The thermosensitive genic male sterility (TGMS) system is widely used for hybrid rice cultivation. Male sterile lines are sensitive to temperature and this trait is controlled by the TMS5 gene, encoding a nuclear ribonuclease Z (RNase ZS1) enzyme, which is involved in the degradation of ubiquitin fusion ribosomal protein L40 (UbL40) mRNAs. Mutation in the TMS5 gene will lead to loss of function of RNase ZS1, resulting in accumulation of high levels of UbL40 mRNAs, thereby causing male sterility. We developed tms5 mutants through targeted mutagenesis of the TMS5 gene via CRISPR/Cas9 technology in three rice genetic backgrounds, viz., CO51, ADT39, and ASD16. The tms5 mutants exhibited pollen sterility percentages ranging from 2.05 to 91.1
Stability analysis plays a crucial role in plant breeding programs aimed at enhancing crop productivity and resilience. Chili yield stability studies based on the interaction of genotype x environment have been widely conducted, as stable yield is very substantial in the formation of sustainably high-yielding chili varieties. Multi-environmental trials, conducted across different seasons, locations, or both, are used to assess these G x E interactions through various statistical models. In this context, this review paper explores the understanding of stability analysis in chili breeding, the significance of genotype by environment interaction, and the methods employed in this domain, providing a comprehensive update on recent advancements in stability analysis specific to chili breeding. Furthermore, research studies conducted on stability analysis in chili breeding programs and software used to assess crop stability are featured, shedding light on the application, challenges, and future prospects in the field. The importance of stability analysis in developing stable genotypes and enhancing agricultural productivity amid evolving environmental conditions is herewith underscored. These insights are critical for breeding programs aiming to create robust genotypes capable of adapting to changing environmental conditions, ultimately contributing to more sustainable agricultural practices.
Natural fibers are appealing due to its inexpensive price, small weight, and high specific modulus, renewable nature, as well as biodegradability. Bamboo fibers is one of the most promising natural fibers (along with jute, sisal, bamboo, coir, banana, and others) owing to its low cost, light weight, quick growing cycle, and wide availability. The goal of this paper is to look into fibers orientation reinforced hybrid polymer nano composites that combine BAMBOO/E-GLASS and epoxy polymer in the ratios of E-glass fibre80 percent +bamboo 20 percent, E-glass Fibre70 percent +bamboo 30 percent, and E-glass Fibre60 percent +bamboo 40 percent of volume. The mechanical characteristics will be calculated by performing tests on the specimen's tension, hardness, and flexural qualities in line with ASTM standards. Finally, the values are verified when the testing results have been obtained.

Plant diseases constitute notable threats to modern agriculture and managing them is a major challenge during crop cultivation. Plant disease management has long been one of the primary goals of any crop development program. Various traditional approaches used by the farming community such as pesticides have raised major concerns for the environment and human health. Among the biotechnological approaches used during the last two decades, RNA silencing-based resistance has been considered an important strategy for developing resistant crops. Engineered plants particularly those expressing RNA-silencing nucleotides are becoming increasingly relevant and are expected to deliver more effective solutions. Recent studies have shown that exogenous application of dsRNA targeting fungal growth and pathogenicity-related genes facilitates the reduction of pathogen and symptom expression. These findings indicate that topical application of dsRNA holds great potential in plant disease management. In this review, we explain the RNAi mechanism, methods involved in dsRNA synthesis, uptake efficiency, stability enhancement and its application. Besides, it also highlights the role of dsRNA in plant disease management and factors that influence its efficiency to offer appropriate measures.
In this present study, an attempt was made to improve the Ultimate Tensile Strength (UTS) and Microhardness (MH) of friction stir-processed AA 6082 with Ni-p surface composites without affecting the ductility of the Base Metal (BM). Ni-p micron particle with an average size of 149 mu m (99.99 purity) was utilized as reinforcement and AA6082 as a matrix for fabricating the surface composites. Process parameters namely rotational speed, transverse speed, and volume fraction with three levels considered as input parameters for this study. Moreover, ultimate tensile strength, microhardness, and wear rate were determined as process output. For this study, experiments were conducted as per Taguchi's L-9 orthogonal array (OA) by repeating each trial three times and the average values were used for further analysis. ANOVA was performed to ensure the influential process parameter and the results exhibited that the volume fraction of Ni-p exhibited the most influential parameter among the three process parameters. Additionally, Grey relational analysis (GRA) was used to grade the rank of the experimental samples using the Grey Relation Coefficient (GRC). Based on this method, the optimal process parameters (Rotational Speed = 1250 rpm, Transverse Speed = 40 mm min(-1), Volume Fraction = 18%) were chosen and the optimal sample (Rank 1) attained a UTS of 247 MPa and MH of 100 HV. The results revealed that the fabricated composite (AA6082/Ni-p) demonstrated an improvement in UTS (26.02%), MH (56.25%), and wear rate (57.38%) as compared to BM (AA6082). Eventually, the surfaces of the optimized samples were also analyzed by x-ray diffraction (XRD), energy dispersive x-ray analysis (EDAX), and field emission-scanning electron microscopy (FE-SEM) methods to confirm the composition of surface composite and the uniform distribution of particles.
