The mechanistic target of rapamycin(m TOR) is a serinehreonine kinase that plays a pivotal role in cellular growth, proliferation, survival, and metabolism. In the central nervous system(CNS), the mTOR pathway regulates diverse aspects of neural development and function. Genetic mutations within the m TOR pathway lead to severe neurodevelopmental disorders, collectively known as “mTORopathies”(Crino, 2020). Dysfunctions of m TOR, including both its hyperactivation and hypoactivation, have also been implicated in a wide spectrum of other neurodevelopmental and neurodegenerative conditions, highlighting its importance in CNS health. 展开更多

The dental papilla(DP)is essential for the development of dentin and pulp.The extensive cellular heterogeneity within the DP is a critical factor underlying the complex and precise formation of dental structures during odontogenesis.However,the critical cell types within human DP that play essential role in tooth development and regeneration remain largely uncharacterized.In this study,we analyzed the heterogeneity of human DP cells using single-cell sequencing and identified Gliomedin(GLDN)+DP stem cells(DPSCs)were a group of progenitors at an early stage of tooth development and play a key role in the development of pulp and dentin.GLDN+DPSCs strategically accumulate in human DP tissue near the interface of the newly formed dentin or pulp.Functional assays demonstrated that GLDN+DPSCs exhibited enhanced self-renewal,migratory capacity,and odontogenic differentiation potential in vitro compared to GLDN-DPSCs.Moreover,GLDN+DPSCs effectively induce the migration and tube formation of endothelial cells,which are essential for tooth development.The ectopic dental pulp regeneration model confirmed that GLDN+DPSCs can regenerate a vascularized dental pulp structure with an odontoblast layer in vivo.Given their functional capabilities,this population of cells has been designated as GLDN+odontogenic stem cells(OSCs).Mechanistically,GLDN is essential for maintaining the phenotype and function of GLDN+OSCs through BMP5 signaling via autocrine and paracrine mechanisms.In conclusion,this study identifies a previously uncharacterized essential subpopulation of OSCs essential for dental pulp development and regeneration. 展开更多

The fruit of Amomum villosum is highly valued for its medicinal and edible properties.However,the fruit abscission rate is exceptionally high,resulting in low unit yield.To better understand the fruit growth and development,this study investigated the characteristic changes of fruits and the expression patterns of GA-related genes in both fruits and fruit stalks.Results revealed that it takes approximately 90 days for the ovary of A.villosum to reach maturity.Fruit growth pattern exhibited a slow-fast-slow trend,with the peak of fruit weight accumulation occurring between the 14 and 25 days after artificial pollination(DAP).Before the 27 DAP,significant changes were observed in the ovary,fruit color,pericarp thickness,and fruit thorn length.Additionally,ten candidate GA-related genes,including 1 GA13ox,1 GA20ox,1 GA3ox,2 GA2oxs,4 GID1cs,and 1 DELLA,were analyzed using bioinformatics tools.The GA-related genes in fruit and fruit stalk exhibited significant correlations with fruit growth/development and fruit dropping.Overall,the fruit growth and development law,and the expression patterns of GA-related genes provided a theoretical foundation for further functional study and the screening of candidate genes for potential applications in A.villosum. 展开更多

In the knowledge economy era,the rapid flow channels represented by high-speed rail(HSR)and online information flow promote cross-border development between cities.This study constructed a conceptual model of cross-border development from the perspective of flow space.Taking the Yangtze River Delta Region(YRDR),China,as a case study,we apply the Speaker-listener Label Propagation Algorithm(SLPA)to detect the heterogeneity patterns of cross-border development shaped by HSR flow and information flow in 2021.Results show that cross-border development among cities is more evident under information flows compared to HSR flow.Furthermore,intra-provincial cross-border development predominates under HSR flow,whereas inter-provincial cross-border development is more frequent under in-formation flow.Additionally,information flow leads to more shared or competitive nodes in cross-border development across different communities.In the future,leveraging these nodes'intermediary role will be the key to driving the next phase of regional integration.This research will enhance and broaden the theoretical frameworks for cross-border integrated development,flow space,and regional coordinated development. 展开更多

