Root-to-shoot signaling positively mediates source-sink relation in late growth stages in diploid and tetraploid wheat.

Non-hydraulic root source signaling (nHRS) is a unique positive response to soil drying in the regulation of plant growth and development. However, it is unclear how the nHRS mediates the tradeoff between source and sink at the late growth stages and its adaptive mechanisms in primitive wheat. To address this issue, a root-splitting design was made by inserting solid partition in the middle of the pot culture to induce the occurrence of nHRS using four wheat cultivars (MO1 and MO4, diploid; DM22 and DM31, tetraploid) as materials. Three water treatments were designed as 1) both halves watered (CK), 2) holistic root system watered then droughted (FS), 3) one-half of the root system watered and half droughted (PS). FS and PS were designed to compare the role of the full root system and split root system to induce nHRS. Leaves samples were collected during booting and anthesis to compare the role of nHRS at both growth stages. The data indicated that under PS treatment, ABA concentration was significantly higher than FS and CK, demonstrating the induction of nHRS in split root design and nHRS decreased cytokinin (ZR) levels, particularly in the PS treatment. Soluble sugar and proline accumulation were higher in the anthesis stage as compared to the booting stage. POD activity was higher at anthesis, while CAT was higher at the booting stage. Increased ABA (nHRS) correlated with source-sink relationships and metabolic rate (i.e., leaf) connecting other stress signals. Biomass density showed superior resource acquisition and utilization capabilities in both FS and PS treatment as compared to CK in all plants. Our findings indicate that nHRS-induced alterations in phytohormones and their effect on source-sink relations were allied with the growth stages in primitive wheat.

Mentha: Nutritional and Health Attributes to Treat Various Ailments Including Cardiovascular Diseases.

A poor diet, resulting in malnutrition, is a critical challenge that leads to a variety of metabolic disorders, including obesity, diabetes, and cardiovascular diseases. Mentha species are famous as therapeutic herbs and have long served as herbal medicine. Recently, the demand for its products, such as herbal drugs, medicines, and natural herbal formulations, has increased significantly. However, the available literature lacks a thorough overview of Mentha phytochemicals' effects for reducing malnutritional risks against cardiovascular diseases. In this context, we aimed to review the recent advances of Mentha phytochemicals and future challenges for reducing malnutritional risks in cardiovascular patients. Current studies indicated that Mentha species phytochemicals possess unique antimicrobial, antidiabetic, cytotoxic, and antioxidant potential, which can be used as herbal medicine directly or indirectly (such as food ingredients) and are effective in controlling and curing cardiovascular diseases. The presence of aromatic and flavor compounds of Mentha species greatly enhance the nutritional values of the food. Further interdisciplinary investigations are pivotal to explore main volatile compounds, synergistic actions of phytochemicals, organoleptic effects, and stability of Mentha sp. phytochemicals.

Molecular Characterization of Bacterial Isolates from Soil Samples and Evaluation of their Antibacterial Potential against MDRS.

Some soil microbes, with their diverse inhabitance, biologically active metabolites, and endospore formation, gave them characteristic predominance and recognition among other microbial communities. The present study collected ten soil samples from green land, agricultural and marshy soil sites of Khyber Pakhtunkhwa, Pakistan. After culturing on described media, the bacterial isolates were identified through phenotypic, biochemical and phylogenetic analysis. Our phylogenetic analysis revealed three bacterial isolates, A6S7, A1S6, and A1S10, showing 99% nucleotides sequence similarity with Brevibacillus formosus, Bacillus Subtilis and Paenibacillus dendritiformis. The crude extract was prepared from bacterial isolates to assess the anti-bacterial potential against various targeted multidrug-resistant strains (MDRS), including Acinetobacter baumannii (ATCC 19606), Methicillin-resistant Staphylococcus aureus (MRSA) (BAA-1683), Klebsiella pneumoniae (ATCC 13883), Pseudomonas aeruginosa (BAA-2108), Staphylococcus aureus (ATCC 292013), Escherichia coli (ATCC25922) and Salmonella typhi (ATCC 14028). Our analysis revealed that all bacterial extracts possess activity against Gram-negative and Gram-positive bacteria at a concentration of 5 mg/mL, efficiently restricting the growth of E. coli compared with positive control ciprofloxacin. The study concluded that the identified species have the potential to produce antimicrobial compounds which can be used to control different microbial infections, especially MDRS. Moreover, the analysis of the bacterial extracts through GC-MS indicated the presence of different antimicrobial compounds such as propanoic acid, oxalic acid, phenol and hexadecanoic acid.

