or metabolic engineering targets that can be leveraged for rational bioprocess engineering of IC-BEVS for AAV production.

Abstract
BACKGROUND MicroRNAs (miRNAs) are small regulatory non-coding RNAs that are involved in a variety of biological processes such as immunity, cell signaling and development by regulating gene expression. The whitefly Bemisia tabaci is a polyphagous vector that transmits many plant viruses causing economic damage to crops worldwide. In this study, we characterized and analyzed the expression of the miRNA core genes Argonaute-1 (Ago1) and Dicer-1 (Dcr1) in B. tabaci and explored the effect of their silencing on the insect's fitness. RESULTS Our results showed that Ago1 and Dcr1 are differentially expressed in different tissues and developmental stages of B. tabaci. To determine the function of the miRNA pathway in B. tabaci, we silenced Ago1 and Dcr1 using specific double-stranded RNAs to the genes. RNA interference (RNAi) of Ago1 and Dcr1 decreased the expression level of the core genes and reduced the abundance of Let-7 and miR-184 miRNAs. Silencing of the miRNA pathway core gene also negatively affected the biology of B. tabaci by reducing fertility, fecundity and survival of this insect pest. CONCLUSIONS Together, our results showed that silencing the miRNA pathway core genes reduced the miRNA levels followed by reduced fecundity and survival of B. tabaci, which highlighted the importance of the miRNA pathway in this insect. The miRNA core genes are attractive targets for developing an RNAi-based strategy for targeting this notorious insect pest. © 2022 Society of Chemical Industry.

Abstract
The fall armyworm Spodoptera frugiperda (Smith) (FAA) is responsible for considerable losses in grain production, and chemical control is the most effective strategy. However, frequent insecticide application can lead to the development of resistance. In insects, cytochrome P450 plays a crucial role in insecticide metabolism. CYP6K2 is related to FAA resistance to chlorantraniliprole. However, the regulatory mechanism of CYP6K2 expression is poorly understood. In this study, a conserved target of isolated miRNA-190-5p was located in the 3' UTR of CYP6K2 in FAA. A luciferase reporter analysis showed that in FAA, miRNA-190-5p can combine with the 3'UTR of CYP6K2 to suppress its expression. Injected miRNA-190-5p agomir significantly reduced CYP6K2 abundance by 54.6% and reduced tolerance to chlorantraniliprole in FAA larvae, whereas injected miRNA-190-5p antagomir significantly increased CYP6K2 abundance by 1.77-fold and thus improved chlorantraniliprole tolerance in FAA larvae. These results provide a basis for further research on the posttranscriptional regulatory mechanism of CYP6K2 and will facilitate further study on the function of miRNAs in regulating tolerance to chlorantraniliprole in FAA.

Abstract
Spodoptera frugiperda is the world’s major agricultural pest and has the distinctive features of high fecundity, strong migratory capacity, and high resistance to most insecticides. At present, the control of S. frugiperda in China relies mainly on the spraying of chemical insecticides. MicroRNAs (miRNAs) are a class of small, single-stranded, non-coding RNAs and play crucial regulatory roles in various physiological processes, including the insecticide resistance in insects. However, little is known about the regulatory roles of miRNAs on the resistance of S. frugiperda to insecticides. In the present research, the miRNAs that were differentially expressed after cyantraniliprole, spinetoram, and emamectin benzoate treatment were analyzed by RNA-Seq. A total of 504 miRNAs were systematically identified from S. frugiperda, and 24, 22, and 31 miRNAs were differentially expressed after treatments of cyantraniliprole, spinetoram, and emamectin benzoate. GO and KEGG enrichment analyses were used to predict the function of differentially expressed target genes of miRNAs. Importantly, ten miRNAs were significantly differentially expressed among the treatments of three insecticides. miR-278-5p, miR-13b-3p, miR-10485-5p, and miR-10483-5p were significantly downregulated among the treatments of three insecticides by RT-qPCR. Furthermore, the overexpression of miR-278-5p, miR-13b-3p, miR-10485-5p, and miR-10483-5p significantly increased the mortality of S. frugiperda to cyantraniliprole and emamectin benzoate. The mortality was significantly increased with spinetoram treatment after the overexpression of miR-13b-3p, miR-10485-5p, and miR-10483-5p. These results suggest that miRNAs, which are differentially expressed in response to insecticides, may play a key regulatory role in the insecticide tolerance in S. frugiperda.