Knowledge of the maize pollen development stages at which high temperature(HT) stress leads to male sterility and yield loss would support targeted breeding strategies. In a cross between Zhengdan 958(HT-tolerant) and Xianyu 335(HT-sensitive) the contributions of maize traits to effective grain number(EGN) loss under HT stress were measured during pollen development stages, with loss increasing with the approach of flowering. Traits including pollen number per anther, total tassel spikelets, and pollen germination and shedding were the strongest contributors at various stages. The stage-specific vulnerabilities of maize tassels to HT stress suggest increasing pollen production before the tetrad stage and increasing pollen fertility and shedding during the microspore development stage. In the short term,increasing pollen developmental quality offers the greatest potential for reducing HT-caused EGN loss. 展开更多

The development of skeletal muscle are complicated processes involving genes responsible for proper muscle morphology,contractility,cell proliferation,differentiation,interactions,migration,and death.The three-dimensional chromatin architecture of skeletal muscle development has not been studied intensively although dynamic transcriptional regulation during differentiation of muscle cells is one of the most deeply studied processes.The RNA-seq was used to analyze the transcriptome pattern during chicken muscle development across 12 stages.Hi-C was used to build chromatin architectures during four representative stages.Ch IP-seq was conducted to identify enhancers and promoters in these four stages,which are occupied by histone H3K27ac and H3K4me3 peaks.Results show that large-scale genome architecture changes are mostly unidirectional,and coupled by complex on/off dynamic patterns of gene expression.Specifically,we observed 258.30 Mb of the genome undergoing A/B compartment switching.Notable alterations(316.57 Mb)of interaction frequencies within TADs were observed.Substantial aging-associated genes exhibited ascending connectivity with the compartment transition from repressive to active status during muscle development.Some muscle-related gene promoters that interacted with active enhancers during development,and some myopathy/aging-associated genes that were activated in aging muscle were founded.These results provide key insights into skeletal muscle development in vivo,and offer a valuable resource that allows in-depth functional characterization of candidate genes. 展开更多

Selenium(Se)serves as a trace element essential for the human body owing to its significant physiological functions and extensive pharmacological effects.The Se required by the human body is primarily obtained from soil-derived foods.This study revealed Se-rich soils covering a certain area and Se-rich edible wild mushrooms with high Se accumulation rates in Chuxiong,central Yunnan Province,China through a geochemical survey of soil quality.Furthermore,this study investigated the Se migration and transformation mechanisms in the soil-wild mushroom system,aiming to provide a scientific basis for the development and planning of Se-rich green foods in the study area.Using the geochemical data of samples collected from topsoils,deep soils,and wild mushrooms and their root soils in Nanhua County,Chuxiong,this study analyzed the Se contents in soils and wild mushrooms and their root soils and explored the mechanisms and influencing factors of Se enrichment in wild mushrooms.The results indicate that the topsoils in the study area exhibit Se contents ranging from 0.07 mg/kg to 0.95 mg/kg,with an arithmetic average of 0.25 mg/kg.The Se-rich soils cover an area of 356 km2,which accounts for 13.07% of the total topsoil area.The wild mushrooms in the study area display Se contents varying from 0.004 mg/kg to 47.10 mg/kg,with a median of 0.977 mg/kg.The analyses of Moran’s index and semivariogram indicate that the Se content distributions in both topsoils and deep soils in the study area exhibit distinct spatial structures.Specifically,the semivariogram model for the Se content in the deep soils emerges as a Gaussian model,and the Se content exhibits a nugget-to-sill ratio of 21.72%,suggesting that the Se content in deep soils is primarily influenced by structural factors such as parent materials.Se in the soils originates primarily from soil-forming parent rocks,with the origin of the Se-rich soils closely related to Triassic black shales,thin coal seams,and metamorphic rocks in the Ailao Mountain area.The wild mushrooms in the study area enjoy significantly higher Se content than other reported naturally Se-rich agricultural products,with a Se accumulation rate of up to 92.31%and an overall over-limit ratio of Pb and Cd of merely 11.54%,suggesting that the study area has substantial potential for the development of naturally Se-rich green foods.The wild mushrooms in the study area exhibit bioconcentration factors(BCFs)of Se ranging from 0.02 to 157.00(median:4.26),with Se bioavailability decreasing in the order of Boletus edulis,Boletus aereus,Leccinum nigrescens,Ramaria botrytoides,and Russula virescens.For the Se absorption and enrichment in the wild mushrooms,the primary controlling factor is identified as the wild mushroom species.Furthermore,they are significantly influenced by the Se content in soils but are minimally affected by the physicochemical indicators of soils. 展开更多

