Abstract
Cadmium (Cd) toxicity adversely affects
various developmental and physiological processes in plants, leading to
significant reductions in crop growth, biomass accumulation, and yield.
Exposure of excess Cd disrupts essential metabolic activities and induces the
overproduction of reactive oxygen species (ROS), affects various developmental
processes in plants. An increase in the production of reactive oxygen species
damages cellular components, including DNA, lipids, and proteins, owing to
their strong oxidizing properties. In response, plants activate both enzymatic
and non-enzymatic antioxidant defense systems to mitigate oxidative damage. A
comprehensive understanding of cadmium-induced toxicity is crucial for managing
heavy metal contamination in agricultural soils and promoting sustainable crop
production. Such knowledge also facilitates the development of targeted
mitigation strategies to enhance plant tolerance to heavy metal stress. Among
these approaches, nanotechnology has emerged as a promising tool. Nanoparticles
mitigated oxidative stress by reducing reactive oxygen species accumulation,
preserving cell membrane integrity, decreasing lipid peroxidation, electrolyte
leakage, and restricting heavy metal uptake and translocation within plants.
Overall, this review enhances our understanding of plant-metal interactions and
highlights the potential of nanoparticle-based interventions for improving crop
productivity, stress tolerance, and food safety in Cd-contaminated
environments.