A chimeric cry2AX1 gene, consisting of sequences from cry2Aa and cry2Ab genes, with insecticidal activity was employed in development of marker-free insect-resistant transgenic Bt rice. The genes of interest, cry2AX1 and hptII (selectable marker gene) were on two different T-DNAs of Agrobacterium strain, C58C1. A total of 130 hygromycin-resistant T0 transgenic rice events which were generated using two different cry2AX1 gene constructs showed positive for gusA gene. Among them, fifty events were identified as positive for cry2AX1, exhibiting a co-transformation frequency of 38.46 per cent. The expression of Cry2AX1 protein in T0 transgenic rice events varied between 0.023 and 0.133 μgg−1 of fresh leaf tissue. The larval mortality in T0 transgenic plants ranged from 20 to 95 per cent against the rice yellow stem borer (Scirpophaga incertulas) and 33.33 to 100 per cent against the rice leaffolder (Cnaphalocrocis medinalis). In T1 generation, two marker-free transgenic rice events were identified by segregation analysis. The T2 progeny plants derived from the marker-free homozygous transgenic events, expressing 0.117 μgg−1 of Cry2AX1 in fresh tissues, caused 100 per cent and 83 per cent larval mortality in rice yellow stem borer and rice leaffolder, respectively. However, in whole plant insect bioassay experiment, the larval mortality of both the target insects ranged between 10 and 50 per cent.
Bacterial Leaf Blight (Xanthomonas oryzae pv. oryzae) and blast (Magnaporthe oryzae) are the major biotic stresses around the rice-growing zones of the world. The development of resistant varieties through Marker Assisted Backcross Breeding is the utmost economical and eco-friendly method for achieving stable yield. Amongst the resistance genes recognized, Xa21 and Pi54 possess broad-spectrum resistance to many Xoo and blast strains around the world. In the present study, we have effectively introgressed a Bacterial Blight resistance gene (Xa21) and a blast resistance gene (Pi54) into susceptible variety ADT43 from RP-Bio-Patho-2 coupled with phenotypic selection for agronomic, cooking quality and grain traits through MABC. MABC was sustained till BC2F2 generation with specific markers pTA248 for Xa21 and Pi54MAS for Pi54 resistance genes. A set of SSR markers for parental polymorphism were utilized for maximum regaining of recurrent parent genome in each backcrossing. “Positive plants” from BC2F1 were selfed to generate BC2F2 and the homozygous lines for bacterial leaf blight and blast resistance genes were identified for further assessment.
The OsSPL16 (SQUAMOSA promoter-binding protein like 16) or GW8 (Grain Width 8) gene is expressed specifically in developing seeds and positively controls grain width and weight by modulating cell proliferation and enlargement in the spikelet hull of rice. OsSPL16 acts as the direct upstream suppressor of GW7 (Grain Width 7), a gene responsible for grain slenderness. The down-regulation of the OsSPL16 gene will effectively disrupt its interaction with the GW7 gene, leading to the development of slender rice grains. In our investigation, we introduced grain slenderness to a bold grain-type rice cultivar, ASD16, by employing the CRISPR/Cas9 system to knock-out the function of the OsSPL16 gene. Molecular analysis of spl16 mutants unveiled the existence of mutations within the first exon of OsSPL16, which included in-frame and frame-shift mutations. Our results demonstrated that inducing frame-shift mutations in the coding sequence of the OsSPL16 gene could effectively impart grain slenderness in bold grain varieties.
