Item Valorization of fish processing industry waste for biodiesel production: Opportunities, challenges, and technological perspectives(Elsevier Ltd, 2023-11-09T00:00:00) Jaiswal, Krishna Kumar; Dutta, Swapnamoy; Banerjee, Ishita; Jaiswal, Km Smriti; Renuka, Nirmal; Ratha, Sachitra Kumar; Jaiswal, Amit K.The fish industry is one of the fastest-growing industries in the world, which generates massive waste, and its unsafe disposal may pose severe health and environmental hazards. Thus, the valorization of fish waste has attracted the scientific community's attention due to its dual benefits of waste management and resource recovery. This waste has been reported as a suitable feedstock for various industrial uses such as biodiesel, biogas, animal feeds, dietary foodstuffs, food packaging, cosmetics, and catalysts. Fish waste for biodiesel production has become attractive due to its rich oil content. There are some significant limitations of using fish waste for biodiesel production, such as oil content and quality variations depending on the fish type and processing methods. Despite this, fish waste remains a promising feedstock due to the presence of more easily biodegradable organic compounds than other conventional lignocellulosic substrates. Recently, a few industries have also implemented fish oil technology for biodiesel production at a demonstration scale to establish a biorefinery. However, biodiesel production from fish wastes is challenging due to different factors, such as finding efficient and economically viable techniques to extract fish oil and transesterification. This review work has intended on the prospects and challenges of the potential of fish processing wastes to convert into biodiesel. Different extraction procedures, factors affecting transesterification, characteristics of biodiesel, and industrial opportunities have been comprehensively discussed. � 2023 Elsevier LtdItem Rethinking underutilized cereal crops: pan-omics integration and green system biology(Springer Science and Business Media Deutschland GmbH, 2023-09-30T00:00:00) Rahim, Mohammed Saba; Sharma, Vinita; Pragati Yadav; Parveen, Afsana; Kumar, Adarsh; Roy, Joy; Kumar, VinayMain conclusion: Due to harsh lifestyle changes, in the present era, nutritional security is needed along with food security so it is necessary to include underutilized cereal crops (UCCs) in our daily diet to counteract the rising danger of human metabolic illness. We can attain both the goal of zero hunger and nutritional security by developing improved UCCs using advanced pan-omics (genomics, transcriptomics, proteomics, metabolomics, nutrigenomics, phenomics and ionomics) practices. Abstract: Plant sciences research progressed profoundly since the last few decades with the introduction of advanced technologies and approaches, addressing issues of food demand of the growing population, nutritional security challenges and climate change. However, throughout the expansion and popularization of commonly consumed major cereal crops such as wheat and rice, other cereal crops such as millet, rye, sorghum, and others were impeded, despite their potential medicinal and nutraceutical qualities. Undoubtedly neglected underutilized cereal crops (UCCs) also have the capability to withstand diverse climate change. To relieve the burden of major crops, it is necessary to introduce the new crops in our diet in the way of UCCs. Introgression of agronomically and nutritionally important traits by pan-omics approaches in UCCs could be a defining moment for the population�s well-being on the globe. This review discusses the importance of underutilized cereal crops, as well as the application of contemporary omics techniques and advanced bioinformatics tools that could open up new avenues for future study and be valuable assets in the development and usage of UCCs in the perspective of green system biology. The increased and improved use of UCCs is dependent on number of factors that necessitate a concerted research effort in agricultural sciences. The emergence of functional genomics with molecular genetics might gear toward the reawakening of interest in underutilized cereals crops. The need of this era is to focus on potential UCCs in advanced agriculture and breeding programmes. Hence, targeting the UCCs, might provide a bright future for better health and scientific rationale for its use. � 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.Item Microbe-Assisted Bioremediation of Pesticides from Contaminated Habitats: Current Status and Prospects(CRC Press, 2023-10-19T00:00:00) Reddy, Karen; Jose, Shisy; Fayaz, Tufail; Renuka, Nirmal; Ratha, Sachitra Kumar; Kumari, Sheena; Bux, FaizalPesticide use is expanding worldwide due to a continuous increase in agricultural intensification in order to meet the global food demand. The extensive use of pesticides and their persistence in the aquatic and terrestrial environments may pose a detrimental impact on the ecosystem. The fate of pesticides in the ecosystem is determined by their structure, physicochemical properties and inherent biodegradability. In the recent decade, the presence of pesticides and their residues have been reported in the soil, surface water, groundwater and wastewater. Different methods and technologies have been reported to remediate the pesticide-contaminated environment, which include physical, chemical, biological/microbial and enzymatic processes. Among these, microbial remediation is found to be an inexpensive, environmentally friendly and thermodynamically more affordable technology that can be applied to any material soiled by a pesticide. The major groups of microorganisms, viz., bacteria, fungi and algae, have