Expérience de préservation de perches et piquets à usage rural en République Malgache
Authors: Bedel J. , Rakotovao Georges , Thiel Jean
Published: October 2024

Madagascar a un besoin potentiel considérable de perches et de piquets pour les clôtures, les poteaux télégraphiques, les poteaux de câbles électriques, etc. La meilleure source d'approvisionnement se trouve dans les plantations d'eucalyptus et, dans une moindre mesure, de pins. La durabilité naturelle de ces essences est médiocre, et elles nécessitent donc un traitement de préservation approfondi. Le procédé dit de la « Boucherie » peut apporter une solution bien adaptée aux conditions de Madagascar, car il correspond à un équilibre satisfaisant entre le coût, la simplicité et l'efficacité. Les auteurs soulignent l'intérêt de ce procédé et présentent les résultats obtenus au cours de treize années d'expérimentation. Ces recherches ont permis d'améliorer la méthode en mettant au point un tampon simplifié qui est décrit en détail. Le traitement alterné des deux extrémités a fait l'objet d'expériences concluantes ; il confère aux perches une protection adaptée à leurs conditions d'utilisation, et dans des conditions beaucoup plus satisfaisantes que le procédé classique. Dans certaines conditions, l'eucalyptus peut être traité à sec et il est proposé d'effectuer des recherches sur cette méthode. La méthode dite du "tonneau" est également décrite ; elle est applicable sur de courtes longueurs et dans de très bonnes conditions de ventilation. En conclusion, les auteurs abordent la question de la vulgarisation des résultats de la recherche et suggèrent la création d'un centre technique qui passerait des contrats avec des partenaires, permettrait la diffusion de l’information, organiserait des démonstrations, formerait du personnel, favoriserait l'installation de stations de traitement utilisant des méthodes rustiques et maintiendrait un contact étroit avec les recherches en cours.

Pénzügyi biztonság Magyarországon: a 2023-as OECD-felmérés eredményeinek kettős nézőpontú elemzése
Authors: Németh Erzsébet , Kálmán Botond Géza , Malatyinszki Szilárd
Published: October 2024

Jelen tanulmány a magyar felnőtt lakosság pénzügyi biztonságát vizsgálja. A kutatás alapját a Gazdasági Együttműködési és Fejlesztési Szervezet (OECD) által rendszeresen elvégzett felmérések képezik, amelyek a tagállamok lakosságának pénzügyi ismereteit, viselkedését és attitűdjeit mérik. Cikkünk a pénzügyi biztonság kérdését a legutóbbi, 2023. évi magyarországi vizsgálat alapján két nézőpontból elemzi: egyrészt a válaszadók biztonságérzetét, másrészt tényleges biztonságukat mutatja be. Az OECD kérdőíve a válaszadók több demográfiai jellemzőjét is felméri. Kutatásunk szintén elsősorban az ezek alapján képezhető csoportokat hasonlítja össze statisztikai módszerek alkalmazásával. Az eredmények számos új, a korábbi szakirodalomtól sok esetben eltérő megállapítással árnyalják a magyar felnőttek vélt és valós biztonságáról alkotott képet. Az új eredmények segíthetik a lakosság legsérülékenyebb csoportjainak azonosítását és a számukra nyújtott gyakorlati segítség módjainak kidolgozását.

