Metabolome Modulation During Arsenic Stress in Plants

Abstract

Arsenic (As)-tainted agricultural land and drinking water is a global issue due to its extremely toxic and carcinogenic behavior for various life forms. Arsenic creates morphological disorder in plants by altering their physiology and metabolism. Recent solution culture and soil–plant system researches on As uptake and metabolism indicate that different forms of As exert toxicity in species-specific manner through inflection of diverse metabolites from crucial biological pathways. Various plant species adapt an array of genomic and proteomic approaches for As tolerance and detoxification which is manifested through stress-responsive metabolites. Eventually, the increased level of targeted metabolites during As stress plays a significant role for recovering the altered metabolism in plants. The review highlights the utility of modulated metabolites to understand their role for As tolerance and detoxification in As-stressed plants.
