Item Fostering plant growth performance under drought stress using rhizospheric microbes, their gene editing, and biochar(Springer, 2024) Chauhan P.K.; Upadhyay S.K.; Rajput V.D.; Dwivedi P.; Minkina T.; Wong M.H.Stress due to drought lowers crop yield and frequently leads to a rise in food scarcity. Plants' intricate metabolic systems enable them to tolerate drought stress, but they are unable to handle it well. Adding some external, environmentally friendly supplements can boost plant growth and productivity when it comes to drought-stressed plants. In order to prevent the detrimental effects of drought in agricultural regions, environmentally friendly practices must be upheld. Plant growth-promoting rhizobacteria (PGPR) can exhibit beneficial phytostimulation, mineralization, and biocontrol activities under drought stress. The significant impact of the PGPR previously reported has not been accepted as an effective treatment to lessen drought stress. Recent studies have successfully shown that manipulating microbes can be a better option to reduce the severity of drought in plants. In this review, we demonstrate how modifying agents such as biochar, PGPR consortia, PGPR, and mycorrhizal fungi can help overcome drought stress responses in crop plants. This article also discusses CRISPR/Cas9-modifiable genes, increase plant�s effectiveness in drought conditions, and increase plant resistance to drought stress. With an eco-friendly approach in mind, there is a need for practical management techniques having potential prospects based on an integrated strategy mediated by CRISPR-Cas9 editing, PGPR, which may alleviate the effects of drought stress in crops and aid in achieving the United Nation Sustainable Development Goals (UN-SDGs-2030). � 2023, The Author(s), under exclusive licence to Springer Nature B.V.Item Nano-assisted delivery tools for plant genetic engineering: a review on recent developments(Springer, 2024) Kumar P.; Rajput V.D.; Singh A.K.; Agrawal S.; Das R.; Minkina T.; Shukla P.K.; Wong M.H.; Kaushik A.; Albukhaty S.; Tiwari K.N.; Mishra S.K.Conventional approaches like Agrobacterium-mediated transformation, viral transduction, biolistic particle bombardment, and polyethylene glycol (PEG)-facilitated delivery methods have been optimized for transporting specific genes to various plant cells. These conventional approaches in genetically modified crops are dependent on several factors like plant types, cell types, and genotype requirements, as well as numerous disadvantages such as time-consuming, untargeted distribution of genes, and high cost of cultivation. Therefore, it is suggested to develop novel techniques for the transportation of genes in crop plants using tailored nanoparticles (NPs) of manipulative and controlled high-performance features synthesized using green and chemical routes. It is observed that site-specific delivery of genes exhibits high efficacy in species-independent circumstances which leads to an increased level of productivity. Therefore, to achieve these outcomes, NPs can be utilized as gene nano-carriers for excellent delivery inside crops (i.e., cotton, tobacco, rice, wheat, okra, and maize) for desired genetic engineering modifications. As outcomes, this review provides an outline of the conventional techniques and current application of numerous nano-enabled gene delivery needed for crop gene manipulation, the benefits, and drawbacks associated with state-of-the-art techniques, which serve as a roadmap for the possible applicability of nanomaterials in plant genomic engineering as well as crop improvement in the future. � The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.Item Nanomaterials and biochar mediated remediation of emerging contaminants(Elsevier B.V., 2024) Rajput P.; Kumar P.; Priya A.K.; Kumari S.; Shiade S.R.G.; Rajput V.D.; Fathi A.; Pradhan A.; Sarfraz R.; Sushkova S.; Mandzhieva S.; Minkina T.; Soldatov A.; Wong M.H.; Rensing C.The unrestricted release of various toxic substances into the environment is a critical global issue, gaining increased attention in modern society. Many of these substances are pristine to various environmental compartments known as contaminants/emerging contaminants (ECs). Nanoparticles and emerging sorbents enhanced remediation is a compelling methodology exhibiting great potential in addressing EC-related issues and facilitating their elimination from the environment, particularly those compounds that demonstrate eco-toxicity and pose considerable challenges in terms of removal. It provides a novel