Biodiesel Production Using Wild Apricot (Prunus aitchisonii) Seed Oil via Heterogeneous Catalysts.

We confined the formation and characterization of heterogenous nano-catalysts and then used them to produce biodiesel from the novel non-edible seed oil of Prunus aitchisonii. P. aitchisonii seeds' oil content was extracted at about 52.4 ± 3% with 0.77% FFA. Three different heterogenous nano-catalysts-calcined (CPC), KPC, and KOH-activated P. aitchisonii cake Titanium Dioxide (TiO2)-were synthesized using calcination and precipitation methods. The mentioned catalysts were characterized through XRD, SEM, and EDX to inspect their crystallin dimension, shape, and arrangement. Titanium dioxide has morphological dimensions so that the average particle size ranges from 49-60 nm. The result shows that the crystal structure of TiO2 is tetragonal (Anatase). The surface morphology of CPC illustrated that the roughness of the surface was increased after calcination, many macropores and hollow cavities appeared, and the external structure became very porous. These changes in morphology may increase the catalytic efficiency of CPC than non-calcined Prunus aitchisonii oil cake. The fuel belonging to PAOB stood according to the series suggested by ASTM criteria. All the characterization reports that P. aitchisonii is a novel and efficient potential source of biodiesel as a green energy source.

Review-Insights into Off-Label therapeutic strategies against mild and severe COVID-19 infection.

Currently, prevention and control of the coronavirus disease pneumonia epidemic situation are grim globally. To cope with total sheer carriers and patients of COVID-19 requires intensive medical support and adjunctive therapies to overcome the disease. The epidemic can be controlled with the help of both, disease suppression via community health measures and adjunctive therapies for patients suffering from infection. Till date, we do not have any proper anti-COVID-19 therapy. In order to achieve the overall realization of this pandemic, there is a need to identify treatments depending upon their direct or indirect targets; like inhibition of polyprotein synthesis, transmembrane serine protease, inhibition of viral entry and endocytosis. This could be possible by turning the focus in the direction towards the development of numerous tentative drugs, particularly in the severe to badly ill. Though, majority of these off-label adjunctive medicines are being inspected in a lot of clinical trials at different stages, scientific organizations have endeavored to elucidate the situation where these adjunctive drugs might be practiced as off-label, open- label or compassionate. Our review compiles the adjunctive therapies adopted in COVID-19 infected patients according to clinical severity in conjugation with practicing recommendations from existing guidance rules issued by global professional bodies in healthcare.

Characterization and phytostimulatory activity of bacteria isolated from tomato (Lycopersicon esculentum Mill.) rhizosphere.

Replacing agrochemicals with plant growth promoting bacteria (PGPB) may offset some of the environmental impacts of food production. The objectives of this study were to (1) isolate and characterize bacterial strains from tomato rhizosphere, including root, shoot and leaf, (2) select and identify the most promising PGPB strains, (3) verify the phytostimulatory activity and mineral uptake potential of selected strains. Bacterial strains isolated from tomato rhizosphere, were screened for phosphorous (P) solubilization, production of indole acetic acid (IAA), amylase activity, antibiotic resistance, and quick test strip (QTS) for biochemical characterization. The tested strains, positive for all five of these assays were selected for molecular identification and subjected to greenhouse growth trails with tomato and mung bean. Two strains were selected and identified as Bacillus cereus (B. cereus) isolated from rhizosphere and Klebsiella variicola (K. variicola) isolated from root endosphere using 16s rRNA sequences. Both strains produced IAA, gibberellic acid (GA3) and kinetin, however B. cereus showed potential GA3 and IAA production as compared to K. variicola. In tomato, only one growth variable (shoot length) was increased over the control by one of the selected bacterial strains (B. cereus). In mung bean, inoculation with either strain B. cereus or K. variicola increased shoot length and dry weight. Moreover, our results showed that the use of PGPB significantly increased plant growth and Fe, Zn, Ca, Mg, Cu, Na and K contents of plants. It seems that evaluated strains had a higher ability in boosting plant growth and higher yield.

Microbial synthesized cadmium oxide nanoparticles induce oxidative stress and protein leakage in bacterial cells.

