Abstract
BACKGROUND Because of the excessive use of synthetic chemicals, the two-spotted spider mite, Tetranychus urticae Koch, a highly polyphagous pest, has developed comprehensive resistance to a broad spectrum of pesticides with diverse modes of action, raising severe concerns over agroecosystems and human health. To resolve this emerging issue, we initiated a project to develop double-stranded RNA (dsRNA)-based biopesticides against T. urticae, aiming for a species-specific and sustainable pest management alternative. RESULTS To examine the uptake of dsRNAs using the egg-soaking delivery method, we fluorescently labeled extraneous dsRNAs, and later showed that T. urticae dsRNAs can permeate through eggshell in a time-dependent manner within the first 24 h. For target gene screening, silencing of Prosbeta-1 and -5 resulted in the highest mortality (>90%) and a dark body phenotype in T. urticae. Notably, each target gene was effective in both avermectin laboratory susceptible and field resistant populations. As such, Prosbeta-5 was selected as the candidate target gene for subsequent spray-induced gene silencing (SIGS). After two rounds of spray at day 5 and day 12, SIGS led to a substantial suppression of T. urticae populations (>90%). CONCLUSION Our combined results suggest viable molecular targets, confirm the feasibility of SIGS against T. urticae, and lay the foundation for the development of dsRNA-based biopesticides to control this devastating pest. © 2025 The Author(s).

Abstract
RNA interference (RNAi) is increasingly used for plant protection against pathogens and pests. However, the traditional delivery method causes plant tissue damage, is affected by environmental factors, and faces difficulties in penetrating the barriers of cell walls and the limitations of plant species, ultimately leading to low delivery efficiency. With advances in nanotechnology, nanomaterials (NMs) have been identified as effective carriers for nucleic acid delivery because of their ability to operate independently of external mechanical forces, prevent degradation by bioenzymes, exhibit good biocompatibility, and offer high loading capacity. This review summarizes the application of NM-mediated RNAi against plant pathogens and pests, focusing on how different NMs break through the cell barriers of plants, pathogens, and pests according to their size, morphology, and charge characteristics. Furthermore, we discuss the advantages and improvement strategies of NMs as nucleic acid delivery carriers, alongside assessing their potential application for the management of plant pathogens and pests.

Abstract
RNA interference (RNAi) has emerged as a potent mechanism for combating pathogenic fungi and oomycetes over the past decades. It offers a promising gene-silencing approach by targeting crucial genes involved in diseases caused by economically and scientifically significant fungal pathogens, such as Botrytis cinerea and Fusarium species. Simultaneously, nano-agro-products have gained attention as alternatives to traditional fungicides in plant protection strategies. However, the instability of naked RNA molecules outside the cellular environment presents a challenge, as they degrade rapidly, limiting their efficacy for prolonged disease control. Concerns regarding the toxicity of protective nanoparticles to non-target organisms have also arisen. Integrating RNAi with nano-agro-products, particularly nanocarriers, to form RNA-nano complexes has demonstrated significant potential, providing enhanced RNA stability, reduced toxicity, and extended disease control. This review explores the mechanisms of RNA-nano complexes-mediated plant protection, addressing RNA stability and nano-toxicity issues while examining the prospects of RNA-nano complex research in plant pathogen management.

Abstract
Wings are important organs of insects involved in flight, mating, and other behaviors, and are therefore prime targets for pest control. The formation of insect wings is a complex process that is regulated by multiple pathways. The Hedgehog (Hh) pathway regulates the distribution of wing veins, while the Hippo pathway modulates wing size. Any interventions that can manipulate these pathways have the potential to disrupt wing development and could be used for pest control. In this study, we find that overexpression of miR-7 in Drosophila results in smaller wings with disordered veins. Mechanistically, miR-7 directly targets both ci and yki via different mature miRNAs (miR-7-5p and miR-7-3p), thereby disrupting the Hh and Hippo pathways. Importantly, this regulatory mechanism is also observed in another insect species, Helicoverpa armigera. Finally, by utilizing a nanocarrier delivery system, we show that introducing miR-7 via star polycation (SPc) leads to wing defects in H. armigera. In conclusion, these findings uncover that miR-7 inhibits wing formation by targeting both the Hippo and Hh pathways, indicating its potential for use in pest control strategies.

