Anthropogenic Stress and Phenolic Compounds: An Environmental Robustness Diagnostics Compound Family in Stress Ameliorations
(Springer Nature, 2023) Vivek Kumar; Rajesh Kumar Singhal; Akash Hidangmayum; Ankita Singh; Bhayyalal Aanjna; Jyoti Chauhan; Bandana Bose
Natural ecosystems are progressively vulnerable to a number of multiple anthropogenic stressors, particularly with water, ozone, air pollutants, pesticides, heavy metals (HMs), deforestation, artificial lightening, agriculture intensification, and land use pattern changes. 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.
Application of chitosan on plant responses with special reference to abiotic stress
(Springer, 2019) Akash Hidangmayum; Padmanabh Dwivedi; Deepmala Katiyar; Akhouri Hemantaranjan
Chitosan is a natural biopolymer modified from chitins which act as a potential biostimulant and elicitor in agriculture. It is non-toxic, biodegradable and biocompatible which favors potentially broad application. It enhances the physiological response and mitigates the adverse effect of abiotic stresses through stress transduction pathway via secondary messenger(s). Chitosan treatment stimulates photosynthetic rate, stomatal closure through ABA synthesis; enhances antioxidant enzymes via nitric oxide and hydrogen peroxide signaling pathways, and induces production of organic acids, sugars, amino acids and other metabolites which are required for the osmotic adjustment, stress signaling, and energy metabolism under stresses. It is also known to form complexes with heavy metals and used as tool for phytoremediation and bioremediation of soil. Besides, this is used as antitranspirant compound through foliar application in many plants thus reducing water use and ensures protection from other negative effects. Based on such beneficial properties, chitosan is utilized in sustainable agricultural practices owing to changing climates. Our review gathers the recent information on chitosan centered upon the abiotic stress responses which could be useful in future crop improvement programs. © 2019, Prof. H.S.

Chitosan Based Nanoformulation for Sustainable Agriculture with Special Reference to Abiotic Stress: A Review
(Springer, 2022) Akash Hidangmayum; Padmanabh Dwivedi
Chitosan is a naturally occurring biological macromolecule and second most abundant polysaccharide next to cellulose, derived from deacetylation of chitin. Due to its biocompatibility, biodegradability, nontoxic and broad spectrum of antimicrobial activity, it has become an important field of drug delivery system study. With the advancement in nanotechnology, chitosan based nanoformulations have sought considerable attention in agricultural sciences. The first part of this review focuses on the overview of chitosan and its nanoparticles, its different mode of synthesis and challenges, and controlled release mechanism of encapsulated molecules. The subsequent section focuses on the uptake and translocation of chitosan based nanoformulation including plant growth, nutrition and special focus on abiotic stress mitigation strategies. We conclude that chitosan based nanoformulation holds great promises in encapsulating bioactive molecules for controlled release thus reduces environmental hazard, and improves plant growth, yield and subsequently mitigates various biotic and abiotic stresses. Chitosan based nanoformulations have good controlled release behaviour and long stability of bioactive compounds encapsulated inside chitosan nanoparticle, and have prosperous future for improving agricultural productivity in the era of climate change. © 2021, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

