This problem arises when excessive amounts of essential or non-essential minerals accumulate in plants, disrupting physiological and biochemical processes. This stress is mainly caused by heavy metals (such as aluminum, cadmium, lead, arsenic) and essential mineral elements with higher concentrations (such as manganese, copper, zinc). Mineral toxicity stress causes increased oxidative stress in plant cells, which damages cellular membranes, affects the activation of enzymes, and decreases the rate of photosynthesis. This stress affects the primary and secondary metabolism in plants, thereby disturbing the nutrient balance. In this paper, a detailed study of the different types of mineral toxicity stress, its effects and the biological mechanisms of plant adaptability has been carried out. In addition, various adaptation mechanisms developed by plants to protect against mineral toxicity, such as Phytochelatin Synthesis, Antioxidant Defense Mechanism and Ion Transport Regulation have also been discussed. The aim of this research is to understand the response to mineral toxicity stress in plants and to develop effective strategies for its management. This research will not only contribute significantly to the field of plant sciences but will also be helpful towards sustainable agriculture and environmental sustainability.
Keywords- Mineral toxicity, Plant stress, Heavy metal pollution, Oxidative stress, Ion transport, Phytocellulation, Antioxidant defense system, Genetic adaptation, Sustainable agriculture.