Abstract
Prokaryotes and eukaryotes secrete extracellular vesicles (EVs) into the surrounding milieu to preserve and transport elevated concentrations of biomolecules across long distances. EVs encapsulate metabolites, DNA, RNA, and proteins, whose abundance and composition fluctuate depending on environmental cues. EVs are involved in eukaryote-to-prokaryote communication owing to their ability to navigate different ecological niches and exchange molecular cargo between the two domains. Among the different bacterium-host relationships, rhizobium-legume symbiosis is one of the closest known to nature. A crucial developmental stage of symbiosis is the formation of N2-fixing root nodules by the plant. These nodules contain endocytosed rhizobia─called bacteroids─confined by plant-derived peribacteroid membranes. The unrestricted interface between the bacterial external membrane and the peribacteroid membrane is the peribacteroid space. Many molecular aspects of symbiosis have been studied, but the interbacterial and interdomain molecule trafficking by EVs in the peribacteroid space has not been questioned yet. Here, we unveil intensive EV trafficking within the symbiosome interface of several rhizobium-legume dual systems by developing a robust EV isolation procedure. We analyze the EV-encased proteomes from the peribacteroid space of each bacterium-host partnership, uncovering both conserved and differential traits of every symbiotic system. This study opens the gates for designing EV-based biotechnological tools for sustainable agriculture.

Abstract
False smut caused by Ustilaginoidea virens is one of the most destructive diseases in rice. The disease is primarily controlled with fungicides, leading to the development of fungicide resistance. Although spray-induced gene silencing (SIGS) has been utilized for disease management, it has not been applied to control rice false smut. In this study, we introduce a novel approach involving the in vivo synthesis and exogenous application of double-stranded RNA (dsRNA) to manage rice false smut disease. The UvCYP51, UvBI-1, and UvbZIP11 genes were selected as target genes and highly efficient fragments for gene silencing were identified through screening of silencing transformants. Although direct dsRNA uptake by U. virens was not observed, in vivo synthesis and application of dsRNA to rice effectively reduced the expression of target genes. Treatment with dsRNA targeting the genes resulted in a decrease in smut balls, providing a promising disease management strategy against rice false smut.

Abstract
BACKGROUND Migratory insect infestation caused by Sogatella furcifera is a serious threat to rice production. The most effective method available for S. furcifera control is intensive insecticide spraying, which cause widespread resistance. RNA interference (RNAi) insecticides hold enormous potential in managing pest resistance. However, the instability and the poor efficiency of cross-kingdom RNA trafficking are key obstacles for the application in agricultural pest management. METHODS We present dendritic mesoporous silica nanoparticles (DMSNs)-based nanocarrier for delivering siRNA and nitenpyram to inhibit the metabolic detoxification and development of S. furcifera, thereby preventing its proliferation. RESULTS This nano complex (denoted as N@UK-siRNA/DMSNs) significantly enhanced the stability of siRNA (efficacy lasting 21 days) and released cargos in GSH or planthopper bodily fluid with a maximum release rate of 84.99%. Moreover, the released UK-siRNA targeting two transcription factors (Ultraspiracle and Krüppel-homolog 1) downregulated the developmental genes Ultraspiracle (0.09-fold) and Krüppel-homolog 1 (0.284-fold), and downstream detoxification genes ABC SfABCH4 (0.016-fold) and P450 CYP6FJ3 (0.367-fold). CONCLUSION The N@UK-siRNA/DMSNs inhibited pest development and detoxification, significantly enhancing susceptibility to nitenpyram to nanogram level (LC50 is 250-252 ng/mL), resulting in a 5.37-7.13-fold synergistic ratio. This work proposes a comprehensive management strategy for controlling S. furcifera to ensure the green and safe production of rice.