Ethylene,a pivotal gaseous phytohormone,regulates diverse processes in plant growth,development,and stress adaptation.In Arabidopsis(Arabidopsis thaliana),ethylene perception by endoplasmic reticulum localized receptors initiates a canonical signaling cascade involving CONSTITUTIVE TRIPLE RESPONSE 1(AtCTR1)and ETHYLENE INSENSITIVE 2(AtEIN2).This pathway culminates in nuclear translocation of AtEIN2-CEND and activation of the transcription factor AtEIN3/EIN3-LIKE1(AtEIL1).Rice employs conserved(OsEIN2,OsCTR2,OsEIL1/2)and unique(Mao Huzi 3[MHZ3],MHZ11,MHZ1)components for ethylene signaling,reflecting adaptations to semi-aquatic environments.Ethylene regulates developmental processes including seed germination,apical hook formation,root architecture,flowering,and senescence,often via intricate crosstalk with auxin,abscisic acid,jasmonic acid,gibberellins,and brassinosteroids.Ethylene signaling also influences rice yield-related traits such as grain filling,grain size,and starch biosynthesis.Moreover,ethylene modulates responses to abiotic stresses(such as submergence,hypoxia,salinity,drought,and temperature fluctuations)and nutrient imbalances.This review synthesizes current understanding of ethylene signaling and its functions,focusing on the model dicot Arabidopsis and the monocot rice(Oryza sativa).It highlights conserved and diverged mechanisms,underscoring ethylene's potential as a target for enhancing crop resilience and productivity in changing environments. 展开更多

Chloroplast gene expression relies on nucleus-encoded factors for RNA metabolic processing,but the mechanisms under cold stress remain poorly understood.In this study,we isolated and characterized a foxtail millet(Setaria italica)mutant,temperature-sensitive chlorophyll-deficient(sitcd1),which exhibited reduced chlorophyll content and abnormal chloroplasts,resulting in an albino phenotype during early leaf development at low temperatures(20℃during the day and 18℃at night,L20/D18).Map-based cloning revealed that SiTCD1 encodes a P-type PPR protein localized in chloroplasts.In sitcd1 background,transgenic lines overexpressing SiTCD1 had nearly normal green leaves under L20/D18 conditions.SiTCD1 was especially expressed in the earlier development of leaves at low temperatures.In addition,SiTCD1 bound directly to the plastid gene atpF in vitro,so it might participate in the splicing of plastid gene atpF at low temperatures.RNAseq results indicated that the expression of genes related to metabolism(such as porphyrin,chlorophyll and glutathione metabolism),which require ATP for energy,was down-regulated in sitcd1,resulting in reductions in chlorophyll content,reduced glutathione(GSH),and its redox couple(GSH/oxidized glutathione(GSSG))at low temperatures.As sitcd1 exhibited greater sensitivity at the bud bursting stage than germination or the seedling stage under cold stress,we identified two haplotypes of SiTCD1(SiTCD1Hap1 and SiTCD1Hap2)in 195 accessions,and found that accessions carrying the SiTCD1Hap2 allele were more tolerant to cold stress than those with the SiTCD1Hap1 allele at the bud bursting stage.In summary,our results suggest that Si TCD1 is essential for early chloroplast development at low temperatures in foxtail millet. 展开更多

The HD-ZIP gene family,a group of plant-specific transcription factors,plays pivotal regulatory roles in various aspects of plant growth and development.Accumulating evidence has demonstrated the extensive involvement of HD-ZIP members in regulating reproductive developmental processes.This review systematically summarizes both the structural characteristics of the four HD-ZIP subfamilies(Ⅰ-Ⅳ)and their distinct regulatory roles in plant reproductive development.Recent studies reveal that a conserved HD-ZIPⅠclade serves as a core regulator of key reproductive processes,ranging from spike development in monocots(e.g.,barley Vrs1 and maize GT1)to sex determination in dicots(e.g.,cucumber CmHB40 and persimmon MeGI).Meanwhile,members of other subfamilies(HD-ZIPⅡ-Ⅳ)contribute significantly to diverse reproductive processes including pistil development,floral organ formation,and anther development,among others.This review provides a comprehensive synthesis of HD-ZIP subfamily functions in reproductive development,integrating current knowledge while highlighting critical research gaps.These insights aim to provide theoretical foundations for functional characterization and potential applications of HDZIP reproductive regulators,while advancing our understanding of transcriptional regulation mechanisms in plant reproductive development. 展开更多

