Abstract

Tomato chlorosis virus (ToCV), causing yellowing disease in tomato, is a phloem-limited, whitefly-transmitted crinivirus that mainly affects plants by reducing chlorophyll content. During a survey conducted in 2019, cirinivirus-specific yellowing symptoms were observed in the tomato fields in Multan, Khanewal, and Lodhran districts of Pakistan. To confirm the etiology of the yellowing disease of tomato, a total of 76 symptomatic and 22 asymptomatic samples were collected out of which 72% of the tested plants were found to be positive for ToCV using RT-PCR. The full genomic nucleotide sequences of two selected ToCV-isolates were obtained by next-generation sequencing (NGS). RNA1 and RNA2 of each isolate comprised 8594 and 8242 nucleotides, respectively. The NGS results were verified by sequencing the amplified overlapping fragments of RNA1 and RNA2 using specific primers designed in this study. In BLASTn analysis for ToCV-Pak1 and ToCV-Pak2, RNA1 from both isolates had the highest similarities (99.41-99.46%) with a South Korean isolate; RNA2 had the highest similarities of 99.67-99.64% with a Greek isolate for Pak1 and Turkish isolate for Pak2, respectively. Phylogenetic analysis indicated that RNA1 of the Pakistani isolates clustered together, forming a subclade, and RNA2 from one of the Pakistani isolates (MN869006) clustered with a Brazilian isolate. At the same time, the other one (MN869007) fell close to a Turkish isolate. Statistical analysis indicated a low polymorphic frequency in RNA1 but a higher polymorphic frequency in RNA 2 quantifying the degree of variation in the analyzed isolates which may result in emergence of new strains with altered levels of virulence. One probable recombination event was detected in RNA1. Analysis revealed that RNA1 of Pak1 and Pak2 is recombinant between South Korean isolate (major parent) and Spanish isolates (minor parent) with recombinant breakpoints at 6172 and 6668 nucleotide positions from the 5′ end, respectively. This study provides the first full genomic analysis and the genetic diversity of ToCV-RNA1 infecting the tomato plant in Pakistan. Understanding the trends and rate of variation in the isolates may provide an insight into the development of resistance in tomato plants against tomato yellowing disease.

Abstract

Mutations in BCKDHA, BCKDHB, DLD and DBT are associated with Maple Syrup Urine Disease (MSUD) in different populations worldwide, therefore screening of these genes is crucial for genetic counseling, diagnosis and treatments of MSUD in patients suffering from MSUD. The present study was therefore carried out by screening MSUD patients from different regions including Baku, Sheki-Zagatala, Guba-Khachmaz, Lankaran-Astara zones to establish the genetic spectrum of MSUD patients of in Azerbaijan population. The cohort consisted of 800 patients clinically diagnosed with MSUD from the year 2015 to 2020. The gene panel sequencing (BCKDHA, BCKDHB, DLD and DBT) was performed by amplification of exonic sequences using the polymerase chain reaction (PCR) method followed by Sanger sequencing of the amplified product. For the confirmation of identified mutation a control panel of 140 healthy individuals was also collected from the population. The sequencing of the exonic sequence of the four genes resulted in identification of four missense variants. One patient carried compound heterozygous variants 1221(A>G) and 972 (C>T) in exon 9 and 10 respectively while another patient had homozygous 508(C>T) variant in BCKDHB, and homozygous 1199(A>G) was found in DBT in another patient. All the three patients carrying the identified mutations were from Guba-Khachmaz zone: one was Azerbaijani Turk, and two were Lezgi ethnic group. The in silico analysis predicted the variants to be pathogenic for protein function. In conclusion, the present study highlights the genetic role of BCKDHB and DBT in onset of MSUD in Azerbaijan especially Guba-Khachmaz zone where BCKDHB variants found to be more common in MSUD patient with followed by DBT. The identified variants were absent from the control group, thus suggesting their role in disease manifestation. Out of the 800 MSUD screened patients excluded cases might be having deep intronic mutation either in BCKDHB and DBT or other gene or might be having novel gene which could only be identified through exome/genome sequencing of the remaining patient.