Authors: Molnár László , Nagy Szabolcs , Papp Adrienn
Published: October 2024

Az elmúlt évtizedek gyors technológiai fejlődése a pénzügyi szolgáltatások átalakulásához és digitalizációjához vezetett, ami a neobankok megjelenését, illetve gombaszerű elterjedését eredményezte. Az ilyen típusú, fiók nélküli bankok által kínált szolgáltatások elterjedésének kulcsfontosságú sikertényezője a fogyasztói elfogadottság mértéke. Kutatásunk célja, hogy megértsük a potenciális és a jelenlegi neobank-felhasználók egyéni döntéshozatali folyamatát. Tanulmányunkban igyekszünk feltárni az ügyfelek neobank-szolgáltatások igénybevételi szándékát befolyásoló tényezők közötti összefüggéseket, amihez a széles körben használt technológiaelfogadási modellt (Technology Acceptance Model, TAM) alkalmazzuk, kibővítve egy új tényezővel, a bizalommal. A kutatási kérdések megválaszolása érdekében 2022-ben online kérdőíves felmérést végeztünk Magyarországon. A 475 válaszadóból álló mintát strukturálisegyenlet-modellezéssel (Structural Equation Modeling, SEM) vizsgáltuk, és eredményeink azt mutatják, hogy a használati szándékot közvetlenül befolyásolja a használathoz való hozzáállás, amelyet pedig pozitívan befolyásol a bizalom, az észlelt hasznosság és a használat észlelt könnyűsége. Eredményeink alapján azt javasoljuk, hogy a neobankok a szolgáltatásaik iránti pozitív attitűdök kialakítására összpontosítsanak, a bizalom, a megbízhatóság, a könnyű használhatóság és a szolgáltatásaik hasznosságának hangsúlyozásával.

From Theory to Practice: The Deployment of Intersectionality in International Human Rights Policy
Authors: Petričušić Antonija
Published: October 2024

International and national human rights legal and policy frameworks have traditionally relied on addressing discrimination through a single-axis angle, identifying and addressing single grounds in cases of discrimination. By focusing predominantly on individual dimensions of discrimination, they often neglected to acknowledge the systemic and historical dimensions of discrimination which continue to shape contemporary social inequalities and hierarchies. A concept of intersectional discrimination, although now widely accepted, has not yet been consistently reflected in the legal and policy documents of international human rights organizations. This article examines the extent to which the monitoring mechanisms of international human rights instruments take an intersectional approach to improve policy outcomes and tackle the structural roots of inequality that pervade societies around the world and prevent the achievement of substantive equality for all.

Физическое обоснование схемы дискретизации при моделировании глубокого проплавления металлов в лазерных и родственных технологиях
Authors: Seidgazov Rinad Dzhaferovich , Mirzade Fikret Khansuvarovich
Published: October 2024

Анализируется способность численных моделей адекватно воспроизводить гидродинамические процессы в режиме глубокого проплавления металлов в лазерных и электроннолучевых сварочных и родственных технологиях. Отмечается противоречивый характер выводов разных моделей об относительных вкладах термокапиллярного и абляционного механизмов в образовании глубокой каверны. Решение данной проблемы предполагает приведение расчетных результатов модели в соответствие с экспериментальными данными, согласно которым в технологических условиях основной вклад в формирование каверны вносит термокапиллярный механизм при незначительном испарении. Искажение соотношения этих вкладов является следствием неадекватного воспроизведения специфических особенностей термокапиллярного механизма в режиме глубокого проплавления. Причиной является выбор шага расчетной сетки без учета реального масштаба термокапиллярного потока в режиме глубокого проплавления. Предложена методика выбора физически обоснованного пространственного и временного шага расчетной сетки. Выполнены оценки для рекомендуемой дискретизации задачи при характерных размерах пятна фокусировки, используемых в технологиях лазерной сварки и аддитивного производства селективным лазерным плавлением. Проведено сравнение рекомендуемого шага расчетной сетки с обычно применяемой дискретизацией.

