Publication A comparative evaluation of neurophysiological activity, active tactile sensibility and stereognostic ability of complete denture prosthesis, and implant-supported prosthesis wearer�A pilot study(John Wiley and Sons Inc, 2022) Bhattacharjee, Bappaditya; Saneja, Ritu; Bhatnagar, Atul; Verma, Ashish; Soni, Romesh; Singh, Ankita; Dubey, PavanAim: The study aimed to evaluate the effect of implant-supported prosthesis in completely edentulous participants in terms of osseoperception ability, neural activity, and stereognostic ability in comparison to removable prosthetic options. Materials and Methods: A total sample of 18 patients, irrespective of gender and age were allocated into three groups according to the three-treatment protocol (upper and lower complete denture, upper complete denture opposing lower implant-retained overdenture, implant-supported fixed prosthesis in both arches). Four weeks after completion of the treatment procedure active tactile sensibility (ATS) was checked by using varying thicknesses (12, 40, 80, 100, 200 ?) of articulating foils and papers. Functional magnetic resonance imaging (fMRI) was performed to record neurophysiological activity in cerebral cortex in all the participants. Various forms of test pieces (heat cure acrylic resin) were used to evaluate stereognostic ability. Data regarding the neurophysiological activity were analyzed by using Krushkal�Wallis test and p ? 0.05 was considered to be statistically significant. Data from stereognostic ability test procedure and ATS were compared by using chi-squared test and p ? 0.05 was considered to be statistically significant. Results: Statistically significant difference was found in between the articulating foils in terms of true negative responses as the foil thickness increased in participants wearing complete denture in both the arches (p�=�0.004) and implant-supported fixed prosthesis in both the arches (p�=�0.010). Participants in implant-supported fixed prosthesis group showed significantly more activation in primary motor cortex (right side), somatosensory cortex (left side), angular gyrus (both sides), temporal lobe (left) compared to other groups. No significant difference found in thalamus and premotor cortex region in between the participants of different groups. No statistically significant difference found in between the groups in terms of true responses identifying correct shapes. Mean number of correct responses in stereognostic ability test were 4.16 (83.33%), 3.5 (70%), 3.83 (76.66%) for participants of complete denture group, upper complete denture opposing lower implant retained overdenture group, and implant-supported fixed prosthesis group, respectively. Conclusion: Primary motor cortex, somatosensory cortex, and other regions of brain were diffusely activated in participants wearing implant-supported fixed prosthesis in both the arches. Less number of false responses were recorded in participants of implant-supported fixed prosthesis group and upper complete denture opposing lower implant-retained overdenture group in ATS test compared to participants wearing complete denture in both the arches. � 2022 Wiley Periodicals LLC.Publication A prospective randomized comparison of simultaneous integrated boost with sequential boost intensity-modulated radiotherapy in locally advanced head and neck cancer(Wolters Kluwer Medknow Publications, 2022) Mani, Nilesh; Aggarwal, Sushil K.; Kumar, Ishan; Mandal, Abhijit; Jaiswal, Garima; Ranjan, Rakesh; Jaiswal, Anil K.; Gupta, Neha; Singh, Ankita; Mourya, Ankur; Aggarwal, Lalit M.; Choudhary, SunilPurpose: A comparison of simultaneous integrated boost (SIB) with sequential boost (SEQ) using intensity-modulated radiotherapy along with concurrent cisplatin in locally advanced head and neck cancer (HNC) was made with regard to their survival outcomes and toxicity profile. Materials and Methods: A total of 34 patients were enrolled between October 2016 and March 2019. They were randomized into two arms, SIB and SEQB. All patients were treated with 6 MV photon beam on Linear Accelerator with weekly concurrent cisplatin at 35 mg/m 2. Overall survival (OS) and disease-free survival (DFS) were the primary end points and acute and late toxicities were the secondary end points. Results: The median follow-up period was 40.6 and 37.3 months for SIB and SEQB, respectively. At the end of 5 years, the median OS was 40.6 and 37.3 months (P = 0.947) and the median DFS was 35.1 and 37.3 months in the SIB and SEQB arms, respectively (P = 0.991).complete response at 3 months was 64.7% and 76.5% and partial response was 23.5% and 17.6%, whereas progressive disease was 11.8% and 5.9% in SIB and SEQB arms, respectively. Acute dermatitis, mucositis, dysphagia, and salivary gland toxicities were higher in the SIB arm compared to the SEQB arm. Conclusion: SIB and SEQ arms were comparable in terms of OS and DFS. However, the acute toxicities were higher in the SIB arm, although the difference was not significant, compared to the SEQB arm. � 2022 Wolters Kluwer Medknow Publications.