been successfully used to remediate different types of pesticides by various mechanisms of removal and transformation. These microorganisms can either accumulate and/or metabolize the pesticides and transform them into products that are less toxic or non-toxic as compared to the parent compounds. Nevertheless, more scientific investigations into the technical aspects of microbial bioremediation systems are needed, as they persist for many years in nature and travel to various food chains. This chapter focuses on the current status of pesticide pollution and the role of microbe-assisted remediation of pesticides. Different aspects of microbe-mediated remediation of pesticides such as types, mechanisms and future perspectives have been discussed. � 2024 Anju Malik and Vinod Kumar Garg.Item Soil Microbiome: Diversity, Benefits and Interactions with Plants(Multidisciplinary Digital Publishing Institute (MDPI), 2023-10-09T00:00:00) Chauhan, Poonam; Sharma, Neha; Tapwal, Ashwani; Kumar, Ajay; Verma, Gaurav Swaroop; Meena, Mukesh; Seth, Chandra Shekhar; Swapnil, PrashantPlant roots aid the growth and functions of several kinds of microorganisms such as plant growth-promoting rhizobacteria, mycorrhizal fungi, endophytic bacteria, actinomycetes, nematodes, protozoans which may impart significant impacts on plant health and growth. Plant soil�microbe interaction is an intricate, continuous, and dynamic process that occurs in a distinct zone known as the rhizosphere. Plants interact with these soil microbes in a variety of ways, including competitive, exploitative, neutral, commensal, and symbiotic relationships. Both plant and soil types were found to have an impact on the community diversity and structure of the rhizosphere, or vice versa. The diversity of microorganisms in soil is thought to be essential for the management of soil health and quality because it has different plant growth-promoting or biocontrol effects that could be very advantageous for the host plant and alter plant physiology and nutrition. The composition of microbial community is influenced by soil and plant type. Besides these beneficial microbes, the soil also harbors microorganisms that are detrimental to plants, competing for nutrients and space, and causing diseases. Numerous microorganisms have antagonistic activity and the ability to defend plants from soil-borne diseases. The study of the soil microbiome is essential for formulating strategies for transforming the rhizosphere to the benefit of the plants. This review pays special emphasis on the types of microbial populations in the soil and how they influence plant growth, nutrient acquisition, inter-relationships between soil microbes and plants, stress resistance, carbon sequestration, and phytoremediation. � 2023 by the authors.Item Genome-wide identification and gene expression analysis of GHMP kinase gene family in banana cv. Rasthali(Springer Science and Business Media B.V., 2023-09-20T00:00:00) Chaturvedi, Siddhant; Khan, Shahirina; Thakur, Neha; Jangra, Alka; Tiwari, SiddharthBackground: The GHMP kinase gene family encompasses ATP-dependent kinases, significantly involved in the biosynthesis of isoprenes, amino acids, and metabolism of carbohydrates. Banana is a staple tropical crop that is globally consumed but known for high sensitivity to salt, cold, and drought stresses. The GHMP kinases are known to play a significant role during abiotic stresses in plants. The present study emphasizes the role of GHMP kinases in various abiotic stress conditions in banana. Methods and results: We identified 12 GHMP kinase (MaGHMP kinase) genes in the banana genome database and witnessed the presence of the conserved Pro-X-X-X-Gly-Leu-X-Ser-Ser-Ala domain in their protein sequences. All genes were found to be involved in ATP-binding and carried kinase activity confronting their biological roles in the isoprene (27%) and amino acid (20%) biosyntheses. The expression analysis of genes during cold, drought, and salt stress conditions in tissue culture grown banana cultivar Rasthali plants showed a significant involvement of MaGHMP kinase genes in these stress conditions. The highest expression of MaGHMP kinase3 (8.5 fold) was noted during cold stress, while MaGHMP kinase1 (25 fold and 40.01 fold) showed maximum expression during drought and salt stress conditions in leaf tissue of Rasthali. Conclusion: Our findings suggested that MaGHMP kinase1 (MaHSK) and MaGHMP kinase3 (MaGlcAK) could be considered promising candidates for thwarting the abiotic stresses in banana. � 2023, The Author(s), under exclusive licence to Springer Nature B.V.Item Nanotechnology as a powerful tool in plant sciences: Recent developments, challenges and perspectives(Elsevier B.V., 2023-08-24T00:00:00) Kumari, Avnesh; Rana, Varnika; Yadav, Sudesh Kumar; Kumar, VinayIn today's global climate emergency, agricultural practices are becoming increasingly unsustainable. There are a number of alarming issues that require immediate action, including soil erosion, excessive use of natural resources, biodiversity loss, and an explosion of population. Although agriculture is heavily modernized, with traditional approaches, it is not possible to meet these challenges due to different landscapes, high nutrition demand, and a lack of technology. Aside from adversely affecting agriculture, chemical use has also resulted in serious health issues and undesirable effects on the ecosystem. As a result, nanotechnology will play a significant role in delivering a well-organized, sustainable agricultural industry by reducing chemicals and addressing existing problems. A quick disease diagnosis, improved plant nutrient absorption, and increased plant capability to