Abstract

This study used 38 morphological characteristics, IRAP and SCoT markers, and DNA barcoding to assess the relationships among seven date palm cultivars commonly grown in North Sinai, Egypt—five classified and two unknowns. Results of morphological characterization analysis within date palm cultivars showed significant variability (P ≤ 0.05) in tree, leaf, fruit, and seed morphological traits. Principal component analysis revealed strong relationships among certain morphological traits and cultivars, forming four major homogeneous variable groups. Cluster analyses revealed that Beid El Gamal exhibited the lowest genetic similarity among the seven cultivars, while the highest similarity index was observed between Amri and Yellow Majhal, Hayani and Red Majhal, and Khedri and Kapoushi. The evaluation was performed using IRAP and SCoT markers; IRAP markers generated 97 amplicons with 36% polymorphism, while SCoT markers produced 89 amplicons with 45% polymorphism. Genetic similarity coefficients ranged from 0.83 to 0.93, with the highest similarity (0.93) observed between Amri and Yellow Majhal cultivars. DNA barcoding using rbcL, matK, and trnH genes successfully differentiated the cultivars into distinct phylogenetic groups. Molecular analyses revealed that Amri and Yellow Majhal cultivars were most closely related, while Beid El Gamal showed the lowest similarity. We concluded that analyzing morphological traits can distinguish date palm cultivars, but it is time-consuming and requires specific traits to identify each cultivar. By integrating morphological and genetic characteristics, we achieved more reliable identification. Molecular markers, such as IRAP and SCoT—particularly using IRAP-2204 or SCoT-09 primers—along with DNA barcoding, allow for quick and accurate differentiation of closely related cultivars, even unknown ones. This approach enhances sustainable date palm production by conserving genetic resources, improving breeding programs, verifying identities, tracking genetic diversity, and protecting local cultivars.

Abstract

Upland rice cultivation in highland regions is often challenged by drought, leading to poor seedling growth and low productivity. This study aimed to investigate the physiological, biochemical, and anatomical responses of the Thai rice landrace Nhonkhab under drought and rewatering conditions. After germination, 28-day-old Nhonkhab rice seedlings were deprived of water for 7 days (35 days old) and then rewatered for 5 days (40 days old). Growth, physiological, biochemical and anatomical characteristics of the 35 and 40-day-old seedlings were evaluated. Results showed that drought stress significantly reduced relative water content (RWC) (-36.38%) but was rapidly restored after rewatering (+12.15%) when compared to the control. After drought stress treatment, malondialdehyde (MDA) content and electrolyte leakage (EL) percentage increased (+150% and +59.37%, respectively), indicating oxidative stress and membrane damage. Growth and developmental adaptations, such as elongated roots and curled leaves, facilitated survival during drought, with leaves unfurling post-rewatering. Following rewatering, rice plants exhibited robust recovery, supported by internal structural adaptations such as increasing stomatal density, thickening of the cuticle layer around the midrib and leaf blades, increasing bulliform cells number and size, and modifications in vascular bundles. Principal component analysis (PCA) and hierarchical cluster analysis (HCA) revealed distinct patterns in growth, physiological, and anatomical traits across control and treatment groups. These findings provide valuable insights for rice production planning in drought-prone highlands and for selecting or breeding drought-resistant cultivars with improved resilience and productivity.

