    Nanotechnology: An Efficient Tool in Plant Nutrition Management
    (Nova Science Publishers, Inc., 2022) Sharma, Sachin; Singh, Surendra; Bahuguna, Ayush; Yadav, Bharti; Barthwal, Akshita; Khatana, Raghu Nandan Singh; Pandey, Astha; Thakur, Rajneesh; Jatav, Hanuman Singh
    The increasing global population accelerates world food demand with limited land resources. It shifts the research towards higher productivity with higher fertilizer use on large scale but with high economic inputs. This promotes the use of Nanotechnology in fertilizer industries which offers higher production with the desired customization in nutrient values, high reactivity, changeable surface area, high nutrient use efficiency because of its different physic-chemical properties. Nanoparticles facilitate a smart delivery system of nutrients with the targeted cellular approach in plants as well as in the rhizosphere. The nanopolymers and nano fertilizers also benefit the plant in stress resistance, crop nutrient quality and improve water use efficiency. However, the behavior of nanoparticles to surpass the food chain, its concentration and toxicity in edible products is still a topic of research. The present chapter deals with their mechanisms, controlled release pattern, particle morphology, chemical kinetics, interaction with soil colloids as well as the effect on the microbiome with lesser amount application in the field and proves to replace the current conventional fertilizers with sustainability and minimal environmental risks. � 2022 by Nova Science Publishers, Inc.

    Role of plant secondary metabolites in defence and transcriptional regulation in response to biotic stress
    (Elsevier B.V., 2023) Anjali; Kumar, Sumit; Korra, Tulasi; Thakur, Rajneesh; Arutselvan, R.; Kashyap, Abhijeet Shankar; Nehela, Yasser; Chaplygin, Victor; Minkina, Tatiana; Keswani, Chetan
    Secondary metabolites in plants have been recognized as a novel basis of potential bio-pesticides, paving the way for their use in sustainable agriculture. Plant secondary metabolites have pivotal roles in plant-pathogen interactions. Some important secondary metabolites of plants are terpenoids, flavanols, flavones, etc., are stress-inducible phytochemicals playing an important role in plant immune response development. Pathogen enters into host cell, multiply and utilise the biological mechanism of plants, causing a hazard to world food assembly. Under stressed circumstances, plants evolve a powerful and intricate system of growth and defensive action. On the other hand, transcription factors (TFs) assist host plants to counter adverse environments by acting as mediators of stress signal and regulating the stress-responsive gene expression. The transcriptional and post-transcriptional manipulation of transcriptional factors is capable of aid in molecular breeding and genetic modification meant for improved secondary metabolite synthesis. Although the presence of numerous secondary metabolites has been established in plant life, very slight is known about their interaction with pathogens and the specific mechanisms involved in leading to plant immunity. Chemical pesticides are wreaking havoc on our environment. As a consequence, environmental-friendly alternatives to disease management, like plant-based metabolites, should be explored. In this appraisal, we have reviewed plant secondary metabolites in relation to pathogens, their contribution to innate immunity, mechanism of action, and regulation of TFs in response to combating plant infections in an eco-friendly approach. � 2023 The Authors