technique enabling the secure and sustainable removal of various ECs, including persistent organic compounds, microplastics, phthalate, etc. This extensive review presents a critical perspective on the current advancements and potential outcomes of nano-enhanced remediation techniques such as photocatalysis, nano-sensing, nano-enhanced sorbents, bio/phyto-remediation, which are applied to clean-up the natural environment. In addition, when dealing with residual contaminants, special attention is paid to both health and environmental implications; therefore, an evaluation of the long-term sustainability of nano-enhanced remediation methods has been considered. The integrated mechanical approaches were thoroughly discussed and presented in graphical forms. Thus, the critical evaluation of the integrated use of most emerging remediation technologies will open a new dimension in environmental safety and clean-up program. � 2024 Elsevier B.V.Item The efficient applications of native flora for phytorestoration of mine tailings: a pan-global survey(Springer, 2024) Swain A.A.; Sharma P.; Keswani C.; Minkina T.; Tukkaraja P.; Gadhamshetty V.; Kumar S.; Bauddh K.; Kumar N.; Shukla S.K.; Kumar M.; Dubey R.S.; Wong M.H.Mine tailings are the discarded materials resulting from mining processes after minerals have been extracted. They consist of leftover mineral fragments, excavated land masses, and disrupted ecosystems. The uncontrolled handling or discharge of tailings from abandoned mine lands (AMLs) poses a threat to the surrounding environment. Numerous untreated mine tailings have been abandoned globally, necessitating immediate reclamation and restoration efforts. The limited feasibility of conventional reclamation methods, such as cost and acceptability, presents challenges in reclaiming tailings around AMLs. This study focuses on phytorestoration as a sustainable method for treating mine tailings. Phytorestoration utilizes existing native plants on the mine sites while applying advanced principles of environmental biotechnology. These approaches can remediate toxic elements and simultaneously improve soil quality. The current study provides a global overview of phytorestoration methods, emphasizing the specifics of mine tailings and the research on native plant species to enhance restoration ecosystem services. � The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature 2024.Item Transforming bio-waste into value-added products mediated microbes for enhancing soil health and crop production: Perspective views on circular economy(Elsevier B.V., 2024) Upadhyay S.K.; Singh G.; Rani N.; Rajput V.D.; Seth C.S.; Dwivedi P.; Minkina T.; Wong M.H.; Show P.L.; Khoo K.S.Unprecedented increasing of human population has led to the huge production of bio-wastes which is a rich source of plant nutrients. These bio-wastes consist of fundamental nutrients (e.g. phosphorous, nitrogen, and potassium) which can play a crucial role in protecting agriculture sectors from the adverse effects derived from synthetic fertilizers. Reusing bio-waste materials originating from agricultural waste, animal waste, and sewage sludge can aid in the recovery of nutrients as well as the development of products with value, in order fostering a circular economy. Waste valorization is the process of converting waste into valuable products for the enhancement of soil fertility and sustaining agricultural plant growth. Microbes and biological systems offer sustainable bioconversion mechanisms to convert bio-waste into valuable bio-products. By utilizing bio-based fertilizers derived from bio-waste, agricultural production can be increased while mitigating the negative environmental impact caused by synthetic fertilizers. These microbes are sourced from nature and cultivated in the laboratories which are further incorporated into suitable carrier materials for application in the soil. More research is needed to explore their field-level applications of bio-based fertilizers, which are supported based on 155 publications included in this study, to maintain agricultural sustainability and productivity. However, the interplay between plant and microbes must be carefully considered to ensure an optimal result in the field, sometimes requiring artificial augmentation. Therefore, the present review emphasizes the development of bio-based fertilizers through cutting-edge technology, microbial utilization, optimization for a circular economy, which opens new horizon for bio-waste minimization and its resource utilization. � 2024 The Authors