Abstract

Irrigation with saline water significantly reduces maize cultivation and productivity worldwide. Therefore, it is essential to investigate sustainable approaches to mitigate diverse effects of irrigation with saline water on various physiological and agronomical characteristics of maize, such as foliar application of selenium and proline. Two experiments, consequently, were carried out in the experimental farm of the College of Sciences and Humanities, Shaqra University, Al-Quwayiyah Governorate, Kingdom of Saudi Arabia during the two successive autumn seasons of 2022 and 2023. Three saltwater irrigation treatments were separately applied using a randomized complete block design with a split-plot arrangement with three replications. In each one of these, three rates of selenium were distributed in the main plots, whereas three rates of proline were applied in the sub-plots. Selenium and proline applications, individually or combined, significantly reduced the effects of saltwater irrigation stress on physiological and agronomic traits of maize. Obviously, optimal results were achieved with selenium at 10 mg L^-1 and proline at 10 mM, effectively mitigating the adverse effects of saltwater irrigation on the physiological and agronomic traits of maize. At a moderate salinity level of 2000 mg L^-1 NaCl, the application of 5, and 10 mM proline improved grain yield per plant by 7.76 and 5.54 %, as well as 17.62 & 7.99%; grain yield per hectare by 7.18 and 7.72 %, along with 19.11 & 8.33 %; and stover yield per hectare by 8.56 and 6.87 %, as well as 16.38 and 9.05 %, in both seasons, respectively under the application of 5, and 10 mg L^-1 selenium, respectively, as compared to severe salinity level of 3000 mg L^-1 NaCl. This in turn showed that exogenous selenium and proline application, individually or combined, were effective strategies in mitigating the harmful effects of salinity on physiological and agronomic traits of maize.

Abstract

In the present study, Clostridium perfringens (C. perfringens) was isolated from clinically suspected cases of necrotic enteritis. For this purpose, the intestinal samples collected, after enrichment in thioglycolate broth were inoculated on perfringens-specific media (tryptose sulphite cycloserine agar) in an anaerobic jar having a gas pack. After incubation of 24hrs at 37°C, characteristic black colonies on TSC agar were used for confirmation by gram staining. Molecular confirmation was carried out with species-specific 16 s rRNA primer and DNA was amplified further for different toxin genes i.e. cpa, cpb, etx, iap, cpe, and net B for toxinotyping of C. perfringens. These isolates were further used to induce necrotic enteritis in poultry birds and for this purpose experimental trials were carried out to compare the ameliorative effects of antimicrobial alternatives i.e. Tibetan tea extract, black tea extract. and they were compared with commercial available AGPs. Data was analyzed through analysis of variance (ANOVA) through SAS University Edition. Results of the experimental trial demonstrated that there is a significant improvement in physiological performance and immunity of the birds supplemented with tea extracts and exposed to the NE challenge. The current study finding conclude that the both Tibetan and Black tea extracts can be used separately or in combination for the control of necrotic enteritis in poultry. Tea phenolics have proved their potential as an alternative to antimicrobials and to address antimicrobial resistance in poultry.

Abstract

Brucellosis is a highly contagious zoonotic disease caused by the bacterium Brucella spp. that distresses mutually animals and humans, especially in underdeveloped countries with poor control programs. In adult cattle, the disease affects mainly the reproductive organs, thus causing major losses in production and reproduction, such as abortion and reduced fertility. This study involves the collection of 460 blood samples from dairy farms, which were analysed for brucellosis infection using the Rose Bengal Test (RBT). Additionally, data on the animals’ history, including placenta (retained), repeat breeding, their age, abortion, and lastly calving, were also recorded. To address the problem of class imbalance between the positive and negative classes, a technique, known as Synthetic Minority Over-sampling Technique (SMOTE) was applied in the research work. A total of five algorithms were used in this paper among them multilayer perceptron (MLP) and weekadeeplearning4j showed the best results for the prediction of brucellosis having 93.59% and 93.94% accuracy, respectively. Besides, risk factors are ranked based on their importance as ordered as retained placenta > repeat breeding > calving > abortion > age, and three association rules are made to understand the correlation of the factors for occurring the disease. By applying this study, early diagnosis of the disease could be possible to mitigate the economic losses.