All of them have risen in ecosystem imbalance, climate change, global warming, and many other natural disasters as abiotic stresses. These stressors cause imbalance in physiological, biochemical, and molecular traits at different levels and under different environmental components, which they are subjected. Therefore, to diminish the catastrophic consequences on ecological sustainability, the present chapter focuses on the role and mechanisms of secondary metabolites (SMs) especially phenolic compounds (PCs) for environmental robustness diagnostics via adaption or avoidance from these stressors. The prime objective of this chapter tends to explore the functions and responses of PCs in respect to elevated CO2 (eCO2), heavy metal (HM) stress, salinity, pollutant translocations, and transformations in ecosystem. For instance, it will help in understanding the different anthropogenic stressors, their impact on environmental components, PC response, and pathway or mechanisms by which these PCs nullify the drastic consequences of anthropogenic stressors. � Springer Nature Singapore Pte Ltd. 2023.Publication Antibiotic prescribing knowledge, awareness, and attitude of dental surgeons practicing in the urban Indian population(Wolters Kluwer Medknow Publications, 2021) Rela, Rathi; Sejao, Aarti; Singh, Ankita; Singh, Prabhat; Kumar, Mukesh; Gupta, Shweta; Rangari, PriyadarshiniBackground: Studies have reported that dental procedures may serve as a portal of entry for bacteria into the blood circulation, commonly termed as bacteremia which may inhabitate the heart and joints subjected to repair and replacement by prosthesis and may lead to complications in immunocompromised patients. Dental procedure may play a pivotal role in the development of infective endocarditis and infection around the prosthetic joint. Antibiotic use is suggested for all dental procedures requiring gingival manipulation or of the periapical region of teeth or mucosal incision in these patients. Objective: The present study has been conducted to inspect the antibiotic prescribing practices of general dentists among 250 dental practitioners. Methods: The study was conducted on 250 dental surgeons practicing in the urban Indian population of various parts of the country. A validated questionnaire was developed by a multidisciplinary dental and medical team and was circulated on the subject of the basic knowledge and awareness about antibiotic prophylaxis in susceptible patients. The data from the participants were collected, collated, and statistically analyzed. Results: The present study comprised 250 dental surgeons; 178 out of 250 were male, whereas 72 were female. Antibiotic prophylaxis guidelines were followed by 169 practitioners (67.60%), whereas 81 (32.40%) dentists did not follow any guidelines. Out of 169, 67 followed the American Academy of Orthopaedic Surgeons (AAOS) guidelines (39.64%), 58 followed American Heart Association (AHA) guidelines (34.30%), whereas 44 followed general physician's guidelines (26.03%). On screening the underlying conditions for which antibiotic cover was prescribed, it was shown that majority of the dental surgeons did the same for patients with cardiac valve repair or replacement (230; 92%), followed by infective endocarditis (212; 84.80%); organ transplant (212; 84.405); diabetes (189; 75.60%); prosthetic joint replacement (150; 60%); and congenital heart defect (110; 44%). Conclusion: Patients should then be trained to perform meticulous oral hygiene and advised to schedule regular dental checkups to maintain optimal dental health. Dentists should use antibiotic prophylaxis in only conditions associated with a valid scientific basis and should follow the standard protocols recommended by the American Dental Association, AHA, or AAOS. � 2021 Journal of Pharmacy and Bioallied Sciences.