Authors: Ferdinand David , Hartanti Lanny
Published: October 2024

SARS-CoV-2 virus can cause Coronavirus disease 2019 (COVID-19). The interaction between spike protein and ACE2 receptor causes virus entry into the cells. The aim of this study was to review the utilization of nutraceutical and phytochemical agents to inhibit the interaction of spike protein envelope SARS-CoV-2 virus and ACE2 receptor. The data literature was retrieved from several databases such as Google scholar, Science direct, and PubMed. This study was conducted from September-October 2020. The review process was conducted based on PRISMA Guidelines.The results showed that nutraceuticals such as tuna peptides (EEAGGATAAQIEM), nisin, teicoplanin, zinc, propolis, Ganoderma lucidum, brown algae, and lectin have the potential to inhibit the interaction of spike protein SARS-CoV-2 virus and ACE2 receptor. Phytochemical compounds such as curcumin, luteolin, EGCG, hesperidin, resveratrol, saikosaponin, nicotianamine, procyanidin and the others also have the same. From this study, it can be concluded that nutraceuticals and phytochemical agents have potential benefits in COVID-19 treatment based on in silico study. However, we need further studies based on in vitro experiments and in vivo to ensure the effectivity of those nutraceutical agents.

Transmissible Spongiform Encephalopathies Prion Proteins: A Systematic Review
Authors: Poddar Anirban , Kundu T. N. , Ray Manaly Sinha , Maji Rituparna
Published: October 2024

Prion proteins (PrPc) have been implicated as the causative agent of “Transmissible Spongiform Encephalopathies” (TSE). Apart from this devilish role, prions also have a bright facet of their own and their identity holds much more than just being a pathogenic entity. Role of prions as scaffolding proteins for ligand binding and signal transduction has been reported by several researchers. Role of prions in nerve impulse transmission at neuronal junctions, glyapse and gap junctions have been reported. Prion mediated regulation of calcium ion flux and redox status in turn regulates many major cellular functions. In this review we have focussed mainly on the physiological aspects of prion function apart from its pathological role in TSE. Role of prions in mediation of neuropathic pain, neuroinflammatory diseases and chronic headache has been reported by few researchers. In this review we have tried to correlate such effects of prions and also discuss various therapeutic targets for various diseases influenced by prions.

The Fall armyworm (FAW) Spodoptera frugiperda, native to the Americas, is an important invasive and polyphagous pest threatening cereal production. Abiotic and biotic factors, including climatic uncertainty and insect pests like S. frugiperda, pose threats. Detected in East Africa in 2016 and reported in Nawalpur, Nepal, on May 9, 2019, FAW has led to a 34% decline in maize yields. Studying FAW's biology and morphometrics is crucial for understanding its habitat and ecology, essential prerequisites for adopting integrated management strategies. Biological parameters such as incubation period, larval and pupal duration, pre-oviposition and, oviposition periods, male and female adult longevity, larval and pupal mortality, sex ratio (male: female), and morphometrics of egg, larvae, pupa, and adult were measured. The incubation period (2-3 days), larval and pupal periods (13-18 and 9-12 days) with overall life duration (31-45 days) were recorded in maize. Head capsule width of the first, second, third, fourth, fifth, and sixth instar were recorded as 0.52±0.05, 0.73±0.05, 1.1±0.05, 1.74±0.12, 2.04±0.15, and 2.91±0.23 mm respectively. Mean body length of different larval instars were recorded as 3.33±0.26, 6.92±1.07, 13.11±1.45, 16.82±1.57, 28.68±1.75, and 34.56±1.99 mm for the first, second, third, fourth, fifth, and sixth instar respectively.
De la cultura como organismo vivo

El comprender el desarrollo de las culturas a partir de una analogía fisiológica, en que la historia resulta semejante a la de un organismo vivo, implica tanto la continuidad como la desaparición del cuerpo social. Si bien se trata de un ciclo vital que experimenta un principio y un fin, no hay una barrera estricta entre uno y otro. Es decir, tras la cúspide de la civilización deviene una nueva barbarie y este retornar o consiste en repetir el ciclo sobre los cimientos del anterior o, simplemente, en el final.

