    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, Deepak
    Being 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.

    Insight of oral vaccines as an alternative approach to health and disease management: An innovative intuition and challenges
    (John Wiley and Sons Inc, 2022) Debnath, Nabendu; Thakur, Mony; Khushboo; Negi, Neelam P.; Gautam, Vibhav; Kumar Yadav, Ashok; Kumar, Deepak
    Vaccination is the most suitable and persuasive healthcare program for the prohibition of various deadly diseases. However, the higher production cost and purification strategies are out of reach for the developing nations. In this scenario, development of edible vaccine turns out to be the most promising alternative for remodeling the pharmaceutical industry with reduced production and purification costs. Generally, oral route of vaccination is mostly preferred due to its safety, compliance, low manufacturing cost and most importantly the ability to induce immunity in both systemic and mucosal sites. Genetically modified microorganisms and plants could efficiently be used as vehicles for edible vaccines. Edible vaccines are supposed to reduce the risk associated with traditional vaccines. Currently, oral vaccines are available in the market for several viral and bacterial diseases like cholera, hepatitis B, malaria, rabies etc. Herein, the review focuses on the breakthrough events in the area of edible vaccines associated with dietary microbes and plants for better control over diseases. � 2021 Wiley Periodicals LLC

    Unlocking the Secrets of Rhizosphere Microbes: A New Dimension for Agriculture
    (Springer Science and Business Media B.V., 2024) Thakur M.; Khushboo; Shah S.; Kumari P.; Kumar M.; Vibhuti R.K.; Pramanik A.; Yadav V.; Raina M.; Negi N.P.; Gautam V.; Rustagi A.; Verma S.K.; Kumar D.
    Rhizospheric microbes help plants to acquire and assimilate nutrients, improve soil texture and modulate extracellular molecules. Rhizosphere bacteria regularly encounter a copious number of variables, such as temperature, pH, nutrients, pest resistance mechanisms, etc. The extracellular concentration of chemical messengers fabricated by plant growth promoting bacteria (PGPB) in a system is directly proportional to the bacterial population. To dwindle the use of chemically synthesised pesticides, plant growth-promoting rhizobacteria (PGPR) are new arsenals of imperishable agricultural practises for managing plant pathogens and resistance. This review aims to harness the rhizosphere milieu to raise climate smart crops. The PGPB mediated hormonal control of plant stress management pathway could be potentially modified for the benefit of plants. Nutrient solubilisation strengthens the rhizomicrobiome for phytoremediation and pathogen control. Quorum sensing as well as the role of enzymes and siderophores in rhizo-microbiome has been discussed. With advent of metagenomics, the understanding of soil microbiome ecology has acquired new dimensions and has enabled us to modify the microbiome for sustainable agriculture and enhanced productivity. � The Author(s), under exclusive licence to Springer Nature B.V. 2024.