The first human dentine autograft case was done in 2002 in Japan for maxillary sinus lifting. In this clinical report, we use a hand-operated order made stainless steel apparatus to crush the tooth and prepare the DDM chair side. Chemical treatment of DDM particulate was done for demineralization and sterilisation purpose, and used immediately as a graft material for socket preservation. Dentascan after 4 month showed remarkable bone at the site of grafting and implant was placed. The patient was restored successfully with their own DDM and implant-supported prosthesis. � 2023 National Journal of Maxillofacial Surgery.Publication Brassinosteroids and their analogs: Feedback in plants under in vitro condition(Elsevier B.V., 2021) Singh, Ankita; Dwivedi, Padmanabh; Kumar, Vijay; Kumar Pandey, DevendraBrassinosteroids (BRs) are the sixth important plant hormones that induce their effect at micro-level concentration. The importance of its analogous under in vitro condition for many studies includes the study of response in plants aimed at improving various developmental, physiological, morphological, biochemical processes without the involvement of climatic factors, nutrients and diseases. BR improves and increases regeneration and multiplication rate by induction of callus growth, somatic embryos, tracheary elements, shoot elongation, formation of 2embryogenic tissue, stimulation of branch elongation, etc. These provide rapid disease-free clonal propagation of improved varieties within less time and space. BRs improve photosynthetic processes, antioxidant enzymes activities, synthetic seed production and elicitation of secondary metabolites production. Most importantly, it provides resistance from abiotic stresses, for example, oxidative and salinity stress. This review summarizes role of brassinosteroid and its various analogs in improving different morphological, physiological and biochemical attributes in various crop plants grown in vitro, both under normal as well as abiotic stress conditions. � 2021 SAABPublication Dose at posterior-inferior border of symphysis point: A predictor for vaginal stricture in cervical cancer(Elsevier Inc., 2023) Singh, Ankita; Mani, Nilesh; Aggarwal, Lalit M.; Agarwal, Sumit; Mourya, Ankur; Verma, Ashish; Bagchi, Antara; Gupta, Neha; Choudhary, SunilPURPOSE: To study the effect of various dose-volume parameters on the severity of vaginal stricture (VS) and the correlation of the latter with the posterior-inferior border of symphysis (PIBS) points in locally advanced cervical cancer patients treated with concurrent chemoradiation and brachytherapy. METHODS AND MATERIALS: A prospective study was done on 45 histologically proven locally advanced cervical cancer patients between January 2020 and March 2021. All of them were treated with concurrent chemoradiation with 6 MV photon linear accelerator to a dose of 45 Gy/25 fractions in 5 weeks. Twenty-three patients were treated with intracavitary brachytherapy with a dose of 7 Gy/fraction/week for three fractions. Twenty-two patients were treated with interstitial brachytherapy, with 6 Gy/fraction for four fractions, each fraction 6 h apart. Grading of VS was done as per Common Terminology Criteria for Adverse Events version 5. RESULTS: The median followup was 21.5 months. About 37.8% of patients had VS with a median duration of 8.0 months (4.0�12 months). About 22.2% had Grade 1, 6.7% had Grade 2, and 8.9% had Grade 3 toxicity. Doses at PIBS and PIBS?2 points had no correlation with vaginal toxicity, however, the dose at PIBS+2 was significantly associated with VS (p = 0.004). The treated length of the vagina at the time of brachytherapy (p = 0.001), initial tumor volume (p = 0.009), and vaginal involvement after completion of external beam radiotherapy (EBRT) (p = 0.01) were also statistically significant with the development of VS of Grade 2 or more. CONCLUSIONS: Dose at PIBS + 2, treated length of the vagina with brachytherapy, initial tumor volume, and post-EBRT vaginal involvement are strong predictors for the severity of VS. � 2023 American Brachytherapy SocietyPublication E-learning during the COVID-19 Pandemic in Various Healthcare Institutes of India(Wolters Kluwer Medknow Publications, 2022) Kumar, Surender; Singh, Bishnupati; Mahuli, Amit Vasant; Singh, Ankita; Mahadevan, Vallabh; Ranjan, MadhuIntroduction: A multicentric study on the benefits and outcomes of e-learning was lacking during the pandemic.