Tentativa para perseguir personajes kafkianos en el siglo XXI
Authors: Baca Muñoz Omar
Published: October 2024

Kafka fue usado –sobreexplotado, según Susan Sontag– como el gran mito para dotar de imágenes y expresiones al siglo XX. A golpes de hermenéutica, filósofos, críticos y otros intérpretes lo transformaron en un profeta de todos los males que comenzaron mientras él vivía y que se agravaron después de su muerte: el antisemitismo, los campos de concentración, la burocracia, el control estatal, el capitalismo, el totalitarismo... Estas lecturas le proveyeron permanencia, canonización y un lugar único en la cultura occidental. También aquellas que lo reducían a un creador de parábolas metafísicas.

Authors: Vosoughi Fardis , Menbari Oskouie Iman , Rahimdoost Nazanin , Kasaeian Amir , Sherafat Vaziri Arash
Published: October 2024

Background:

The interobserver and intraobserver reliability of various tibial plateau fracture (TPF) classifications has been examined in recent literature using radiography, computed tomography, and magnetic resonance imaging. The question remains as to which classification system provides the highest reliability. In this systematic review, we are going to evaluate the overall interobserver and intraobserver reliability of various TPF classifications in different imaging modalities.

Methods:

We conducted a systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. In February 2023, predefined terms were used for database search (Embase, PubMed, Scopus, Cochrane, and Web of Science). Meta-analysis of intrarater and inter-rater kappa coefficients was performed for each of the classifications in each modality.

Results:

Thirty-four studies were included in this review. Schatzker's classification was more frequently used than others. It had a better intrarater kappa coefficient than the Hohl and Moore and Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association (AO/OTA) classifications in radiography (κ = 0.72, 95% confidence interval [CI] = 0.67-0.76, p < 0.01). The Schatzker and AO/OTA classifications had similar inter-rater reliability in the radiography modality (κ = 0.53, 95% CI = 0.51-0.54, p < 0.01; κ = 0.53, 95% CI = 0.5-0.55, p < 0.01; respectively). In 3-dimensional computed tomography, the Luo classification system showed the highest intrarater (κ = 0.85, 95% CI = 0.35-0.66) and inter-rater (κ = 0.77, 95% CI = 0.73-0.81) kappa coefficients.

Conclusion:

Three-column classification proposed by Luo et al. was able to reach the highest degree and was the only classification with near-excellent inter-rater reliability.
Comite diversion numerical model study
Authors: McAlpin Tate , McKnight C. , Emiren Anthony , Brown Gary
Published: October 2024

The Comite River diversion project is designed to reduce flooding along the Comite and Amite Rivers during flood events by diverting flow from the Comite River into the Mississippi River above Baton Rouge, Louisiana. The flow is diverted from the Comite River along a diversion canal to the Lilly Bayou Control structure. This structure allows the Comite River flow to enter the Mississippi River floodplain. A numerical model was created to evaluate the impacts associated with this addition of water to the Mississippi River. A 2D Adaptive Hydraulics numerical model was created to quantify the system impacts associated with the diverted flow in conjunction with possible system modifications to control the flow pathway. The impact of the diversion was determined to be heavily dependent on the flow and stage of the Mississippi River. At higher stages and flows, the flow diverted by the Lilly Bayou Control structure is negligible in relation to the much larger Mississippi River flow and therefore the impacts of the added flow are significantly less than at lower Mississippi River stages. At lower Mississippi River flows and stages, the added flow from the Lilly Bayou Control structure has a larger impact on the inundation due to the larger relative amount of diverted flow in relation to the Mississippi River. Ultimately, the diverted Comite River flow has some incremental increase in water levels at all Mississippi River stages.
A Novel Hybrid Physics/Data-Driven Model for Fractured Reservoir Simulation
Authors: Aslam Billal , Yan Bicheng , Lie Knut-Andreas , Krogstad Stein , Møyner Olav , He Xupeng
Published: October 2024