(Springer Science and Business Media B.V., 2022) Diksha Kumari; Bishun Deo Prasad; Padmanabh Dwivedi; Akash Hidangmayum; Sangita Sahni
Several phytopathogens have detrimental effects on crop production and productivity potentially threatening global food security. Studying the genetic mechanisms of virulence in phytopathogens is vital to assist in their management. Genome editing tools are paving their fascinating roles from the first-generation site-specific nucleases ZNF and TALEN to the current generation clustered regularly interspaced short palindromic repeat (CRISPR)/CRISPR-associated protein9. The discovery of CRISPR/Cas9 has revolutionised the understanding of resistance as well as the susceptibility mechanism against phytopathogens in crop plants. This emerging tool allows researchers to perform precise genome manipulation, genetic screening, regulation, and correction to develop resistance in crop plants with fewer off-target effects. It provides a new opportunity for disease improvement and strengthens the resistant breeding programme. CRISPR/Cas9-based targeted gene manipulation and its enormous application potential as well as the challenges for developing transgene-free disease-resistant crop plants have been discussed in this review. © 2022, The Author(s), under exclusive licence to Springer Nature B.V.
Effect of chitosan seed priming on mungbean seedlings subjected to different levels of water potential
(Institute for Ionics, 2023) Akash Hidangmayum; Padmanabh Dwivedi
The main focus of our experiment was to understand the ameliorative effect of chitosan seed priming on different levels of water potential (water stress). Treatment with three levels of polyethylene glycol (PEG) induced water stress (− 0.3, − 0.4, and − 0.5 MPa) reduced seedling parameters, such as germination, mean germination time, shoot length, root length, fresh weight, dry weight, chlorophyll content, α-amylase, and caused lipid peroxidation through increased MDA content. Seedlings treated with chitosan (0.15%) improved all the basic morpho-physiological attributes. Also, in seedlings subjected to stress condition, treatment with chitosan alleviated the water stress which is reflected through increased antioxidative system such as SOD and CAT, increased proline level, reduced MDA accumulation and increased activity of α-amylase, offering strong defense mechanism, stress-protective metabolites, and better seed storage mobilization so as to facilitate seed germination ability and overall improved growth with higher tolerance to water stress. Meanwhile, the histochemical localization of H2O2 and superoxide radical O2− showed reduced accumulation of ROS in chitosan-treated leaves. The results indicated that chitosan treatment alleviated the adverse effects of water stress imposed at three levels of water potential. © 2022, The Author(s) under exclusive licence to Franciszek Górski Institute of Plant Physiology, Polish Academy of Sciences, Kraków.
How the soil nitrogen nutrient promotes plant growth—a critical assessment
(Elsevier, 2022) Ankita Singh; Akash Hidangmayum; Pushpendra Tiwari; Vivek kumar; Bansh Narayan Singh; Padmanabh Dwivedi
Nitrogen 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.

(Springer Singapore, 2019) Bansh Narayan Singh; Mahendra Vikram Singh Rajawat; Akash Hidangmayum; Waquar Akhter Ansari; Devendra Singh; Mohammad Tarique Zeyad; Shiv Charan Kumar; Manish Roy; Murugan Kumar
Due to the use of a large amount of chemical fertilizers, continuous loss of soil fertility puts pressure on farmers toward more crop production in a sustainable manner. This problem creates a big challenge for farmers to fulfill the demand for the next generation. If an adequate amount of fertilizers is not supplied to crops, it raises major issue related to global food production and food security. Therefore, it requires adapting an eco-friendly, sustainable, and cost-effective approach for agricultural practices without arising environmental issues. Several natural rhizobacteria inhabiting the rhizospheric soil exist, which are used for plant growth promotion. They have tremendous capacity to provide directly or indirectly nutrient availability to the plants, stimulate plant hormones, and secrete certain compounds that help in the association of several other beneficial microbes with plant roots. In addition to restoring soil fertility, they have the capability to protect plants against soil-borne pathogens, thereby promoting plant growth. Further, application of plant growth-promoting rhizobacteria reduces the utilization of chemical fertilizers, pesticides, and other artificial growth regulators that cause severe health and environmental issues, soil infertility, water pollution, and biodiversity losses. In this context, sustainable use of rhizobacteria has been suggested to be an eco-friendly and cost-effective approach which increases crop yields and directly or indirectly protects plant from soil-borne pathogens for a long time. © Springer Nature Singapore Pte Ltd. 2019.
Mechanisms and applicability of nanotechnology-mediated beneficial microbes in mitigation of salinity stress in plants
(Elsevier Masson s.r.l., 2025) Sudhir K. Udpadhay; Akash Hidangmayum; Devendra Jain; Padmanabh Dwivedi
Soil salinity is a major abiotic-stress that severely impacts global agricultural productivity by reducing plant's water-uptake, causing ion toxicity, and disrupting metabolic balance. Beneficial microorganisms, including plant growth-promoting rhizobacteria (PGPR) and fungi, play a remarkable role in mitigating salt-stress through mechanisms such as osmotic adjustment, ion homeostasis, phytohormone regulation, and antioxidant defense systems. Under very high salinity, microbial inoculants also often suffer from poor survival rates, ineffective root colonization, and uneven field performance. Recent developments in nanotechnology have brought fresh approaches to maximize microbial effectiveness, therefore, offering better defense against environmental stresses and enhancing plant-microbe interactions. Under salt stress, engineered nanomaterials including nanocarriers and nano-formulations improve microbial viability, enable regulated administration, and induce biofilm formation, thereby strengthening plant resistance. Furthermore, nanoparticles enhance stress tolerance systems by modulating critical signal transduction pathways and inducing genomic and proteomic changes in microorganisms. Despite these promising benefits, concerns regarding nanoparticle toxicity, environmental persistence, regulatory challenges, and economic feasibility remain largely unaddressed. Comprehensive risk analyses and the creation of environmentally benign, biodegradable nanomaterials are necessary given the possible long-term effects mediated nanoparticles on microbial populations, soil's quality, and including crop's safety. This review explores emerging trends in nano-enabled agricultural applications, critically assesses the mechanistic contribution of nanotechnology in reducing microbial-mediated salinity stress, and addresses important issues and future research directions for the sustainable deployment of nanotechnology in plant stress management. © 2025 Elsevier Masson SAS