Forswearing of Service (DoS) and Denial of Service (DDoS) assaults are not kidding strings to the Internet. The recurrence of DoS and DDoS assaults is expanding step by step. Computerized instruments are additionally accessible that empower non-specialized individuals to carry out such assaults without any problem. Consequently, it isn't simply essential to forestall such assaults, yet additionally need to traceback the aggressors. Following back the wellspring of the assaults, which is known as an IP traceback issue is a difficult issue due to the stateless idea of the Internet and parodied Internet Protocol (IP) bundles. Various Internet Protocol traceback strategies present, yet they are have constraints like quantity of bundles needed or capacity computational workloads brought about at switches. A thought of an improved bundle stamping and traceback calculation for IP traceback to recognize an aggressor that works with the traceback of the parodied parcel to its starting point is proposed. The procedure proposed decreases computational time.
Emotion recognition is one of the most fascinating emerging fields of research. It’s useful in a lot of different contexts. Some of the most exciting applications of this technology involve robots’ ability to see and communicate with one another. Human emotions can be recognized through both visual and audible cues. Facial expressions are one of the most accurate indicators of a person’s emotional state. Data preprocessing, feature extraction, and model training are the first three steps of the proposed methodology. Image resizing, a median filter, noise removal, and histogram equalization are all components of preprocessing. Gaussian mixture models and the gray level co-occurrence matrix are being used for feature extraction. After the extraction of features, models with those features are trained using MA-ELM. The proposed method outperforms PCA and ELM, two of the most popular alternatives.
In this proposed approach, the system takes a look at the environmental monitoring systems that are based on the Internet of Things. The suggested system's primary function is to supply remote locations with environmental parameters via the internet. The proposed method is a practical and easy way to monitor the surrounding environment and atmosphere. The system is a representation of ambient and environmental parameter monitoring by use of low-power wireless sensors linked to the Internet that report their readings to a centralized server. Finally, data collected from all over the world may be seen on the base station remotely from any Internet-connected device.

It solves the issue of incompatible systems by providing a clear structure for exchanging information between sensors of varying measuring capabilities. This improves the effectiveness of monitoring systems. Using real-time sensors, the suggested system monitors conditions like moisture, temperature, humidity, rainfall, gas concentration, and seismic notification. An open-source platform known as Thing speak checks in on these variables every 2 minutes. The sensor data is then preprocessed, the features are selected, and the model is trained. EEMD-WOA-LSTM is used in the proposed method. When compared to two other models, including LSTM and GRU, the suggested method fares exceptionally well.
Knock out of the Starch branching Enzyme [SBE] encoding genes lead to increase in the Apparent Amylose Content in cereals. Reduced SBE activity decreases the frequency of branch points in the Amylopectin fraction, while increasing the Amylose Content [AC]. AC is positively correlated to the Resistant Starch [RS], which acts as dietary fibre leading to lowering Glycemic Index [GI]. Among the 4 Starch branching enzyme encoding genes, SBEIIb is exclusively expressed in Rice Endosperm. Therefore, in this study, the homozygous OsSBEIIb mutant lines of CO51 rice cultivar generated through CRISPR/cas9 were selected and biochemical analysis was carried out to determine the AC. Among the events studied, all the events showed a relatively increased AC as compared to the wild type. These findings highlight the need of identifying and developing rice genotypes with high RS and Amylose, which can be suitable for consumption by people suffering from diabetes, obesity, and other colon related illnesses.
Vatakantaka causes very severe pain in heal region. Vata gets aggravated and localised in Khudapradesha when person walks on unevenly or irregularly on surface. It causes difficulty to daily regular activities. It can be compared to Plantar Fasciitis as there will be stabbing (Kantaka) type of pain. Incidence is about 10% of the population, about 83% of these patients being actively working between age of 25-60 years. There is only conservative management for short term relief with certain draw backs and surgical management which increase hospital stay and high economical expenses. Acharya Sushruta described Agnikarma painful condition of Twak, Mamsa, Sira, Snayu, Asthi Sandhi. Sushruta also mentioned Siravedha of vein situated two Angulas (4cm) above the Kshipramarma in Vatakantaka. The study is aimed to compare efficacy of Agnikarma and Siravedha in Vatakantaka w.s.r plantar fasciitis. A total of 40 patients are selected and randomly divided into two groups, Group A Agnikarma in 20 patients and Group B Siravedha in 20 patients. Both group given relief in symptoms of Vatakantaka. Group A - Agnikarma (90.53%) and group – B Siravedha (88.31%) were significant in treating Vatakantaka. But Agnikarma is better effect then Siravedha in management of Vatakantaka. Both therapies can be done with less economical expenditure and minimum hospitalization.