Being an unusual malignancy, there is limited Indian data regarding survival outcomes and prognostic factors. Aim: To evaluate survival outcomes and associated prognostic factors in patients with carcinoma anal canal treated with radical intent. Methods and Material: Patients with squamous cell carcinoma of the anal canal, treated with radical intent between 2015 and 2019 were included in the study. Data regarding the baseline characteristics of the patients and treatment outcomes were collected and analyzed. Survival rates were estimated using Kaplan-Meier method. To determine survival difference between the groups, log-rank test was used. Multivariate analyses were performed with Cox proportional hazard models and P value < 0.05 was considered significant. Results: Forty-two patients were identified after applying suitable eligibility criteria. The median age was 55 years (range: 26-80 years).The median follow-up duration was 23.5 months (range: 1.9-51.9 months). The 3-year overall survival (OS), disease-free survival (DFS), and locoregional (LRC) were 78.5%, 53.1%, and 66.4%, respectively. On multivariate analysis, inferior DFS was significantly affected by lack of concurrent chemotherapy (CT) (hazard ratio [HR], 11.50; 95% confidence interval [CI], 1.92-68.78; P = 0.007) and radiotherapy (RT) dose of 45 Gy or less (HR, 35.96; 95% CI, 6.32-204.56; P = 0.000). Conclusion: For patients of carcinoma anal canal, concurrent CT and RT dose are independent prognostic factors influencing DFS. � 2023 Copyright:Publication Exogenous Melatonin Counteracts Salinity and Cadmium Stress via Photosynthetic Machinery and Antioxidant Modulation in Solanum lycopersicum L(Springer, 2023) Bhardwaj, Kritika; Raina, Meenakshi; Sanfratello, Giovanni Marco; Pandey, Prashasti; Singh, Ankita; Rajwanshi, Ravi; Negi, Neelam Prabha; Rustagi, Anjana; Khushboo; Kumar, DeepakBeing sessile, plants� exposure to various environmental stresses during their life cycle is inevitable which can affect their yield and productivity. This study investigates the protective effect of exogenous application of melatonin on 30-day-old tomato plants under NaCl and cadmium stress treatments. Plant growth, photosynthetic pigment, and antioxidant enzymes of plants exposed to NaCl, cadmium (Cd), and NaCl + Cd stress and melatonin treatment on them were analysed. The plants under NaCl- and Cd-induced stress produced an increased amount of ROS and lipid peroxidation, which were significantly reduced upon melatonin application. The maximum quantum energy (FV/FM) and performance index (PIABS) significantly improved in melatonin-treated plants under stress conditions. Redox homeostasis was maintained with a significant increase in superoxide dismutase, catalase, ascorbate peroxidase, and glutathione reductase. This study suggests that exogenous melatonin improves plants� ability to overcome the combination stress caused by NaCl and Cd by increasing overall photosynthetic capacity and modulating redox balance. � 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.Publication How the soil nitrogen nutrient promotes plant growth�a critical assessment(Elsevier, 2022) Singh, Ankita; Hidangmayum, Akash; Tiwari, Pushpendra; kumar, Vivek; Singh, Bansh Narayan; Dwivedi, PadmanabhNitrogen is a principal constituent of proteins, amino acids, and nucleotides involved in several physiological responses like seed germination, root growth, flowering, and crop production. The plant required N in the form of NO3? or/and NH4+ for high-yield crop production. The mechanism of root adaptation is varied in the supply of N forms, and concentration has been well characterized and demonstrated. However, the effects of soil N concentration on plant development and yield production are limited and widely diverse in the literature. In this review, we summarize the role of forms of nitrogen and plant growth-promoting microbes as a biofertilizer whose implementation in fields shapes plant development and crop production. The presence of external NO3? induces a family of nitrate and ammonium transporters genes and provokes lateral root differentiation. But contrast, excess N supply could suppress the root differentiation and expression of nitrate transporters. The effects of biofertilizer in the presence of nitrate supply showed a similar response as demand for low N supply. Therefore, optimum management of N is needed to minimize N losses in soil and gain maximum crop outcome. There are several approaches, such as soil monitoring, tissue N analysis, and crop-based methods can contribute to balancing N in the soil-crop-atmosphere. The implementation of such packages, when combined with biofertilizer, irrigation requirements, and soil N monitoring methods, is vital for well-organized N management with minimizing N loss to the environment. � 2022 Elsevier Inc.