Fractured reservoir simulation plays a crucial role in understanding various subsurface geo-energy recovery and storage processes, including shale gas/oil extraction, enhanced geothermal systems, and CO2 sequestration in basaltic rocks. However, such simulations often entail significant computational expenses due to the high contrast in permeability and pore volume (PV) between matrix and fractures. To address this challenge, we introduce a reduced-order model (ROM) tailored for fractured reservoir simulation that offers flexible fracture representations by generating coarse matrix nodes based on reservoir outlines and adding extra diagonal connections between unconnected matrix nodes, whose corresponding volumes are intersected by fractures. This approach avoids the need for additional fracture nodes, effectively reducing computational costs. Dimensionality reduction methods, such as principal component analysis (PCA), are used to give quality priors for sampling matrix transmissibility and PV arrays. Tuning to well observation data, such as flow rates and bottomhole pressures (BHPs), is achieved through a gradient-based optimization method within a general automatic-differentiable simulator framework. Our results demonstrate robust calibration using synthetic well observation data from a fine-scale reference simulation model. Incorporating dominant flow physics, such as water breakthrough, from observation data improves history-matching (HM) convergence and prediction accuracy. Additionally, PCA for parameterization enhances the convergence rate of model calibration compared with random initialization. Calibrated transmissibilities align with high-connectivity regions from the fine-scale reference model, rendering the model interpretable in terms of reservoir connectivity or geology. This feature enables our method to be used effectively for reservoir HM and optimization using field observation data.

Machine learning has proven valuable in developing PPG-based approaches for blood pressure (BP) estimation, with many holding some promise for cuff-less BP assessment. Still, they depend on accurate and robust fiducial point detection algorithms to extract several features from collected signals. The present study explores the usefulness of several non-fiducial features of the PPG signal and its derivatives in estimating BP by combining well-known feature selection methods and machine learning techniques. We collected PPG recordings from 56 participants and computed fifty-seven non-fiducial features, including statistical indexes and energy operators. After implementing three feature selection algorithms (i.e., F-test, mRMR, and ReliefF), the most relevant features were employed to train four learning regression model families: linear regressions (LR), regression trees (RT), support vector regressions (SVR), and Gaussian process regressions (GPR). The abovementioned feature selection methods produced different optimal feature subsets for SBP and DBP estimation, with the Matern 5/2 and the rational quadratic GPR models providing the best predictions when combined with ReliefF (MAE = 0.44, MSE = 0.61, and RMSE = 0.78 mmHg for SBP; MAE = 0.31, MSE = 0.40, and RMSE = 0.63 mmHg for DBP). Furthermore, each model utilizes only fifteen features, many of which are relatively easy to compute, thus becoming suitable for computationally constrained hardware. We highlight the need for implementing feature selection algorithms exhaustively, as the most relevant PPG-based features for SBP estimation might not have the same weight for DBP prediction and vice versa.

OBJECTIVE
To understand the prevalence of myopia and its influencing factors among primary and secondary school students in Shihezi City to provide a scientific basis for future interventions for improving, safeguarding and promoting the visual health of primary and secondary school students.
METHODS
The population comprised primary and secondary school students in Shihezi City. A stratified random sampling method was used to determine the research school, which was then stratified by grade. Two classes were randomly selected as sample classes for each grade. All students received a vision examination. Students of grade ≥ 4 completed the investigation of myopia-related influencing factors using questionnaires.
RESULTS
A total of 6732 people were surveyed in this study, and 6092 people were finally included (participation rate: 90.49%), of which boys represented 51.10%. The overall prevalence of myopia was 59.55%. The prevalence of myopia in urban areas was 68.17%, while in rural areas was 42.42%, and the difference was statistically significant. Being female students, having myopic parents, close-distance reading or writing, and receiving education at an older age were risk factors for myopia, while attending school in a rural area was a protective factor against myopia. Additionally, factors influencing myopia varied among subgroups, but parental myopia appeared in almost every subgroup.
CONCLUSION
Myopia rates in Shihezi City are higher than the national average and gradually increase with school age. In addition to inherent factors (gender, increasing school age and genetic factors), myopia prevention should include proper sitting, eye habits and health promotion.
All-cause deaths and North Atlantic accumulated cyclone energy: understanding the relationship based on county-level income and education levels
Authors: Majeed Haris , Zuberi Daniyal
Published: October 2024