Abstract
Spray-induced gene silencing (SIGS) presents a promising RNA interference (RNAi)-based crop protection strategy against eukaryotic phytopathogens. However, the application of SIGS faces challenges, such as the limited uptake of dsRNA by certain pathogens and the instability of dsRNA in the environment. This study introduces innovative biomimetic nanovesicles, called extracellular vesicle (EV) mimetic chimeric nanovesicles (ECNs), assembled from tomato leaf cell membranes and cationic sterosomes via the freeze-thaw method. Similar to the function of EVs in nucleic acid transport between cells, ECNs serve as a hybrid nanosystem to overcome the challenge of delivering exogenous dsRNA in Phytophthora infestans. When applied to SIGS, the superiority of ECNs in crop protection becomes more apparent, including high loading and protection of dsRNA, improved biosafety, and efficient internalization into pathogen and plant cells, all of which significantly enhance the efficacy of RNAi in preventing early infection of P. infestans to susceptible tomato plants. This study demonstrates that ECNs are promising RNA delivery vehicles and will promote the use of SIGS-based RNA pesticides in sustainable agricultural production.

Abstract
Recent advancements in the field of plant-pathogen interactions have spotlighted the role of extracellular vesicles (EVs) as pivotal mediators of cross-kingdom communication, offering new vistas for enhancing crop protection strategies. EVs are instrumental in the transport of small regulatory RNAs (sRNAs) and other bioactive molecules across species boundaries, thus playing a critical role in the molecular warfare between plants and pathogens. This review elucidates the sophisticated mechanisms by which plants utilize EVs to dispatch sRNAs that silence pathogenic genes, fortifying defenses against microbial threats. Highlighting both eukaryotic and prokaryotic systems, this review delves into the biogenesis, isolation, and functional roles of EVs, illustrating their importance not only in fundamental biological processes but also in potential therapeutic applications. Recent studies have illuminated the significant role of EVs in facilitating communication between plants and pathogens, highlighting their potential in host-defense mechanisms. However, despite these advancements, challenges remain in the efficient isolation and characterization of plant-derived EVs. Overcoming these challenges is critical for fully harnessing their potential in developing next-generation crop protection strategies. This review proposes innovative strategies for utilizing RNA-based interventions delivered via EVs to bolster plant resilience against diseases. By integrating the latest scientific findings with practical applications in agriculture, this review aims to enhance the connection between fundamental plant biology and the development of innovative crop management technologies.

Abstract
RNA interference (RNAi) shows great potential in plant defense against pathogens through RNA-mediated sequence-specific gene silencing. Among RNAi-based plant protection strategies, spray-induced gene silencing (SIGS) is considered a more promising approach because it utilizes the transfer of exogenous RNA between plants and microbes to silence target pathogen genes. The application of nanovesicles significantly enhances RNA stability and delivery efficiency, thereby improving the effectiveness of SIGS and further enhancing plant resistance to diseases and pathogens. This review explores the role of RNAi in plant protection, focusing on the cross-kingdom transport of small RNAs (sRNAs) via extracellular vesicles. It also explores the potential of nanotechnology to further optimize RNA-based plant protection, offering innovative tools and methods in modern plant biotechnology.