The bactericidal activity of metal oxide nanoparticles (NPs) offers extensive opportunities in bioengineering and biomedicines. Bioengineered transition metals used in various forms against lethal microbes. In this study, Cadmium Oxide nanoparticles (CdO-NPs) were prepared through the co-precipitation method using fungal strain Penicillium oxalicum and cadmium acetate solution. The structure and elemental composition of the prepared NPs were determined by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), UV-Vis absorption spectroscopy, scanning electron microscope (SEM) and energy dispersive spectroscopy (EDS). Antibacterial activity was assessed through well diffusion method against Staphylococcus aureus (S. aureus), Shigella dysenteriae (S. dysenteriae), and Pseudomonas aeruginosa (P. aeruginosa). In addition, reactive oxygen species (ROS), reducing sugars and protein leakage contribution was examined against selected strains. The XRD analysis proved that the synthesized CdO-NPs possess a crystalline structure with an average crystalline size of 40-80 nm. FTIR confirmed the presence of organic compounds on the particle surface, while UV showed stability of the particles. SEM and EDS confirmed that CdO-NPs were successfully prepared and spherical. The maximum zone of inhibition against S. dysenteriae and P. aeruginosa was found and showed a less optical density of 0.086 after 18 h. ROS, reducing sugar, and protein leakage assay showed a significant difference as compared to control. Based on the present study, it is recommended that microbial mediated synthesized nanoparticles can be used as biomedicines for the treatment of different types of bacterial infections.

Impact of Sarcopenia on Post-Liver Transplant Hospitalization: Insights From a South Asian Cohort.

BACKGROUND: Sarcopenia's impact on post-liver transplant outcomes remains a subject of debate, with limited data from South Asia on its association with post-liver transplant hospital stays. This study aims to investigate sarcopenia's influence on post-transplant hospitalization duration in South Asians. METHODS: In this retrospective study, patients with liver cirrhosis who underwent living-donor liver transplantation (LDLT) at Shifa International Hospital in Islamabad, Pakistan, between January 2022 and January 2023 were included. Computed tomography (CT) images were used to assess the skeletal muscle index (SMI). The areas of the psoas, erector spinae, multifidus, quadratus lumborum, rectus abdominis, transverse abdominis, and internal/external oblique muscles were quantified at the level of L3. The data were analyzed using SPSS version 29.0 (IBM). RESULTS: There was a total of 84 patients. Mean age was 47.4 ± 12.0 years. There were 62 (73.8%) male patients and 22 (26.2%) female patients. Hepatitis C was noted in 36 (42.9%) patients. Twenty-two (26.2%) patients had hepatocellular carcinoma. Sarcopenia was identified in 58 (69.0%) patients. No significant association was observed between sarcopenia and intensive care unit (ICU) or general floor stays. Regression analysis identified pre-transplant model for end-stage liver disease-sodium (MELD-Na) score as the sole significant factor associated with both ICU and total length of stay (P value .002; P value .009). CONCLUSION: In our population, sarcopenia did not correlate with post-transplant ICU or overall hospital stay. The pre-transplant MELD-Na score emerged as the most influential predictor of length of stay. Therefore, delaying liver transplant procedures based on muscle mass estimations may not be a practical clinical approach for South Asian patients.

The data regarding traditional ethnomedicines (TEMs) and phytogeography with conservation analysis of wild plants were collected via structured and semi structured interviews of 150 participants belonging to various professions and of both genders. Prior consent and permission were obtained from family heads and from all the participants, and the data were shared with all the informants through the local female translator guide. To validate the collected data, various microstatistical tools, such as the informant consensus factor (ICF), fidelity level (FL) and data matrix ranking (DMR) were used. The relative frequency of citations (RFC) and rank order of popularity (ROP) were also calculated to determine and authenticate the relative importance of TEMs which may be further studied in future research and used for drug discovery. In the present study, 150 locally important plants belonging to 69 families were documented, and the Rosaceae was the most dominant and prevalent family. The results indicated that many locally important plants have multiple uses such as food, medicine, fodder, shelter, ornamental and fuel. The TEMs obtained from these plants have been known to be useful for curing various infirmities such as flu, renal disorders, fever, malaria, cough, migraine, whooping cough, influenza, skin rashes, allergies, stomach aches, wounds and bruises, diabetes, tumours and joint pains. The ICF analysis revealed that renal calculus, malaria, fever, whooping cough, rheumatoid arthritis and arthritis were prevalent infirmities of the mountainous area. The FL analysis indicated the popularity of these plants used in various TEMs and among these Artemisia maritima and Berberis lycium were the most common. The DMR indicated that Pinus roxburghii was the most common species being used for multipurpose by the indigenous communities. The highest use value index was found for Indigofera linifolia. The relative frequency of citations was calculated to determine the importance of plants in traditional ethnomedicine, highlighting Morus nigra, Pinus wallichiana, and Rosa indica as significant species. The Jaccard index indicated a high level of novelty in the research which can be exploited for neo-drug discovery and drug development. In conclusion, this study has successfully documented the ethnobotanically and ethnomedicinally important plants in District Sudhnoti, Azad Jammu and Kashmir, Pakistan. The findings of this research contribute to the preservation and documentation of cultural heritage, as well as provide a foundation for further studies in ethnobotany, ethnopharmacology and biodiversity conservation efforts for sustainable provision of wild flora to the indigenous communities which will also assist in combating drasting climatic changes.