absorb nutrients can be achieved by nanotechnology in the food and agriculture industries. Agricultural plants can be protected from insects and pests by nanotechnology acting as sensors to monitor soil and water quality. Despite their potential, researchers have been unable to understand how these compounds operate, since NPs either enhance growth or cause cytotoxicity depending on how much concentration is applied. In this article, we present the most promising nanoparticles used in abiotic stress management and gene editing of plants, as well as novel nanobionic approaches for improving plant functions and organelles. � 2023 The AuthorsItem Gene delivery methods: Advances and opportunities of nanoparticles-based techniques(CRC Press, 2023-09-06T00:00:00) Borgohain, Venus; Swati, Z.Z.Z.; Reetu, Z.Z.Z.; Kumar, VinayItem Exogenous application of biostimulants for As stress tolerance in crop plants(Elsevier, 2023-08-04T00:00:00) Garg, Tashima; Arora, Bhumika; Bokolia, Muskan; Joshi, Anjali; Kumar, Vinay; Kumar, Avneesh; Kaur, SimranjeetArsenic (As) is a nonessential toxic metalloid existing in two different inorganic forms: arsenite As (III) and arsenate As (V) which cause hindrance in plant developmental processes and are hazardous to human beings. As contamination is a major environmental issue as it stimulates physiological and metabolic dysfunctions, for instance, nutrient and redox imbalance, rate of photosynthesis, and membrane integrity, ultimately leading to reduced crop yield. Plants show detoxification processes to overcome As toxic effects by effluxing excess metal ions through metal transporters, accumulating As in the vacuole, and producing antioxidant enzymes. In recent times, the exogenous application of various biostimulants such as hormones, antioxidants, osmolytes, and others is being explored to combat As-mediating injuries to crop plants. These compounds are effective in improving seed germination, antioxidant enzyme activity, plant biomass, and overall growth of the plants. The objective of this chapter is to provide recent knowledge on the biostimulants hallmarks to alleviate As stress in crop plants. � 2023 Elsevier Inc.

Abscisic acid (ABA) is a key stress regulator, and its responsive genes are controlled by ABRE (Abscisic acid Responsive Element)-binding factors (ABFs)and G-Box Regulatory factors (GRFs). Here, we identify ABFs, GRFs and targeting miRNAs in desi and kabuli chickpea. To validate their role after drought priming and subsequent high temperature stress, two contrasting chickpea varieties (PBG1 and PBG5) were primed and exposed to 32 �C, 35 �C and 38 �C for 12, 6 and 2 h respectively and analyzed for Physio-biochemical, expression of ABFs, GRFs and MiRNAs, and GC-MS based metabolite analysis. To ascertain the ABF-GRF protein-protein interactions, docking studies were carried out between the ABF3 and GRF14. Genome-wide analysis identified total 9 & 11 ABFs, and 11 GRFsin desi and kabuli respectively. Their gene structure, and motif composition were conserved in all subfamilies and only 10 and 12 genes have undergone duplication in both desi and kabuli chickpea respectively. These genes were differentially expressed in-silico. MiR172 and miR396 were identified to target ABFs and GRFs respectively. Protein-protein interaction (ABF3 and GRF14) might be successful only when the ABF3 was phosphorylated. Drought priming downregulated miR172 and miR396 and eventually upregulated targeting ABFs, and GRFs. Metabolite profiling (GC-MS) revealed the accumulation of 87 metabolites in Primed (P) and Non-Primed (NP) Chickpea plants. Tolerant cultivar (PBG5) responded better in all respects however both severity of stress and exposure are important factors and can produce broadly similar cellular response. � 2023 Elsevier Masson SASItem Biotechnological attributes of biostimulants for relieving metal toxicity(Elsevier, 2023-08-04T00:00:00) Rana, Varnika; Kumar, Adarsh; Singh, Reetu; Kumar, VinayA global scourge, heavy metals (HMs) toxicity with high concentration causes reactive oxygen species (ROS) to attack key biological molecules and has emerged in the past few years, posing a serious threat to human lives and ecosystems and agriculture. In plants, HMs alter the genome and genetic structure and eventually affect their protein and enzyme activities which further impede cellular metabolism. Therefore the growing body of scientific research is emphasizing green synthesis, that is, biostimulants use as the nexus of biotechnology and fertilizer that can be viewed as novel, efficient, eco-friendly, and cost-effective tools to safeguard the detrimental effects on ecosystems. In this regard, this chapter aims to scrutinize the role of various biostimulants against abiotic stresses using various biostimulants including seaweed extracts, protein hydrolysates, humic acids, and fulvic acids. The microbial-based stimulants are also discussed in this chapter. A list of biological processes has also been highlighted as prime targets for removing heavy metal(loid)s toxicity using biotechnological interventions. The biostimulants enhance growth and improve stress tolerance ability in plants. A table of targeted biotechnological attributes is also provided. Recently, a steep rise in interest in biostimulants is driving the development of sustainable green economics and agricultural concepts, while increasing demand for new products and understanding their mechanism of action is increasing. Further, the increasing demand for innovative biostimulants products and an interest in understanding their mechanisms of action will drive HM-free green economics and agricultural sustainability in the coming days. � 2023 Elsevier Inc.