A 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.

(Elsevier, 2022) Basant Kumar; Indu; Rajesh Kumar Singhal; Subhash Chand; Jyoti Chauhan; Vivek Kumar; Udit Nandan Mishra; Akash Hidangmayum; Ankita Singh; Bandana Bose
Diversified anthropogenic activities including intense farming (farm mechanization, high dose of fertilizer, and agrochemicals) increase the productivity and production of the agriculture sector. 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.

(Elsevier, 2021) Asha Kumari; Binny Sharma; Bansh Narayan Singh; Akash Hidangmayum; Hanuman Singh Jatav; Kailash Chandra; Rajesh Kumar Singhal; Eetela Sathyanarayana; Abhik Patra; Kiran Kumar Mohapatra
Presently, the world is suffering from the declining trend of crop yields globally, making food security a major challenge. The limited availability of arable land and water resources has made this challenge even bigger. Recent research-based studies depict that, in many developing countries, poor soil fertility, lower availability of mineral nutrients in soil, improper nutrient management, along with the lack of plant genotypes having high tolerance to nutrient deficiencies or toxicities are major constraints leading to food insecurity, malnutrition (i.e., micronutrient deficiencies), and degradation of ecosystem. It has been stated that 60% of our cultivated soils have growth-limiting problems with deficiencies and toxicities of available mineral nutrients. About 50% of the world population suffers from micronutrient deficiencies that make mineral nutrition studies a major promising area in meeting the global demand for sufficient food production with enhanced nutritional value. Integration of plant adaptation strategies in such soils using genetics and plant breeding and molecular biology is indispensable in developing plant genotypes with high genetic potential to acclimatize such nutrient-deficient and toxic soil conditions to translocate more micronutrients into edible plant parts such as cereal grains. Thus, plant nutrition research provides invaluable information, which is highly useful in elimination of these constraints, and leads to sustain the food security and well-being of humans without harming the environment. Keeping all these points in mind this chapter helps in understanding the mechanisms and strategies of plant in nutrient-deficient and toxic soil conditions. © 2022 Elsevier Inc. All rights reserved.