Supplemental Sodium Nitroprusside and Spermidine Regulate Water Balance and Chlorophyll Pigments to Improve Sunflower Yield under Terminal Drought.

Drought is an inevitable environmental stress that drastically hampers the growth, productivity, and quality of food crops. Exogenous sodium nitroprusside and spermidine have decisive functions in the growth enhancement of plants; nevertheless, their specific role in mediating stress responses to improve drought tolerance in sunflowers at the reproductive stage (terminal drought) remains largely unknown. In the present study, we explored the positive effects of sodium nitroprusside and spermidine on physiological responses to increase in sunflower yield during periods of terminal drought. Initially, various doses (50, 100, 150, 200, 400 µM) for each sodium nitroprusside or spermidine were foliar sprayed to improve water content, chlorophylls, and biomass accumulation in sunflower seedlings under control (100% FC) and drought (60% FC) conditions. Optimized rates (100 µM for sodium nitroprusside) and (100 µM for spermidine) were further tested alone and in combination to assess drought tolerance potential and their ultimate impact on yield under drought stress. Drought exposure caused a marked reduction in relative water content (26%) and chlorophyll a (31%) and b (35%) contents; however, sodium nitroprusside and spermidine at 100 µM significantly improved the growth of sunflower (13%). Furthermore, combined use of sodium nitroprusside and spermidine at 100 + 100 µM markedly improved the achenes per head (16%), 1000-achene weight (14%), and ultimately grain (28%) and oil (21%) yields of sunflowers under drought stress. A strong association was found between the 1000-achene weight and the achene yield of sunflower. Hence, combined sodium nitroprusside and spermidine upregulate water balance and chlorophyll contents to increase sunflower yield under terminal drought.

Above-and below-ground feedback loop of maize is jointly enhanced by plant growth-promoting rhizobacteria and arbuscular mycorrhizal fungi in drier soil.

Drought is a potent abiotic stressor that arrests crop growth, significantly affecting crop health and yields. The arbuscular mycorrhizal fungi (AMF), and plant growth-promoting rhizobacteria (PGPR) can offer to protect plants from stressful environments through improving water, and nutrient use efficiency by strengthening plant root structure and harnessing favorable rhizosphere environments. When Acaulospora laevis (AMF) and Bacillus subtilus (PGPR) are introduced in combination, enhanced root growth and beneficial microbial colonization can mitigate drought stress. To assess this potential, a pot experiment was done with maize (Zea mays L.) to explore the effects of A. laevis and B. subtilus under different water levels (well-watered = 80 %; moderate water stress = 55 %; and severe water stress = 35 %) on maize yield, soil microbial activities, nutrients contents, root, and leaf functioning. Plants exposed to severe drought stress hampered their root and leaf functioning, and reduced grain yield compared with control plants. Combined use of AMF and PGPR increased root colonization (104.6 %-113.2 %) and microbial biomass carbon (36.38 %-40.23 %) under moderate to severe drought conditions over control. Higher root colonization was strongly linked with elevated ACC (aminocyclopropane-1-carboxylic acid) production, subsequently enhancing water use efficiency (21.62 %-12.77 %), root hydraulic conductivity (1.9 %-1.4 %) and root nutrient uptake under moderate to severe drought conditions. Enhanced nutrient uptake further promoted leaf photosynthetic rate by 27.3 %-29.8 % under moderate and severe drought stress. Improving leaf and root physiological functioning enhanced maize grain yield under stressful environments. Furthermore, co-inoculation with AMF-PGPR reduced cellular damage by lowering oxidative enzyme levels and increasing antioxidative enzyme activities, improving plant performance and grain yield under stressful environments. Conclusively, the synergistic interaction of AMF with PGPR ensured plant stress tolerance by reducing cellular injury, facilitating root-leaf functioning, enhancing nutrient-water-use-efficiencies, and increasing yield under drought stress.

