文摘Mulberry is a fundamental component of the global sericulture industry,and its positive impact on our health and the environment cannot be overstated.However,the mulberry reference genomes reported previously remained unassembled or unplaced sequences.Here,we report the assembly and analysis of the telomere-to-telomere gap-free reference genome of the mulberry species,Morus notabilis,which has emerged as an important reference in mulberry gene function research and genetic improvement.The mulberry gap-free reference genome produced here provides an unprecedented opportunity for us to study the structure and function of centromeres.Our results revealed that all mulberry centromeric regions share conserved centromeric satellite repeats with different copies.Strikingly,we found that M.notabilis is a species with polycentric chromosomes and the only reported polycentric chromosome species up to now.We propose a compelling model that explains the formation mechanism of new centromeres and addresses the unsolved scientific question of the chromosome fusion-fission cycle in mulberry species.Our study sheds light on the functional genomics,chromosome evolution,and genetic improvement of mulberry species.

文摘The mirid bug Apolygus lucorum(Hemiptera:Miridae)is a polyphagous pest that affects a wide range of host plants.Its control remains challenging mainly due to its rapid reproduction,necessitating an understanding of sex pheromone communication.The recognition of sex pheromones is vital for courtship and mating behaviors,and is mediated by various chemosensory-associated proteins.Among these,sensory neuron membrane protein(SNMP),a CD36-related protein,is suggested to play crucial roles in detecting sex pheromones.In this study,we employed transcriptomic and genomic data from A.lucorum and phylogenetic approaches,and identified four putative SNMP genes(AlucSNMP1a,AlucSNMP1b,AlucSNMP2a,and AlucSNMP2b)with full open reading frames.Expression analysis revealed the ubiquitous presence of AlucSNMP transcripts in multiple tissues,with only AlucSNMP1a exhibiting male-biased expression in the antennae,suggesting its potential role in male chemosensation.Functional analysis using the Xenopus oocyte expression system,coupled with two-electrode voltage clamp recording,demonstrated that the co-expression of AlucSNMP1a with specific pheromone receptors(PRs)and the Odorant receptor co-receptor(Orco)significantly enhanced electrophysiological responses to sex pheromones compared to the co-expression of PRs and Orco alone.Moreover,the results indicated that the presence of AlucSNMP1a not only affected the responsiveness to sex pheromones but also influenced the kinetics(activation and inactivation)of the induced signals.In contrast,the co-expression of AlucSNMP1b with AlucPR/Orco complexes had no impact on the inward currents induced by two pheromone compounds.An examination of the selective pressures on SNMP1 genes across 20 species indicated strong purifying selection,implying potential functional conservation in various insects.These findings highlight the crucial role of AlucSNMP1a in the response to sex pheromones.

文摘There is an increasing need to reduce the use of pesticides to reduce their potential threat to food/environmental safety.At the same time,an increase in reactive oxygen species(ROS)induced by abiotic stresses in plants can lead to an increase in ROS in the plant and affect yield.In this paper,ROS-SPC was synthesised by two reactions and used as an efficient pesticide nanocarrier/adjuvant and scavenger of reactive oxygen species(ROS)in plants.By hydrophobic interaction,ROS-SPC spontaneously conjugated tofluazinam with a pesticide loading capacity(PLC)of 15.1%.Afterfluazinam was conjugated to ROS-SPC,the particle size offluazinam was reduced from 64.70 nm reduced to 19.82 nm,and the contact angle of pesticide droplets on plant leaves was significantly reduced from 59.44°to 26.76°.ROS-SPC as a carrier was tested to inhibit phytopathogenic fungi by 200%more than conventional delivery methods.In addition,we also learned that ROS-SPC with endocytosis capability can indeed remove reactive oxygen species from plants.Tests using HUVEC cells showed that ROS-SPC has low cytotoxicity within a reasonable range of applications,and ROS-SPC was tested to have low toxicity to pollinating bees.

文摘Ionogels have demonstrated substantial applications in smart wearable systems,soft robotics,and biomedical engineering due to the exceptional ionic conductivity and optical transparency.However,achieving ionogels with desirable mechanical properties,environmental stability,and multi-mode sensing remains challenging.Here,we propose a simple strategy for the fabrication of multifunctional silk fabric-based ionogels(BSFIGs).The resulting fabric ionogels exhibits superior mechanical properties,with high tensile strength(11.3 MPa)and work of fracture(2.53 MJ/m^(3)).And its work of fracture still has 1.42 MJ/m^(3)as the notch increased to 50%,indicating its crack growth insensitivity.These ionogels can be used as sensors for strain,temperature,and tactile multimode sensing,demonstrating a gauge factor of 1.19 and a temperature coefficient of resistance of3.17/℃^(-1).Furthermore,these ionogels can be used for the detection of different roughness and as touch screens.The ionogels also exhibit exceptional optical transmittance and environmental stability even at80℃.Our scalable fabrication process broadens the application potential of these multifunctional ionogels in diverse fields,from smart systems to extreme environments.