Emerging contaminants (ECs) are substances that have been detected in water but have not been thoroughly tested or regulated. Pesticides, cosmetics, pharmaceuticals, and other medications are examples of compounds in this category. Even at low quantities, these pollutants can harm human health and the environment; therefore, avoiding them is critical. The consequences of EC pollution on the endocrine, hormonal, and genetic systems are causing significant concern. Even with current best practices and available technology, it is difficult to totally eliminate ECs from municipal and industrial wastewater treatment plants. Adsorption has been the method of choice for EC removal since it is less costly, more effective, and easier to use. To treat ECs, newer generation nanoadsorbents are employed. Adsorption was greatly enhanced by functional changes to the adsorbent surface. Carbon nanostructures are widely used as adsorbents because of their outstanding surface properties, adaptability, large surface area, adjustable structural changes, and high chemical stability. This review reviews and examines recent research on the production and use of carbon-based nanoadsorbents. The emphasis is on carbon nanotubes, graphene, and graphene-derived adsorbents. It is being investigated if these adsorbents can be used to extract hormone-disrupting chemicals and other emerging pollutants. The sources and classification of these pollutants, treatment knowledge gaps, and novel prospects for increasing carbonaceous nanoadsorbent utilization were all explored. The environmental and health problems associated with EC use are also studied.
Tomatoes are the most popular vegetable crop worldwide and contain many health-promoting compounds. Most foods contain very little amount of vitamin D, and plants are very poor sources in the production of vitamin D. The 7-dehydrocholesterol reductase gene (Sl7-DR2) is responsible for the accumulation of 7-dehydrocholesterol, which is a precursor for vitamin D3 synthesis. This gene is present in different plant species and plays a role in cholesterol metabolism as well as it links with the vitamin D pathway by inhibiting its actual function in the synthesis of cholesterol. In this study, sequencing analysis of the gene using multiple sequence alignment provided information about its similarity and their conserved sequence regions in different plant species. Using MEGA11 software, the phylogenetic analysis of this gene was done and it showed that, this gene present in chromosome 6 and chromosome 1 of Solanum lycopersicum has a close resemblance with Solanum tuberosum and Datura stramonium respectively. The physiochemical characteristics of Sl7-DR2 were analyzed by using the Expasy protparam tool. Functional annotation and secondary structure analysis of Sl7-DR2 were done using the Pfam, STRING, and SOPMA databases. The results obtained from this analysis showed that the protein was stable and has a low GRAVY Index indicating its higher affinity to water and the secondary structure analysis predicts the robust nature of this protein and the STRING analysis gave information related to proteins that are involved in the sterol pathway and their functions. These tools characterized the protein function of the Sl7-DR2 gene and studied the role of 7-dehydrocholesterol reductase in converting 7-dehydrocholesterol to vitamin D3 and its role in cholesterol metabolism. The pathway analysis using the Reactome database helps in characterizing the network between the cholesterol and vitamin D pathway. The 3D structure of the Sl7-DR2 protein was predicted using an ab initio approach, Robetta, and the predicted structure was validated using the SAVESv6.0 (PROCHECK) server. The predicted model has 90.8% of total residues present in the most favoured regions and showed high readability and quality. These analyses demonstrated the significance of this gene in the vitamin D pathway and its potential for human health in preventing various diseases.
Banana production is severely affected by the fungal wilt disease. The fungal wilt/Panama wilt disease caused by Fusarium oxysporum f. sp. cubense (Foc) causes annual yield losses ranging from 60 to 90% worldwide and 30 to 40% in India. Foc is known to exist in four important races (races 1–4), with races 1 and 4 being of much concern since they target commercial cultivars in tropical and subtropical regions and thus have received more attention. The pathogen is primarily soil-borne and saprotrophic, which makes its control extremely challenging. Genetic improvement in banana through classical breeding is difficult due to the lack of resistant germplasm and sterile nature. This chapter focuses on the various strategies that confer resistance to Fusarium wilt pathogen in banana, such as expression of PR-related genes (defensin gene), antimicrobial genes (Ace-AMP1 gene), antiapoptosis gene, and RNAi-mediated host-induced gene silencing (HIGS). Recently, genome editing has emerged as a powerful tool that can be used for mitigating challenges from biotic stresses, in general, and toward developing a sustainable disease management strategy for Fusarium wilt of banana, in particular.