North Atlantic hurricanes have intensified in the past decades, resulting in excess deaths especially among lower-income populations who tend to have elevated mortality rates in coastal regions. Yet the effects of hurricane intensity on mortality rates by income and education levels has not been understood. This population-based study used the North Atlantic accumulated cyclone energy (ACE) index to examine the effects on all-cause mortality (20–84 years) by county-level income and college education level stratification (high and low) in the southeastern United States from 2014–2022. We found that an extreme (≥ 160×104 kt2) ACE period (in comparison to normal ACE period) was associated with all-cause mortality by a rate ratio (RR) of 1.056 (P < 0.001) times. The relationship between ACE index and all-cause mortality was found to be linear. Furthermore, when stratified by income and education levels, only those counties with high-income and high-education were found to have significant associations between above (≥ 126×104 kt2) ACE (in comparison to normal ACE period) and mortality (RR 1.056, P = 0.0008). All other combinations of income and education levels were found to have insignificant associations with mortality during above normal intensity hurricane years. This appears to be explained by the geographic concentration of high income and high education counties along the coasts as compared to the more inland location of low income and low education countries, thus increasing the exposure to impacts of hurricane events. This is the first study to denote that hurricane effects vary based on a combination of income and education levels. Further investigations are needed to identify the effects of hurricanes on cause-specific events based on income and education levels in the United States.
Improving the hydrophilic microenvironment surrounding the catalytic site of fructosyltransferase enhances its catalytic ability

Published: October 2024

The hydrophilic microenvironment surrounding the active site of an enzyme may affect its catalytic activity. In the present study, the impact of improving the hydrophilic microenvironment on the catalytic ability of Aspergillus niger fructosyltransferase, SucC, was investigated. By comprehensive and comparative bioinformatic analysis, it was predicted that a cysteine residue (C66) close to the catalytic triad (D64, D194 and E271) in SucC could play an important role in maintaining the spatial structure of the active site and facilitate the transport of substrates through the substrate tunnel. By simulating saturated mutagenesis, tertiary structure alignment, and molecular docking, it was predicted that a mutation from cysteine to serine (C66S) could increase the hydrophilic environment surrounding the active site without major changes in its structure. Two more amino acid residues (E296 and H310), in addition to D64, D122, R193, D194, and E271 in mutant C66S were predicted to be interacting with sucrose with the binding energy changing from -3.65 to -4.14 kcal/mol. Subsequently, mutant C66S was constructed by site-directed mutagenesis and expressed in Pichia pastoris GS115. The purified C66S mutant showed improved enzymatic activity with a 61.3% increase in its specific activity. Its Km value was decreased by 13.5% while the kcat value increased by 21.6%. When the mutant enzyme was used for FOS production, transfructosylation activity increased in the initial stages. The increase of hydrophilicity surrounding the active site enhanced the transfructosylating activity of the enzyme. Therefore, modification of the hydrophilic microenvironment surrounding the active site could be an alternative way to artificially evolve an enzyme’s catalytic efficiency.
An Improved Sparrow Search Algorithm Based on Complementary Inertia Weight and LSTM Optimization for Timer Serial Forecasting
Authors: Ma Jiaqi
Published: October 2024