Investigation on the insecticidal activities of cyanobacterial extracts as an alternative source for the management of fall armyworm, Spodoptera frugiperda (J. E. Smith) (Lepidoptera: Noctuidae).

The Spodoptera frugiperda is a notorious pest with a broad host range. It severely damages crops, mainly in areas of the globewhere maize and sorghum are grown. The pest is difficult to control due to its adaptive nature and resistance to several insecticides available in the market. So, an identification of the alternative strategy is the prime important in the present context. Insecticidal activities of cyanobacterial extracts were evaluated in the laboratory as a biocomponent against S. frugiperda. The crude extracts of Nostoc muscorum and Spirulina sp. were prepared by using ethanol, methanol and petroleum ether solvents. Soxhlet apparatus was used for extraction. S. frugiperda larvae in their second instar were given access to fragments of maize leaf that had been treated with various cyanobacterial extracts. The findings displayed that the petroleum ether extract of N. muscorum had the lowest LC50 value of 155.22 ppm, followed by petroleum ether extracts of Spirulina, ethanol extract of N. Muscorum, methanol extract of N. muscorum, ethanol and methanol extract of Spirulina with an LC50 values of 456.02, 710, 780, 1050 and 1070 ppm respectively. Later, the effect of LC50 values on many biological parameters like the larval duration and pupal stages, the percentage of pupation, the weight of the pupal stage, the malformation of the pupal and adult stages, adult emergence percentage, fertility and the longevity of the male and female adult stages of S. frugiperda was examined. The gas chromatography-mass spectrometry (GC-MS) was used to analyse the crude extract to identify the bioactive components that were responsible for the insecticidal properties. The major compounds detected were diethyl phthalate (19.87 %), tetradecane (5.03%), hexadecanoic acid, ethyl ester (4.10 %), dodecane (4.03%), octadecane (3.72%), octadecanoic acid, methyl ester (3.40 %), ethyl oleate (3.11 %), methyl ester. octadecenoic acid (3.04 %), heptadecane (3.04 %) and phytol (3.02 %). The presence of several bioactive chemicals in the cyanobacterial extracts may be the reason for their insecticidal actions, thus it can be used as an alternative and new source to combat fall armyworm and other crop pests.

Foliar epidermal anatomical characteristics of Apiaceae species endemic to Ulleungdo and Dokdo Islands, Republic of Korea.

The foliar epidermal anatomical characteristics of the two endemic Apiaceae species of Korea Bupleurum latissimum Nakai and Dystaenia takesimana (Nakai) Kitag. were investigated. The taxonomically important characteristics of these two species were identified and described to help understand their classical taxonomy. Scanning electron microscopy (SEM) was used to observe the anatomical characteristics of the studied species in detail. The comparative foliar epidermal anatomical characteristics were observed in the present research for the two-endemic species. Some of the most important foliar epidermal anatomical characteristics were observed to distinguish them, including the epidermal cell shape and size, stomata type, and trichomes shape and size. SEM provided sufficient evidence to distinguish the study species. The foliar epidermal anatomical characteristics provide sufficient information to differentiate these two species from their closely related taxa. RESEARCH HIGHLIGHTS: Apiaceae species endemic to Ulleungdo and Dokdo Islands exhibit unique foliar epidermal anatomical characteristics that can be used for taxonomic identification and classification. This study contributes to the documentation of the plant diversity of Ulleungdo and Dokdo Islands, and highlights the need for further research on the biogeography and conservation of these endemic plant species.

Evaluation of potential inhibitory effects on acetylcholinesterase, pancreatic lipase, and cancer cell lines using raw leaves extracts of three fabaceae species.

