Plants Under Metal and Metalloid Stress

In the industrial era, the most important potentialthreattocrop productionisabiotic stress, including toxic metal/metalloid stress. Growing populationsandrapid industrialization lead to the generation andreleaseof huge amountsof toxic metals/metalloids into the environment, altering plant physiological processes and reducing yields. In the last few decades, there has been extensive researchto elucidate the mechanisms of tolerance to metal/metalloid toxicity and waysto improve the defense system in plants. Use of exogenous photoprotectants such as osmoprotectants, plant nutrients, phytohormones, signaling molecules, antioxidants, amino acids and organic acids are widely being used to improve plants' tolerance to metal/metalloid stress.Recently, phytoremediation approaches have been effectively employed to remediate metal/metalloid pollution. Thisbookpresents the latestinsights intoplant responses and tolerance in plants grown under metal/metalloids stress to provide a better understandingofthe topic andthefuture outlook.