Abstract
How organ size is determined is a fundamental question in life sciences. Recent studies have highlighted the importance of the Hippo pathway in regulating organ size. This pathway controls cell proliferation and cell death to maintain the proper number of cells. The activity of the Hippo pathway is tightly fine-tuned through various post-translational modifications, such as phosphorylation and ubiquitination. Here, we discover that miR-927 is a novel regulator of wing size. Overexpression of miR-927 decreases wing size, which can be rescued by co-expressing miR-927-sponge. Next, we show that miR-927 stimulates apoptosis and suppresses the expression of Drosophila inhibitor of apoptosis protein 1, a well-known target gene of the Hippo pathway. Genetic epistatic analyses position miR-927 upstream of Yorkie (Yki) to modulate the Hippo pathway. In addition, there is a matching miR-927 seed site in the yki 3' untranslated region (3'-UTR), and we demonstrate that yki 3'-UTR is the direct target of miR-927. Ultimately, our study reveals that the targeting of yki by miR-927 to regulate the Hippo pathway is conserved in Helicoverpa armigera. Administration of miR-927 via star polycation (SPc) nanocarrier effectively inhibits wing development in H. armigera. Taken together, our findings uncover a novel mechanism by which Yki is silenced at the post-transcriptional level by miR-927, and provide a new perspective on pest management.

Abstract
KEY MESSAGE Gene silencing of BcDCL genes improves gray mold disease control in the cultivated strawberry. Gene silencing technology offers new opportunities to develop new formulations or new pathogen-resistant plants for reducing impacts of agricultural systems. Recent studies offered the proof of concept that the symptoms of gray mold can be reduced by downregulating Dicer-like 1 (DCL1) and 2 (DCL2) genes of Botrytis cinerea. In this study, we demonstrate that both solutions based on dsRNA topical treatment and in planta expression targeting BcDCL1 and BcDCL2 genes can be used to control the strawberry gray mold, the most harmful disease for different fruit crops. 50, 70 and 100 ng μL-1 of naked BcDCL1/2 dsRNA, sprayed on plants of Fragaria x ananassa cultivar Romina in the greenhouse, displayed significant reduction of susceptibility, compared to the negative controls, but to a lesser extent than the chemical fungicide. Three independent lines of Romina cultivar were confirmed for their stable expression of the hairpin gene construct that targets the Bc-DCL1 and 2 sequences (hp-Bc-DCL1/2), and for the production of hp construct-derived siRNAs, by qRT-PCR and Northern blot analyses. In vitro and in vivo detached leaves, and fruits from the hp-Bc-DCL1/2 lines showed significantly enhanced tolerance to this fungal pathogen compared to the control. This decreased susceptibility was correlated to the reduced fungal biomass and the downregulation of the Bc-DCL1 and 2 genes in B. cinerea. These results confirm the potential of both RNAi-based products and plants for protecting the cultivated strawberry from B. cinerea infection, reducing the impact of chemical pesticides on the environment and the health of consumers.

Abstract
Spray-induced gene silencing represents an eco-friendly approach for crop protection through the use of double-stranded RNA (dsRNA) to activate the RNA interference (RNAi) pathway, thereby silencing crucial genes in pathogens. The major challenges associated with dsRNA are its limited stability and poor cellular uptake, necessitating repeated applications for effective crop protection. In this study, RNA nanoparticles (NPs) were proposed as effectors in plants and pathogens by inducing the RNAi pathway and silencing gene expression. RNA structural motifs, such as hairpin-loop, kissing-loop, and tetra-U motifs, were used to link multiple siRNAs into a long, single-stranded RNA (lssRNA). The lssRNA, synthesized in Escherichia coli, self-assembled into stable RNA nanostructures via local base pairing. Comparative analyses between dsRNA and RNA NPs revealed that the latter displayed superior efficacy in inhibiting spore germination and mycelial growth of Botrytis cinerea. Moreover, RNA NPs had a more robust protective effect on plants against B. cinerea than did dsRNA. In addition, RNA squares are processed into expected siRNA in plants, thereby inhibiting the expression of the target gene. These findings suggest the potential of RNA NPs for use in plant disease control by providing a more efficient and specific alternative to dsRNA without requiring nanocarriers.

