In this article, the impact of an anthropogenically transformed environment on the content of pharmaceutically valuable biologically active compounds in medicinal plants is analyzed. The studied biologically active substances included phenolic compounds (flavonoids, anthocyanins, tannins, and phenolic acids). The number of transmissible forms of heavy metals (HMs), including cadmium, lead, and mercury, were discharged from factories that are present in the soil. Plants uptake these toxic metals from the soil. HM causes changes in the activity of the several enzymes such as phenylalanine ammonia lyase (PAL), chalcone synthase (CHS), chalcone isomerase (CHI) and other enzymes. These enzymes play an important role in biosynthesis of phenolic compounds in medicinal plants. It has been demonstrated that plant materials possess high antioxidant potential due to their high phenolic content. As a result, the present review discusses a thorough investigation of anthropogenically transformed environment effects on the quantity of pharmaceutically valuable phenolic compounds in medicinal plants. © 2023 by the authors.

Biochar is considered as a potential substitute for soil organic matter (SOM). Considering the importance of biochar, the present review is based on the different benefits and potential risks of the application of biochar to the soil. Biochar addition to low organic carbon soils can act as a feasible solution to keep soil biologically active for the cycling of different nutrients. The application of biochar could improve soil fertility, increase crop yield, enhance plant growth and microbial abundance, and immobilize different contaminants in the soil. It could also be helpful in carbon sequestration and the return of carbon stock back to the soil in partially combusted form. Due to the large surface area of biochar, which generally depends upon the types of feedstock and pyrolysis conditions, it helps to reduce the leaching of fertilizers from the soil and supplies additional nutrients to growing crops. However, biochar may have some adverse effects due to emissions during the pyrolysis process, but it exerts a positive priming effect (a phenomenon in which subjection to one stimulus positively influences subsequent stimulus) on SOM decomposition, depletion of nutrients (macro-and micro-) via strong adsorption, and impact on soil physicochemical properties. In view of the above importance and limitations, all possible issues related to biochar application should be considered. The review presents extensive detailed information on the sustainable approach for the environmental use of biochar and its limitations. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.

From germination to maturity, crops face myriad stresses thereby threatening food security. The foundation of modern agriculture rests on the status of seed health and resilience. Hence, developing highly efficient, low-cost, farmer-friendly, and sustainable approaches for improving seed health and performance under both field and greenhouse conditions. Seed bio-priming with plant beneficial microorganisms (++; mutualistic) improves the physiological, molecular, and stress tolerance functions of the seeds. This process allows the microorganisms adhere to the seed coat and establish an early relationship with the radicle, thereby forming the first line of defense against any external threat. Seeds bio-primed by mutualistic rhizomicroorganisms stimulate plant immunity by inducing the biosynthesis of defense-related proteins, phytohormones, antioxidants, polyphenols, etc. This review maps the various functional and applied aspects of seed bio-priming on the overall plant health under stressed environments. Furthermore, it critically examines the modulation of biochemical and molecular mechanisms for establishing redox homeostasis. © The Author(s), under exclusive licence to Springer Science+Business Media, LLC, part of Springer Nature 2024.