Seed Priming and Foliar Application of Chitosan Ameliorate Drought Stress Responses in Mungbean Genotypes Through Modulation of Morpho-physiological Attributes and Increased Antioxidative Defense Mechanism
(Springer, 2023) Akash Hidangmayum; Padmanabh Dwivedi; Prasann Kumar; Sudhir Kumar Upadhyay
Drought is one of the important abiotic stress factors that affect crop productivity worldwide. In recent years, applications of biopolymer chitosan on plants have received attention due to their biostimulant activity and ability to elicit a defense response to stress. The current study investigates the effect of seed priming and foliar application, or both, under drought stress in pot experiments. The optimal concentration of chitosan was determined through morpho-physiological attributes and carried forward for seed priming and foliar application under drought stress in pot experiments for two consecutive years. Morpho-physiological, biochemical and yield attributes were investigated in two genotypes of mungbean which were previously screened for drought tolerant and susceptibility. Results revealed that drought stress considerably reduced plant growth parameters, relative water content, and increased oxidative stress markers such as proline, H2O2 and MDA leading to reduced yield attributes. However, chitosan application significantly mitigates these effects. Both seed priming and foliar-applied chitosan in both the genotypes significantly improved all the studied parameters through increased antioxidant enzymes like SOD, CAT and APX in drought stress plants. The combination of both seed priming and foliar application of chitosan most significantly improved drought-induced responses which are reflected through improvement in morpho-physiological, biochemical attributes, increased antioxidative enzyme activities and improved yield in both the tolerant and susceptible genotypes. © 2022, The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature.

(Springer Singapore, 2019) Bansh Narayan Singh; Akash Hidangmayum; Ankita Singh; Shailendra Singh Shera; Padmanabh Dwivedi
Owing to its outstanding contribution in promoting plant growth and mitigating environmental stresses through activating different defense mechanisms, a root-colonizing endophytic fungus Piriformospora indica has received great attention from researchers over the past three decades. Piriformospora indica is a cultivable fungus which demonstrates its adaptability of colonizing a broad spectrum of plant species through secretion/alteration of secondary metabolites and host hormone signaling pathways during the course of root association. Association of Piriformospora indica with plant roots leads to an improved plant performance like proliferation by indole-3-acetic acid production and nutrient acquisition subsequently leading to improved crop growth and production. Furthermore, its metabolites reprogram the root association which stimulates both local and systemic resistance against plant diseases through signal transduction. In this review, we focus on the importance of secondary metabolites of Piriformospora indica, limited not only in plants but also in animal system. © Springer Nature Singapore Pte Ltd. 2019.

(Elsevier, 2022) Ankita Singh; Akash Hidangmayum; Bhudeo Rana Yashu; Vivek Kumar; Bansh Narayan Singh; Padmanabh Dwivedi
Bacteria had arisen a long time before the development of multicellular eukaryotic organisms, and they are quickly adapted in a new niche. 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.

Uptake, Accumulation, and Toxicity of Nanoparticles in Plants
(Taylor and Francis, 2025) Akash Hidangmayum; Akankhya Guru; Jyotsna Setty; Padmanabh Dwivedi
The growing unsustainable use of chemicals and hazardous compounds coupled with the rising climate change makes the use of nanoparticles (NPs) in sustainable agriculture essential. As a nanopesticide, nanofertilizer, and nanosensor in crop growth and production, nanotechnology has amply demonstrated its agricultural uses. Due to their nanosize, sustained release, and site-specific delivery, they are useful tools for smart agriculture. The earlier studies have demonstrated that the interaction between plant species and NPs is a complex but ongoing dynamic process. Both the type of plant and the characteristics of the NP, such as its component, encapsulating materials, shape, size, dose, surface chemistry, etc., affect this interaction. The chapter provides a thorough explanation of the uptake, translocation, accumulation, and toxicity of NPs within plants, as well as the mechanisms underlying these processes. © 2025 selection and editorial matter, Mary Theresa, Ashitha Jose, Jyotishkumar Parameswaranpillai, Radhakrishnan E K; individual chapters, the contributors.