Challenges and Opportunities Arising from Host- Botrytis cinerea Interactions to Outline Novel and Sustainable Control Strategies: The Key Role of RNA Interference. Int J Mol Sci 2024; 25:6798.

Abstract
The necrotrophic plant pathogenic fungus Botrytis cinerea (Pers., 1794), the causative agent of gray mold disease, causes significant losses in agricultural production. Control of this fungal pathogen is quite difficult due to its wide host range and environmental persistence. Currently, the management of the disease is still mainly based on chemicals, which can have harmful effects not only on the environment and on human health but also because they favor the development of strains resistant to fungicides. The flexibility and plasticity of B. cinerea in challenging plant defense mechanisms and its ability to evolve strategies to escape chemicals require the development of new control strategies for successful disease management. In this review, some aspects of the host-pathogen interactions from which novel and sustainable control strategies could be developed (e.g., signaling pathways, molecules involved in plant immune mechanisms, hormones, post-transcriptional gene silencing) were analyzed. New biotechnological tools based on the use of RNA interference (RNAi) are emerging in the crop protection scenario as versatile, sustainable, effective, and environmentally friendly alternatives to the use of chemicals. RNAi-based fungicides are expected to be approved soon, although they will face several challenges before reaching the market.

Abstract
Trans-species RNA interference (RNAi) occurs naturally when small RNAs (sRNAs) silence genes in species different from their origin. This phenomenon has been observed between plants and various organisms including fungi, animals and other plant species. Understanding the mechanisms used in natural cases of trans-species RNAi, such as sRNA processing and movement, will enable more effective development of crop protection methods using host-induced gene silencing (HIGS). Recent progress has been made in understanding the mechanisms of cell-to-cell and long-distance movement of sRNAs within individual plants. This increased understanding of endogenous plant sRNA movement may be translatable to trans-species sRNA movement. Here, we review diverse cases of natural trans-species RNAi focusing on current theories regarding intercellular and long-distance sRNA movement. We also touch on trans-species sRNA evolution, highlighting its research potential and its role in improving the efficacy of HIGS.

Abstract
In view of the ongoing climate change and the ever-growing world population, novel agricultural solutions are required to ensure sustainable food supply. Microbials, natural substances, semiochemicals and double stranded RNAs (dsRNAs) are all considered potential low risk pesticides. DsRNAs function at the molecular level, targeting specific regions of specific genes of specific organisms, provided that they share a minimal sequence complementarity of approximately 20 nucleotides. Thus, dsRNAs may offer a great alternative to conventional chemicals in environmentally friendly pest control strategies. Any low-risk pesticide needs to be efficient and exhibit low toxicological potential and low environmental persistence. Having said that, in the current review, the mode of dsRNA action is explored and the parameters that need to be taken into consideration for the development of efficient dsRNA-based pesticides are highlighted. Moreover, since dsRNAs mode of action differs from those of synthetic pesticides, custom-made risk assessment schemes may be required and thus, critical issues related to the risk assessment of dsRNA pesticides are discussed here.

Abstract
Cross-kingdom small RNA trafficking between hosts and microbes modulates gene expression in the interacting partners during infection. However, whether other RNAs are also transferred is unclear. Here, we discover that host plant Arabidopsis thaliana delivers mRNAs via extracellular vesicles (EVs) into the fungal pathogen Botrytis cinerea. A fluorescent RNA aptamer reporter Broccoli system reveals host mRNAs in EVs and recipient fungal cells. Using translating ribosome affinity purification profiling and polysome analysis, we observe that delivered host mRNAs are translated in fungal cells. Ectopic expression of two transferred host mRNAs in B. cinerea shows that their proteins are detrimental to infection. Arabidopsis knockout mutants of the genes corresponding to these transferred mRNAs are more susceptible. Thus, plants have a strategy to reduce infection by transporting mRNAs into fungal cells. mRNAs transferred from plants to pathogenic fungi are translated to compromise infection, providing knowledge that helps combat crop diseases.