Abstract

Lipid-polymer hybrid nanoparticles (LPHNPs) are innovative composite structures featuring a core-shell design, with a polymeric nanoparticle core surrounded by PEGylated lipid layers. This architecture combines liposome circulation with nanoparticle strength, offering a promising solution for multidrug-resistant cancers. The current study aimed to develop an integrated platform that leverages these advantageous characteristics. To achieve this, Tamoxifen-loaded nanoparticles were formulated using emulsion solvent evaporation technique with PLGA poly (lactic-co-glycolic) acid polymer, while Doxycycline-containing liposomes were developed through a film hydration method. These two components were then combined to fabricate LPHNPs. A range of physicochemical and structural analyses, including dynamic light scattering (DLS), laser diffraction analysis (LDA), and scanning electron microscopy (SEM), were performed. Cellular cytotoxicity was quantitatively assessed using the MTT assay, and biocompatibility was evaluated through in vivo acute toxicity tests on female albino mice. The average hydrodynamic sizes of Tamoxifen and Doxycycline formulations were 198.80 ± 2.10 nm and 100.5 ± 1.29 nm, respectively. After coating Tamoxifen nanoparticles with Doxycycline liposomes, resultant LPHNPs exhibited a diameter of 200.4 ± 2.51 nm and a zeta potential of 4.45 ± 2.51 mV. Notably, LPHNPs demonstrated a significant increase in cytotoxicity (p < 0.001) and showed reduced in vivo toxicity compared to free drugs, with no discernible toxicity observed in histopathology of vital organs, confirming their safety and efficacy.

Abstract

Tacca (Tacca leontopetaloides (L.) Kuntze) is a tuberous plant commonly growing in coastal areas, both in open and shaded areas. This study aimed to identify the agronomical characteristics and metabolite content of Tacca growing under various levels of natural shading. The research was conducted in the southern coastal area of Garut Regency (West of Java-Indonesia) by observing the plant growth and production, and metabolite content of Tacca tubers under conditions of natural full sunlight (0% shade/FL), moderate shade (40% shade/MS), and heavy shade (75% shades/HS) in three different locations as replications. Three mature plants (±7 months old) in each shade level and replication were randomly selected as observed samples. The result presented that Tacca’s growth increased with the increasing shading levels. Nonetheless, tuber production showed the highest value under MS, which increased by 76.64% and 35.20% compared to FL and HS, respectively. Fourteen metabolites were detected in Tacca tuber grown in MS and FL, while only eight metabolites were detected in HS. The highest concentration of the metabolites obtained in MS were 8 metabolites (57%) and followed by FL and HS with 3 (21%) and 1 metabolite (7%), respectively. Moderately shaded areas have great potential to be used as cultivation land to produce high-quality Tacca tubers.

Abstract

Vibrating sample magnetometry (VSM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) were used to characterize iron oxide nanoparticles (IONPs) synthesized via co-precipitation. TEM showed that the synthesized NPs had an average size of 13.8 nm and exhibited a saturation magnetization of 50.26 emu/gm, while XRD confirmed their crystallinity. This study assessed the toxicological impacts of IONPs on hematology, serum biochemistry, genotoxicity, and the histoarchitecture ailments in different visceral organs (liver, kidneys, spleen, brain, and heart of rabbits (Oryctolagus cuniculus). A total of 16 healthy adult rabbits without infections were randomly assigned to two groups (A and B). Group A was the control whereas group B received 0.5 mg/kg bw of IONP dose once for 10 days via marginal ear vein. Visceral tissues and blood were obtained from each rabbit on days 5 and 10 of trial. The results showed a significant reduction in antioxidant enzymes and an increase in oxidative stress. The hematological profile indicated lower values of red blood cell counts, hematocrit, lymphocyte, and monocyte while significantly higher values of total white blood cell counts and neutrophil (%) in IONPs-treated rabbits. Serum biomarkers of the liver, kidneys, and heart exhibited escalated concentrations in IONPs-treated rabbits. Histopathological examination revealed notable tissue alterations like necrosis of hepatocyte, congestion, and bile duct hyperplasia in the liver, neuronal degeneration, necrosis, and microgliosis in the brain, tubular degeneration, necrosis, and congestion in the kidneys and disorganization of cardiac myofibers and edema in cardiac tissue. A significantly increased DNA damage was assessed in multiple visceral organs of treated rabbits. In conclusion, our findings demonstrate that exposure to IONPs induces toxic effects in multiple visceral organs including the kidneys, liver, spleen, heart, and brain in rabbits.
