Metal tolerance is an important aspect for optimal production of edible plants for horticulture, cereals, spices, and medicinal and aromatic plants. Extravagant use of chemicals, fertilizers, and pesticides in agriculture along with contamination of irrigation water has made the soil and water resources unusable or highly contaminated with heavy metals. This chapter provides information in a nutshell on status and sources of metal contamination, role of metals in physiological and biological success of plants, and mechanistic part of metal toxicity (how metals inhibit different physiological processes in different plants) and further explains different mechanism prevailing to metal tolerance among different plant groups. Later a little information on molecular aspects of plants tolerance has also been highlighted. At current scenario, this information will be highly important to understand the specific role and significance of some metals in plant physiological processes and different mechanisms of removal of toxic metals as exclusion, avoidance, and tolerance for selecting or engineering specific metal toxicity-tolerant edible plant.