文摘Grapevine is one of the most economically important crops worldwide.However,the previous versions of the grapevine reference genome tipically consist of thousands of fragments with missing centromeres and telomeres,limiting the accessibility of the repetitive sequences,the centromeric and telomeric regions,and the study of inheritance of important agronomic traits in these regions.Here,we assembled a telomere-to-telomere(T2T)gap-free reference genome for the cultivar PN40024 using PacBio HiFi long reads.The T2T reference genome(PN_T2T)is 69 Mb longer with 9018 more genes identified than the 12X.v0 version.We annotated 67%repetitive sequences,19 centromeres and 36 telomeres,and incorporated gene annotations of previous versions into the PN_T2T assembly.We detected a total of 377 gene clusters,which showed associations with complex traits,such as aroma and disease resistance.Even though PN40024 derives from nine generations of selfing,we still found nine genomic hotspots of heterozygous sites associated with biological processes,such as the oxidation–reduction process and protein phosphorylation.The fully annotated complete reference genome therefore constitutes an important resource for grapevine genetic studies and breeding programs.

文摘Tetrandrine(TET),a natural bisbenzyl isoquinoline alkaloid extracted from Stephania tetrandra S.Moore,has diverse pharmacological effects.However,its effects on melanoma remain unclear.Cellular prolif-eration assays,multi-omics analyses,and xenograft models were used to determine the effect of TET on melanoma.The direct target of TET was identified using biotin-TET pull-down liquid chromatograph-mass spectrometry(LC-MS),cellular thermal shift assays,and isothermal titration calorimetry(ITC)analysis.Our findings revealed that TET treatment induced robust cellular autophagy depending on activating transcription factor 6(ATF6)-mediated endoplasmic reticulum(ER)stress.Simultaneously,it hindered autophagic flux by inducing cytoskeletal protein depolymerization in melanoma cells.TET treatment resulted in excessive accumulation of reactive oxygen species(Ros)and simultaneously triggered mitophagy.Sirtuin 5(SIRT5)was ultimately found to be a direct target of TET.Mechanistically,TET led to the degradation of SIRT5 via the ubiquitin(Ub)-26S proteasome system.SIRT5 knockdown induced ROS accumulation,whereas SIRT5 overexpression attenuated the TET-induced ROS accumula-tion and autophagy.Importantly,TET exhibited anti-cancer effects in xenograft models depending on SIRT5 expression.This study highlights the potential of TET as an antimelanoma agent that targets SIRT5.These findings provide a promising avenue for the use of TET in melanoma treatment and underscore its potential as a therapeutic candidate.

文摘The CRISPR-Cas13 system,an RNA-guided editing tool,has emerged as a highly efficient and stable RNA editing technique.Although the CRISPR-Cas13 system has been developed in several insect species,its application in lepidopterans has not yet been reported.In the present study,we evaluated the RNA cleavage activity of the CRISPR-Cas13 system in the silkworm(Bombyx mori),a model lepidopteran insect,both ex vivo and in vivo.We established two stable silkworm BmE cell lines expressing PspCas13b and CasRx,respectively.Further analysis demonstrated that both PspCas13b and CasRx effectively down-regulated the transcription of exogenouslyintroduced target and endogenous genes in these cell lines.In addition,we generated two transgenic silkworm strains,one expressing CasRx and the other expressing RNA-guided CRISPR RNA targeting Sex combs reduced(Scr).Further crossing experiments showed that CasRx induced a down-regulation of Scr transcription in silkworms,which impaired systemic growth of larvae.Overall,this study demonstrated that the CRISPR-Cas13RNA editing system works efficiently in the silkworm,providing a potential alternative approach for RNA manipulation in lepidopteran insects.

文摘The silk gland of the silkworm Bombyx mori serves as a valuable model for investigating the morphological structure and physiological functions of organs.Previous studies have demonstrated the notable regulatory role of let-7 microRNA in the silk gland,but its specific molecular mechanism remains to be elucidated across different segments of this organ.In this study,we further investigated the functional mechanism of let-7 in the middle silk gland(MSG).The MSG of a let-7 knockout strain was analyzed using a combined proteomic and metabolomic technique,revealing the enrichment of differential proteins and metabolites in the DNA synthesis and energy metabolism pathways.BmCentrin was identified as a novel target gene of let-7 in the MSG,and its downregulation inhibited the proliferation of BmN4-SID1 cells,which is exactly opposite to the role of let-7 in these cells.CRISPR/Cas9 genome editing and transgenic technologies were employed to manipulate BmCentrin in the MSG.Knockout of BmCentrin led to severe MSG atrophy,whereas the overexpression of BmCentrin resulted in beaded MSG.Further measurements of these knockout or overexpression strains revealed significant changes in the expression levels of sericin protein genes,the weight of the cocoon and the mechanical properties of the silk.Investigating the biological role of BmCentrin in the silk gland offers valuable insights for elucidating the molecular mechanisms by which let-7 controls silk gland development and silk protein synthesis in the silkworm.