The present study examined the biological potential and phytochemicals of Sophora mollis, Mucuna pruriens, and Indigofera atropurpurea methanolic leaf extracts. In vitro anti-acetylcholinesterase and anti-lipase assays were performed using different concentrations of plant extracts, and the IC50 values were determined. The cytotoxic potential of the selected plant extracts was assessed against HeLa, PC3, and 3T3 cell lines using an MTT assay. S. mollis leaf extract displayed the highest inhibition percentage (114.60% ± 19.95 at 1000 µg/mL) for the anti-acetylcholinesterase activity with a prominent IC50 value of 75.9 µg/mL. The anti-lipase potential was highest with the M. pruriens leaf extract (355.5 µg/mL IC50), followed by the S. mollis extract (862.7 µg/mL IC50). Among the cell lines tested, the cytotoxic potential of the I. atropurpurea extract (91.1 ppm IC50) against the PC3 cell line was promising. High-performance liquid chromatography revealed gallic acid, chlorogenic acid, caffeic acid, vanillic acid, rutin trihydrate, and quercetin dihydrate in varying concentrations in all plant species. The concentration of chlorogenic acid (69.09 ppm) was highest in M. pruriens, and the caffeic acid concentration (45.20 ppm) was higher in S. mollis. This paper reports the presence of bioactive therapeutic compounds in selected species of the Fabaceae family that could be micro-propagated, isolated, and utilized in pharmaceutical industries.

The Key Roles of ROS and RNS as a Signaling Molecule in Plant-Microbe Interactions.

Reactive oxygen species (ROS) and reactive nitrogen species (RNS) play a pivotal role in the dynamic cell signaling systems in plants, even under biotic and abiotic stress conditions. Over the past two decades, various studies have endorsed the notion that these molecules can act as intracellular and intercellular signaling molecules at a very low concentration to control plant growth and development, symbiotic association, and defense mechanisms in response to biotic and abiotic stress conditions. However, the upsurge of ROS and RNS under stressful conditions can lead to cell damage, retarded growth, and delayed development of plants. As signaling molecules, ROS and RNS have gained great attention from plant scientists and have been studied under different developmental stages of plants. However, the role of RNS and RNS signaling in plant-microbe interactions is still unknown. Different organelles of plant cells contain the enzymes necessary for the formation of ROS and RNS as well as their scavengers, and the spatial and temporal positions of these enzymes determine the signaling pathways. In the present review, we aimed to report the production of ROS and RNS, their role as signaling molecules during plant-microbe interactions, and the antioxidant system as a balancing system in the synthesis and elimination of these species.

Biological Characterization of Polystichum lonchitis L. for Phytochemical and Pharmacological Activities in Swiss Albino Mice Model.

Polystichum lonchitis L. is a fern belonging to the family Dryopteridaceae. The present study was conducted to evaluate its pharmacological, antioxidant, and phytochemical properties, and to conduct GC-MS screening of P. lonchitis. The acetic acid-induced writhing test, yeast-induced hyperpyrexia method, carrageenan-induced rat paw edema model, and charcoal meal test model were carried out to assess analgesic, antipyretic, anti-inflammatory, and antispasmodic activity, respectively. DPPH was used as an antioxidant, while the phytochemical screening was conducted using standard scientific methods. Among the pharmacological activities, the most significant effects were observed in the analgesic and anti-inflammatory activities, followed by the antipyretic and antispasmodic activities, at a dose of 450 mg/kg after the 4th hour, compared with 150 mg/kg and 300 mg/kg. For the evaluation of antioxidant activities, the most significant results were detected in the methanolic and aqueous extracts. The detection of flavonoids and phenol occurred most significantly in the methanolic extract, and then in the ethanolic and aqueous extracts. The main compounds detected using GC-MS analysis with a high metabolic rate was 𝛼-D-Galactopyranoside, which had a metabolic rate of 0.851, and methyl and n-hexadecanoic, which had a metabolic rate of 0.972. Overall, the results suggested that P. lonchitis had a strong potential for pharmacological activities. The suggested assessment provided a way to isolate the bioactive constituents and will help to provide new medicines with fewer side effects. Due to the fern's effectiveness against various diseases, the results provide clear evidence that they also have the potential to cure various diseases.

Unveiling Lathyrus aphaca L. as a Newly Identified Host for Begomovirus Infection: A Comprehensive Study.