When dealing with optimization problems that require to achieve optimal result within fewer iterations, the basic Sparrow Search Algorithm (SSA) shows insufficient solution accuracy and poor stability. In view of the above shortcomings, an improved adaptive Sparrow Search Algorithm based on complementary inertia weight (CIW-SSA) is proposed. Firstly, considering the lack of population diversity, chaos mapping is used to generate all individuals. Secondly, in order to obtain high-precision optimization results within short-term iterations, this paper created and implemented a pair of complementary inertia weights to improve search efficiency. The cooperation of this pair of complementary inertia weights not only adjusts the inertia of each individual, but also adjusts the step size of movement, which greatly improves the speed and accuracy of convergence. Thirdly, to response to the alert value of basic SSA and improve the capacity of exploration, Gaussian mutation and Cauchy mutation are organically added together to process of position update of producer. Simulation experiments were carried out through 18 classical benchmark functions with different characteristic, and the result show that the improved algorithm has faster convergence speed, more stable convergence properties and higher convergence accuracy. In addition, to prove the superiority of CIW-SSA within a few iterations, CIW-SSA is employed to optimize the hyperparameter of Long Short-Term Memory (LSTM) model for wind speed forecasting, and the test results prove the effectiveness of the improvement strategies.

The field of radiology is experiencing a surge in demand due to advances in medical imaging, particularly in techniques suchas magnetic resonance imaging and computed tomography (CT). However, the interpretation of these scans relies heavilyon the availability of experts, which is challenging in resource-limited regions. Recent advances in artificial intelligence anddeep learning offer promising solutions by assisting radiologists in image interpretation and diagnosis. This study focuses onvalidating DeepCTE3D, a deep learning–based model for segmenting and quantifying intracranial volume (ICV) and lateralventricular volume (LVV) in CT scans. The model’s performance was evaluated using a real-world dataset comprising diversepatient demographics and various scanner models, including normal and pathological scans. The evaluation process involveddeveloping a streamlined pipeline to generate ground-truth results and comparing them to the model’s outputs. DeepCTE3Dachieved high similarity scores for both ICV and LVV. Secondary analyses revealed differences in LVV and ICV between patientsexes and scanner models, although these differences were probably not clinically significant. This study highlights the potentialof DeepCTE3D in enhancing clinical triage and advancing neuroimaging applications, especially in scenarios where MRI is notfeasible.

Background
The emerging field of endophytic fungi studies their capability to enhance host plant growth and resistance through interactions. F. cymosum, a renowned medicinal plant, harbors a diverse yet inadequately understood array of endophytic fungi. Moreover, this plant, already at risk of endangerment, confronts additional threats posed by elevated temperatures and prolonged drought conditions. Hence, we aimed to identify drought-resistant endophytic fungi present in F. cymosum as a potential solution to alleviate this issue.
Results
The diversity of endophytic fungi across different habitats and tissue sections of F. cymosum was assessed using high-throughput sequencing technology in this investigation. Through correlation analysis, isolation, identification, and in vitro assays, we identified three target strains (JQ_R2, JQ_R14, JQ_L5) demonstrating growth-promotion and drought-resistance activities. These capabilities were subsequently confirmed in soil and hydroponic experiments involving F. cymosum. Transcriptomic and metabolomic analyses indicate that JQ_R2 enhances drought resistance in F. cymosum by boosting basal folate metabolism. Follow-up experiments validated the role of folate in aiding F. cymosum's drought resistance and demonstrated that the JQ_R2 strain produces folate consistently under both normal and drought conditions. During drought conditions, the dihydrofolate reductase (DHFR) activity of the JQ_R2 strain was substantially increased, suggesting that the JQ_R2 strain enhances drought resistance in F. cymosum, potentially via modulation of the folate metabolism pathway.
Conclusions
In conclusion, our study illustrates that F. cymosum plants thriving in arid regions host a more diverse array of drought-resistant endophytic fungi, with the JQ_R2 strain augmenting drought resistance in F. cymosum by boosting basal folate metabolism. This finding sheds light on the operational mechanism of drought-resistant fungal strains, bearing considerable importance for forthcoming research on endophytic fungi and mitigating agricultural drought challenges.