[PMID: 34452456 PMCID: PMC8402809 DOI: 10.3390/v13081591] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/30/2021] [Revised: 08/05/2021] [Accepted: 08/10/2021] [Indexed: 12/29/2022] Open
Abstract
RNA interference (RNAi), especially the small interfering RNA (siRNA) and microRNA (miRNA) pathways, plays an important role in defending against viruses in plants and insects. However, how insect-transmitted phytoviruses regulate the RNAi-mediated antiviral response in vector insects has barely been uncovered. In this study, we explored the interaction between rice stripe virus (RSV) and the miRNA and siRNA pathways of the small brown planthopper, which is a vector insect. The transcript and protein levels of key genes in the two RNAi pathways did not change during the RSV infection process. When the expression of insect Ago1, Ago2, or Translin was silenced by the injection of double-stranded RNAs targeting these genes, viral replication was promoted with Ago2 silencing but inhibited with Translin silencing. Protein-protein binding assays showed that viral NS2 and RNA-dependent RNA polymerase interacted with insect Ago2 and Translin, respectively. When NS2 was knocked down, the transcript level of Ago2 increased and viral replication was inhibited. Therefore, viral NS2 behaved like an siRNA suppressor in vector insects. This protein-binding regulation of insect RNAi systems reflects a complicated and diverse coevolution of viruses with their vector insects.

Abstract
To investigate the role of miR-4301 in rotavirus (RV)-infected Caco-2 cells. In this experiment, RNAs of RV-infected Caco-2 cells were extracted, and the high-throughput second-generation sequencing was performed to detect the expression profiles of host microRNAs (miRNAs). Synthetic miRNA mimics and inhibitors were examined (quantitative polymerase chain reaction [qPCR], crystalline violet, immunofluorescence and electron microscopy) to evaluate the effect on RV replication. Target genes of miR-4301 were predicted by software analysis. The expression of target genes was evaluated by qPCR and Western blot after transfected with miRNA inhibitor/mimic, and crystalline violet and qPCR were used to detect the downregulation effects of target genes on RV replication. By transfecting miRNA inhibitors/mimics and detecting downstream target genes, the mechanism of miRNA affecting RV replication was analyzed. There were 78 known miRNAs with significant differential expression, including 39 upregulated miRNAs and 39 downregulated miRNAs. The results showed that miR-4301 exerted a key role in enhancing RV replication. PPP1R3D protein which can inhibit RV replication was predicted as the target gene of miR-4301 by software analysis. While upregulating miR-4301 by RV, the expression of PPP1R3D and glycogen synthase (GS) is suppressed. For the first time, the effect of miR-4301 on RV infection, and its influence on GS was investigated. Specifically, RV inhibits host cell glycogen synthesis to utilize the host intracellular glucose for promoting its own replication.

Abstract
MicroRNAs (miRNAs), small non-coding RNAs of about 22 nucleotides, have been reported to regulate gene expression at the posttranscriptional level and are involved in several biological processes such as immunity, development, metabolism, and host-pathogen interactions. Apart from miRNAs encoded by the host, miRNAs produced by pathogens also regulate host genes to facilitate virus replication and evasion of the host defense responses. In recent years, accumulated studies suggest that viral infections alter the host miRNAs expression profile, and both cellular and viral miRNAs may play vital roles in host-pathogen interactions. Bombyx mori, one of the critical lepidopteran model species, is an economically important insect for silk production. The mechanism of interaction between B. mori and its pathogens and their regulation by miRNAs has been extensively studied. Therefore, in this review, we aim to highlight the recent information and understanding of the virus-encoding miRNAs and their functions in modulating viral and host (B. mori) genes. Additionally, the response of B. mori derived miRNAs to viral infection is also discussed. A detailed critical view about miRNAs’ regulatory roles in B. mori-virus interactions will help us understand molecular networks and develop a sustainable antiviral strategy.

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.

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
Cry protein toxins produced by Bacillus thuringiensis (Bt) are now widely used in sprays and transgenic crops to control insect pests. Most recently, ATP-binding cassette transporter proteins (ABC transporter), including ABCC2, ABCC3, ABCG1, ABCA2 and ABCB1, were reported as putative receptors for different Cry toxins. However, little is known about the regulatory mechanism involved in the expression of these ABC transporter genes. In the present study, a conserved target site of miR-998-3p was identified from the coding sequence (CDS) of ABCC2 in diverse lepidopteran insects. Luciferase reporter assays demonstrated that miR-998-3p could bind to the CDS of ABCC2 and down-regulate its expression through a conserved site and several non-conserved sites in three representative lepidopteran pests, including Helicoverpa armigera, Spodoptera exigua and Plutella xylostella. Injection of miR-998-3p agomir significantly reduced the abundance of ABCC2, accompanied by increased tolerance to Cry1Ac toxin in H. armigera, S. exigua and P. xylostella (Cry-S) larvae, while injection of miR-998-3p antagomir increased the abundance of ABCC2 dramatically, and thereby reduced the Cry1Ac resistance in a Cry1Ac resistant population of P. xylostella (GX-R). These results give a better understanding of the mechanisms of post-transcriptional regulation of ABCC2, and will be helpful for further studies on the role of miRNAs in the regulation of Cry1Ac resistance in lepidopteran pests.