文摘ATAD3A is a mitochondrial membrane protein belonging to the ATPase family that contains the AAA+domain.It is widely involved in mitochondrial metabolism,protein transport,cell growth,development and other important life processes.It has previously been reported that the deletion of ATAD3A causes growth and development defects in humans,mice and Caenorhabditis elegans.To delve into the mechanism underlying ATAD3A defects and their impact on development,we constructed a Bombyx mori ATAD3A(BmATAD3A)defect model in silkworm larvae.We aim to offer a reference for understanding ATAD3A genetic defects and elucidating the molecular regulatory mechanisms.The results showed that knockout of the BmATAD3A gene significantly affected the weight,survival rate,ATPase production and mitochondrial metabolism of individuals after 24 h of incubation.Combined metabolomics and transcriptomics analysis further demonstrated that BmATAD3A knockout inhibits amino acid biosynthesis through the regulation of mitochondrial ribosomal protein expression.Simultaneously,our findings indicate that BmATAD3A knockout impeded mitochondrial activity and ATPase synthesis and suppressed the mitochondrial oxidative phosphorylation pathway through B.mori mitochondrial ribosomal protein L11(BmmRpL11).These results provide novel insights into the molecular mechanisms involved in the inhibition of development caused by ATAD3A deficiency,offering a potential direction for targeted therapy in diseases associated with abnormal ATAD3A expression.

文摘To the Editor:Melanoma is the most aggressive and lethal cutaneous malignancy,with its incidence increasing annually.Surgical resection is effective for early-stage melanoma;however,therapeutic strategies for metastatic melanoma are limited by poor prognosis and adverse effects.[1]Our research team previously screened six compounds(Sanggenon C,Kuwanon A[KA],Kuwanon E,Moracin O,Moracin P,and 3′-geranyl-3-prenyl-2′,4′,5,7-tetrahydroxyflavone)with strong anti-melanoma effects from 28 compounds in Morus alba L.We focused on KA,whose structure is shown in Supplementary Figure 1A,http://links.lww.com/CM9/C458 with anti-inflammatory,antioxidant,and anticancer properties.[2,3]Its anti-tumor mechanisms in melanoma remain unclear.
文摘Gliomas represent the most common primary malignant intracranial tumors in adults.Despite recent advances in treatment,the prognosis of patients with glioblastoma remains poor.Epigenetic abnormalities,the hallmarks of various types of cancer,contribute to the dysregulated expression of cancer-related genes.Post-translational modification of histones plays a pivotal role in cancer development and progression by modulating gene transcription,chromatin remodeling,and nuclear structure.Therefore,further exploration of the molecular mechanisms of epigenetic regulation in gliomas and the identification of superior therapeutic targets are required.High-mobility group nucleosomal-binding domain 2(HMGN2)participates in the epigenetic regulation of genes through histone modification and exhibits significant differential expression between glioma and normal tissues.However,the effect of HMGN2 on gliomas and its underlying mechanisms remain unclear.This study aimed to elucidate these uncertainties by demonstrating that HMGN2 significantly promotes the proliferation of glioma cells.HMGN2 binds to histones and promotes the stability of H3K27ac acetylation in the cell division cycle 20(CDC20)promoter region,enhancing the transcriptional activity of CDC20 and increasing the proliferation of glioma cells.Moreover,we found that CDC20 expression was negatively correlated with the survival time of patients with glioma.These results suggest that targeting epigenetic regulation,such as the HMGN2/CDC20 axis,may provide a novel direction for the treatment of gliomas.

文摘Global public health faces substantial challenges from malignant tumors and infectious diseases.Vaccination provides an approach for treating and preventing these diseases.Oral vaccinations are particularly advantageous in disease treatment and prevention due to their non-invasive nature,high patient compliance,convenience,cost-effectiveness,and capacity to stimulate comprehensive and adaptive immune responses.However,the overwhelming majority of oral vaccines remain in experimental development,struggling with clinical and commercial translation due to their suboptimal efficacy.Thus,enhancing scientists’understanding of the interaction between vaccines and gastrointestinal immune system,creating antigen delivery systems suitable for the gut mucosal environment,developing more potent antigenic epitopes,and using personalized combination therapies are critical for advancing the next generation of oral vaccines.This article explores the fundamental principles and applications of current oral anti-tumor and anti-infective vaccines and discusses considerations necessary for designing future oral vaccines.
