Plant system, abiotic stress resilience, reactive oxygen species, and coordination of engineered nanomaterials: A review

Nanotechnology has offered numerous growing opportunities in pharmaceutical, biomedical, cosmetics, textiles, electronics, automobiles, and agriculture. The broader implications on the commercial side are only recommended when a significant understanding of nano-triggered environmental toxicities is minimal or within acceptable limits. The agricultural outcomes are primarily based on the crop plant's performance in the growing areas. Therefore, productivity needed to be predicted by the plant responses under normal and stressed conditions. Here, the reactive oxygen species (ROS) level is a crucial and decisive factor for the overall performance of the desired genotype of particular crop plants. Since the entity is reactive and causing significant damage to the bio-machinery. Hence, regulation at the nano-dimension by the engineered nanomaterials (ENMs) is the most effective approach to mitigate the negative consequences. The preference for ENMs is strong because of having unique diversity in physical properties. Furthermore, the behavior of ROS is conditioned by hormonal concentration, secondary metabolites, and anti-oxidative systems. Therefore, a comprehensive study is needed to shed light on the ROS activity with the application of ENMs to direct research on the lesser exploited side. (c) 2024 SAAB. Published by Elsevier B.V.