The Begomovirus genus of the family Geminiviridae comprises the largest group of geminiviruses. Begomoviruses are transmitted by the whitefly complex (Bemisia tabaci) and infect dicotyledonous plants in tropical and subtropical regions. The list of begomoviruses is continuously increasing as a result of improvements in the methods for identification, especially from weed plants, which are considered a source of new viruses and reservoirs of economically important viruses but are often neglected during diversity studies. Lathyrus aphaca L. weed plants (yellow-flowered pea) with varicose veins and discoloration of the leaves were found. Amplified genomic DNA through rolling circular amplification was subjected to PCR analysis for the detection of the viral genome and associated DNA-satellites (alphasatellites and betasatellites). A full-length sequence (2.8 kb) of a monopartite begomovirus clone was determined; however, we could not find any associated DNA satellites. The amplified full-length clone of Rose leaf curl virus (RoLCuV) reserved all the characteristics and features of an Old World (OW) monopartite begomovirus. Furthermore, it is the first time it has been reported from a new weed host, yellow-flowered pea. Rolling circle amplification and polymerase chain reaction analysis of associated DNA satellites, alphasatellite, and betasatellite, were frequently accomplished but unable to amplify from the begomovirus-infected samples, indicating the presence of only monopartite Old World begomovirus. It is observed that RoLCuV has the capability to infect different hosts individually without the assistance of any DNA satellite component. Recombination in viruses is also a source of begomovirus infection in different hosts.

Thickness effects of polyethylene and biodegradable film residuals on soil properties and dryland maize productivity.

Plastic film residuals are increasingly remaining in cultivated lands. However, it is a critical issue how residual plastic type and thickness affect soil properties and crop yield. To address this issue, in situ landfill was conducted using thick polyethylene (PEt1), thin polyethylene (PEt2), thick biodegradable (BIOt1), thin biodegradable (BIOt2) residues, and CK (control) with no residues landfill in a semiarid maize field. The findings demonstrated that the impact of various treatments on soil characteristics and maize yield varied considerably. Soil water content decreased by 24.82% in PEt1 and 25.43% in PEt2, compared to BIOt1 and BIOt2, respectively. BIOt2 treatment increased soil bulk density by 1.31 g cm-3 and lowered soil porosity by 51.11%, respectively; it also elevated the silt/clay proportion by 49.42% relative to CK. In contrast, microaggregate composition in PEt2 was higher (43.02%). Moreover, BIOt2 lowered soil nitrate (NO3-) and ammonium (NH4+) content. Compared with other treatments, BIOt2 resulted in significantly higher soil total nitrogen (STN) and lower SOC/STN. Finally, BIOt2 exhibited the lowest water use efficiency (WUE) (20.57 kg ha-1 mm-1) and yield (6896 kg ha-1) among all the treatments. Therefore, BIO film residues exhibited detrimental impacts on soil quality and maize productivity compared to PE film ones. Considering film thickness, thin residual films more evidently influenced soil quality and maize productivity than thick film ones.

Radon concentration and potential risks assessment through hot springs water consumption in the Gilgit and Chitral, Northern Pakistan.

This study investigated the concentration of radon (222Rn) in hot springs water. For this purpose, 222Rn concentration was measured using the RAD7 (Durridge Company, USA) in the water of hot springs located in Tata Pani, Gilgit (n = 4), and Garam Chashma, Chitral (n = 6), northern Pakistan. Water samples from the springs (background, n = 3) were also collected and analyzed for 222Rn concentration 40-50 km away from the hot springs in Gilgit and Chitral, northern Pakistan, to be used as background/reference concentration. The determined 222Rn in hot springs water surpassed the threshold of maximum contamination level (MCL, 11.1 Bq/L) set by the United States Environmental Protection Agency (US-EPA) in 100% samples collected from Tata Pani, Gilgit, and Garam Chashma, Chitral sites. Soil 222Rn along with the hot springs exhibited a decreasing trend with increasing distance. 222Rn concentration in hot springs water was used to calculate the exposure doses of human health through ingestion and inhalation pathways. The total effective dose for human (EWT) of 222Rn contaminated water consumption was 626 µSv/a in the Tata Pani, Gilgit and 34.7 µSv/a in the Garam Chashma, Chitral. Results revealed that hot springs water in the Tata Pani, Gilgit had surpassed the threshold limit (100 µSv/a) set by the World Health Organization (WHO). This study concluded that hot springs water should be avoided for drinking and other domestic uses.