The Qilian Mountains(QLMs),a critical transitional zone between China's cold and arid regions,serve as a vital ecological security barrier and water conservation area.Their sustainable development is essential for achieving regional ecological civilization and coordinated socio-economic progress.This study,grounded in ecological carrying capacity theory,established a comprehensive evaluation index system for the QLMs,delineated ecological functional zones using natural and socioeconomic data from 2001–2020,and then explored six sustainable development modes.Results revealed significant spatial heterogeneity in ecological carrying capacity in QLMs from 2001 to 2020,based on which ecological red line(32.02%),yellow line(40.30%),and green line(27.68%)zones were designated.The red,yellow,and green line zones correspond to priority conservation,conservation-development coordination,and appropriate development areas,respectively.For different zones,six differentiated development modes were proposed,the ecological conservation mode emphasized strict protection and systematic restoration to secure key ecological functions.The ecological compensation mode used institutionalized compensation to offset conservation costs and improve both protection performance and livelihoods.The ecological tourism mode leveraged natural and cultural resources to generate green income.The aboriginal integration mode strengthened resilience through livelihood transition and cultural continuity.The community co-management mode enhanced local governance through shared rights,responsibilities,and benefits.The social participation mode reinforced regional governance via multi-actor collaboration and resource integration.Overall,ecological red line zones emphasized conservation and compensation,yellow line zones balanced social participation,while green line zones integrated all six modes.This study provided actionable solutions to resolve the conflict between ecological protection and economic development in the QLMs,and offered a replicable‘assessment-zoning-modeling'framework for sustainable development in other ecologically fragile and barrier regions in China. 展开更多

Objectives This study aimed to develop a competency-oriented ecological education model and evaluate the feasibility and preliminary outcomes of its implementation for enhancing evidence-based practice competencies among undergraduate nursing students.Methods An ecological education model was developed based on educational ecology theory and the input–environment–output(IEO)theoretical framework,and implemented from 2019 to 2024.The model integrated three core components:a four-year progressive competency development pathway(ranging from evidence-based thinking in year one to comprehensive practice application in year four);a three-tier ecological environment(comprising physical,classroom,and practice environments that incorporates six best practice spotlight organization guidelines into eight core courses);and multidimensional practice platforms,including health science communication and guideline translation.The reform was conducted at a nursing school of a double first-class university in Beijing,China.A naturalistic longitudinal cohort design was employed,which included 1,223 undergraduate nursing students at baseline(2019,pre-reform)and 1,237 at post-implementation(2024).A convergent parallel mixed-methods approach was used to evaluate the implementation outcomes.Quantitative data on academic performance and innovation outcomes were collected at both time points,baseline and post-implementation.Semi-structured interviews with 18 students were conducted to supplement the exploration of their learning experiences.Results Academic engagement increased from 78.5%to 97.3%,evidence-based graduation theses rose from 18.6%to 30.0%,and innovation and entrepreneurship projects increased from 40 to 150.Qualitative analysis revealed four themes and twelve subthemes,revealing enhanced critical appraisal skills(88.9%),evidence synthesis capabilities(94.4%),and professional confidence(83.3%)among students.Integrated mixed-methods analysis revealed stage-specific characteristics across academic years:a complementarity pattern in Year 1(foundational awareness building),a convergence pattern in Years 2–3(systematic competency construction),an expansion pattern during the Year 3 transition(role adaptation challenges),and a convergence pattern in Year 4(comprehensive transformation and professional confidence enhancement).Conclusions This feasibility study demonstrated that the ecological education model could be successfully implemented in undergraduate nursing education with promising preliminary outcomes.This study provides an initial framework for nursing education innovation and establishes foundational evidence warranting future rigorous controlled studies to examine the model’s effectiveness. 展开更多

