Food safety has emerged as a high-urgency matter for sustainable agricultural production. Toxic metal contamination of soil and water significantly affects productivity, which is further aggravated by extreme anthropogenic activities modern practices, leaving food human health at risk. In addition to reducing crop production, increased metals/metalloids toxicity also disturbs plants' demand supply equilibrium. Counterbalancing toxic demands better understanding the complex mechanisms physiological, biochemical, molecular, cellular, plant level that may result in productivity. Consequently, plants have established different internal defense cope with adverse effects metals/metalloids. Nevertheless, these are not adequate overwhelm toxicity.