In this paper, we examine the quantum confinement and phonon anharmonicity of different-layered MoS2, synthesized via the chemical vapor deposition technique. We explore the contribution of spin-orbit and interlayer couplings both theoretically (first-principles density functional theory) and experimentally (Raman and photoluminescence spectroscopies). Further, we demonstrate the thermally driven layer-dependent bandgap tunability in (1L, 3L, and 5L) triangular MoS2 grown over the SiO2/Si substrate. We have also scrutinized their phonon confinement behavior and thermal response in a low-temperature regime (80-300 K) using the optothermal Raman spectroscopy technique. A semiquantitative model comprising the volume and temperature effect provides insights into the nonlinear temperature-dependent phonon anharmonicity, revealing that the contribution of higher order (three) phonon scattering reduces with increasing layer numbers in MoS2. We further measure the interfacial thermal conductance (g) and thermal conductivity (ks) of synthesized MoS2, and the obtained values of g (and ks) are observed to increase (and decrease) with increasing layer number. Our study will advance the understanding of anharmonic behavior of phonons in different-layered MoS2 nanostructures for designing MoS2-based next-generation devices for various applications. � 2023 American Chemical Society.Publication Molecular advances in plant root system architecture response and redesigning for improved performance under unfavorable environments(Elsevier, 2021) Indu; Lal, Dalpat; Dadrwal, Basant Kumar; Saha, Debanjana; Chand, Subhash; Chauhan, Jyoti; Dey, Prajjal; Kumar, Vivek; Mishra, Udit Nandan; Hidangmayum, Akash; Singh, Ankita; Singhal, Rajesh KumarA future challenge in crop improvement, mostly driven by global unfavorable environment variables, is to develop climate smart crops that are competent for multiple biotic and abiotic stresses. Researchers have addressed the elementary mechanism focused on aboveground plant organs, as extensive study on root traits are very confined. Moreover, most of our knowledge regarding root research is limited to certain developmental aspects, while a direct connectivity to developing environment sensitive roots under various stresses is extremely urgent to explore thoroughly. Therefore this chapter covers the most recent research on the root system architecture (RSA) of different crop species with regard to different extreme environmental variables such as high temperature, elevated CO2, low temperature, drought, excess water, and stressed soil. We highlight the recent physiological, genetic, and molecular strategies used in the rapid advancement of RSA traits under these stresses. There is an urgent need to explore RSA in order to improve crop stress tolerance, therefore we discuss and explore the link between RSA and stress tolerance. Further, this chapter will provide new insights into the relevance of the redesign and selection of improved RSA for the development of climate resilient plants. We conclude by discussing the functional and molecular evidence of RSA components such as deep root weight, root length density, root volume, root penetration, and other root traits for improving root plasticity in a fluctuating environment, which will help the researchers to select RSA pipelines for abiotic stress resilience and crop improvement programs. � 2021 Elsevier Inc.

However, it alters the quantity and grain quality of agricultural products and also dwindles the soil and environment sustainability. Therefore, it is imperative necessity to explore novel, emerging, highly efficient, and ecofriendly approaches, which can provide a balanced diet to the next generation. In this context, nanotechnology in the agriculture sector is moving towards achieving the goal of future sustainability. Seed priming with nanochemicals or green chemicals such as plant growth promoting rhizobacteria (PGPR) represents one of the emerging, cost-effective, and environmentally friendly approaches to enhance the crop production with the use of minimum inputs and higher utilization of primary resources (light, water, and nutrients) under adverse climatic and soil conditions. The nanopriming [seed treatment with nanoparticles (NPs) before sowing] with green chemicals such as chitosan, micronutrients (Fe, Zn, Cu), and inorganic and organic compounds (PGPR hormones) has shown dynamic and excellent results during seed germination, vegetative phase, reproductive phase and in grain quality attributes. This approach is very efficient in improving nutrient use efficiency (via enhancing nutrient absorption, transport, and partitioning to reproductive parts), water use efficiency (via enhanced water uptake and utilization), assimilated partitioning, and other resource use efficiencies, which reduces the extra load of fertilizers, pesticides, and other agrochemicals used in the cultivation of crops. Moreover, nanopriming improves the plant antioxidant defense via improving stress genes and proteins, antioxidant chemicals, and signaling compounds, which ultimately reduce the energy load of the crop during adverse situations. To realize the importance of nanopriming, this chapter explores the recent advances and achievements made under unfavorable situations, future challenges, and prospects to improve the depth of knowledge regarding NP mechanism�s to accomplish the central goal of sustainability for farmers, scientific communities, and our future generation. � 2022 Elsevier Inc.