Peanut(Arachis hypogaea L.)serves as a vital oilseed and food crop worldwide.Embryo abortion reduces seed set in peanut and significantly limits yields,but the mechanisms responsible have remained unclear.Here,we examined an ethyl methanesulfonate(EMS)-induced peanut mutant exhibiting early embryo abortion and a partially single-seeded pod phenotype.Cytological analysis indicated that seed abortion in the mutant begins at the proembryo stage,7 d after flowering,with noticeable degeneration by 3 d after peg penetration into the soil(DAP),culminating in complete arrest by 10 DAP.Transcriptomic analysis identified 8778 differentially expressed genes(DEGs)during the transition from aerial to subterranean peg development in the mutant.These DEGs were significantly enriched for pathways such as MAPK signaling,auxin biosynthesis and transport,and calcium transport.Notably,we identified a premature stop codon mutation(C>T)in AhZAR1-4 of the mutant;this gene encodes a leucine-rich repeat receptor-like kinase.The mutation resulted in the truncation of the kinase and transmembrane domains of AhZAR1-4,leading to a loss of membrane localization and protein function.In yeast two-hybrid screening,AhZAR1-4 interacted with both AhIAA31 and AhBSK2.Heterologous overexpression of AhZAR1-4wtsuccessfully rescued the seed-abortion phenotype of the Arabidopsis thaliana atzar1-4 mutant and increased seed size,whereas AhZAR1-4mut expression did not.These findings identify AhZAR1-4 as a crucial regulator of seed development in peanut,making it a promising genetic target for improving pod yield and seed setting rate. 展开更多

Anther is a key male reproductive organ that is essential for the plant life cycle,from the sporophyte to the gametophyte generation.To explore the isoform-level transcriptional landscape of developing anthers in maize(Zea mays L.),we analyzed Iso-Seq data from anthers collected at 10 developmental stages,together with strand-specific RNA-seq,CAGE-seq,and PAS-seq data.Of the 152,026 high-confidence full-length isoforms identified,68.8%have not been described;these include 22,365 isoforms that originate from previously unannotated loci and 82,167 novel isoforms that originate from annotated protein-coding genes.Using our newly developed strategy to detect dynamic expression patterns of isoforms,we identify 13,899 differentially variable regions(DVRs);surprisingly,1275 genes contain more than two DVRs,revealing highly efficient utilization of limited genic regions.We identify 7876 long non-coding RNAs(lncRNAs)from 4098 loci,most of which were preferentially expressed during cell differentiation and meiosis.We also detected 371 long-range interactions involving intergenic lncRNAs(lincRNAs);interestingly,243 were lincRNA-gene ones,and the interacting genes were highly expressed in anthers,suggesting that many potential lncRNA regulators of key genes are required for anther development.This study provides valuable resources and fundamental information for studying the essential transcripts of key genes during anther development. 展开更多

Chromatin remodeling plays an essential role in plant reproductive development.Our previous studies demonstrated that CHR721,a SWI/SNF-family chromatin remodeler,is essential for reproductive development in rice,as evidenced by a chr721 mutant exhibiting unrepaired DNA lesions during late meiosis and subsequent cell cycle arrest,ultimately causing sterility.Here,we observed defective pollen exine,anther epidermis,tapetal degeneration,and aberrant nutrient metabolism in the chr721 mutant,particularly in lipid mobilization.Lipid species essential for anther development,including phosphatidylcholine(PC),lysophosphatidylcholine(LPC),and phosphatidylethanolamine(PE),exhibited reduced accumulation in the mutant compared to the WT.We established the central regulatory role of CHR721-mediated transcription during anther development.RNA-seq profiling of the mutant uncovered many differentially expressed genes(DEGs)at the late-meiotic,uninucleate,and binucleate stages,revealing progressive transcriptional perturbations.Functional enrichment analysis(GO and KEGG)revealed significant associations with lipid metabolism-related pathways and biological processes necessary for anther development,including tapetal development and regulation of programmed cell death(PCD).These transcriptional regulations were consistent with the morphological characterization and lipidomic analysis of the anthers in the WT and mutant.All these results and previous studies suggest that CHR721 regulates transcription by influencing the chromatin status and provide novel insight into the transcriptional function of CHR721 in anther development in rice. 展开更多