Finite Element Analysis (FEA) a newly innovated technology has been used in dental implantology to evaluate stress distribution patterns. There is little evidence available regarding the stress distribution in peri-implant region for implant supported overdentures. The purpose of the review was to generate scientific evidence on peri-implant stress distribution in FEA model with different types of attachments employed in implant supported overdentures. Materials and methods: Systematic review was conducted as per the Preferred Reporting Items for Systematic Reviews Guidelines and Meta-Analyses statement (PRISMA). A comprehensive search was undertaken by two reviewers from January 2020 to June 2020 with no year limits to published articles. Only in-vitro FEA studies were included. Following electronic databases were searched for published studies- PubMed, Web of Science. Characteristics of the studies tabulated and analysis of articles was done to compare different attachment systems. Results: Locator attachments showed better stress distribution than ball attachment system in all the studies but one. Two studies showed results in favour of ball attachment compared to bar-clip attachment system when stress was evaluated distal to the implants. No significant difference in terms of stress concentration could be generated between ball versus magnetic/equator versus locator attachment system due to less number of studies and conflicting results. Conclusion: Various studies showed different results due to heterogenicity in selected attachment systems and study designs. Locator attachments showed favourable stress distribution around peri-implant bone than other attachments. � 2022 Craniofacial Research FoundationPublication Physiological, biochemical, and molecular mechanisms of gasotransmitter-mediated heavy metal stress tolerance in plants(CRC Press, 2021) Kumar, Vivek; Hidangmayum, Akash; Singh, Ankita; Sodani, Rekha; Dadrwal, Basant Kumar; Kumar, Navneet; Chaudhary, Surendra Kumar; Chaudhary, Brijesh Kumar; Kushwaha, S.P.; Chauhan, Jyoti; Anuragi, Hirdayesh; Mishra, Udit Nandan; Lenka, Devidutta; Singhal, Rajesh Kumar[No abstract available]Publication Smap soil moisture product assessment over wales, u.K., using observations from the wsmn ground monitoring network(MDPI, 2021) Gupta, Dileep Kumar; Srivastava, Prashant K.; Singh, Ankita; Petropoulos, George P.; Stathopoulos, Nikolaos; Prasad, RajendraSoil moisture (SM) is the primary variable regulating the soil temperature (ST) differences between daytime and night-time, providing protection to crop rooting systems against sharp and sudden changes. It also has a number of practical applications in a range of disciplines. This study presents an approach to incorporating the effect of ST for the accurate estimation of SM using Earth Observation (EO) data from NASA�s SMAP sensor, one of the most sophisticated satellites currently in orbit. Linear regression analysis was carried out between the SMAP-retrieved SM and ground-measured SM. Subsequently, SMAP-derived ST was incorporated with SMAP-derived SM in multiple regression analysis to improve the SM retrieval accuracy. The ability of the proposed method to estimate SM under different seasonal conditions for the year 2016 was evaluated using ground observations from the Wales Soil Moisture Network (WSMN), located in Wales, United Kingdom, as a reference. Results showed reduced retrieval accuracy of SM between the SMAP and ground measurements. The R2 between the SMAP SM and ground-observed data from WSMN was found to be 0.247, 0.183, and 0.490 for annual, growing and non-growing seasons, respectively. The values of RMSE between SMAP SM and WSMN observed SM are reported as 0.080 m3m?3, 0.078 m3m?3 and 0.010 m3m?3, with almost zero bias values for annual, growing and non-growing seasons, respectively. Implementation of the proposed scheme resulted in a noticeable improve-ment in SSM prediction in both R2 (0.558, 0.440 and 0.613) and RMSE (0.045 m3m?3, 0.041 m3m?3 and 0.007 m3m?3 ), with almost zero bias values for annual, growing and non-growing seasons, respectively. The proposed algorithm retrieval accuracy was closely matched with the SMAP target accuracy 0.04 m3m?3 . In overall, use of the new methodology was found to help reducing the SM difference between SMAP and ground-measured SM, using only satellite data. This can provide important assistance in improving cases where the SMAP product can be used in practical and research applications. � 2021 by the authors.

Nearly all lower and higher microorganisms belong to taxa have mutualistic symbiosis association with microorganisms. It is believed that they have co-evolved with their microbiota based on its functions ability like metabolism, nutrition, and immunity. They colonize in the different compartment of plant that contains the second plant�s genome. It has impressive functional ability to enhance plant growth development and crop production in the current resilient climatic challenges. Therefore, it is need to seek the diversity of plant microbiome and bring to in agricultural practice. Several approaches have been implemented to improve microbiome existence. In another way, the microbial consortium can be applied; however, innovative approaches in the field is urgently required. New, useful and smart knowledge would be preferred for selection of microorganisms, and their delivery method and formulations. Though, plant genotype variation and farming practices influencing the plant microbiome communities and their functioning. Therefore, the selection of appropriate plant breeding and cropping practices leading to improved microbiome-based plant development and crop production. Several studies have heightened that plant-microbe interactions not only improved plant growth and health but also for sustainable crop production in the changing environmental scenario. This research topic covers information about plant microbiome status, functionalities, and their implementation in agricultural practices, and focuses on information gaps in this emerging research fields. � 2022 Elsevier Inc.
