摘要: Heavy metals have been consistent source of environmental pollution. Among all the heavy metals, arsenic (As), a non-essential element for plants, is one major pollutants affecting human life. Arsenic exists in three forms, arsenate (AsV), arsenite (ASIII) and as methylated species. These forms are taken up by different mechanism mobilized inside plants. The causes toxicity mainly due to interference ATP synthesis alteration protein structure catalytic properties. Plants detoxify largely complexation with phytochelatins and/or vacuolar sequestration. Existence genetic variation germplasm crop cultivars respect accumulation offers hope classical breeding strategies develop arsenic-tolerant cultivars. In this chapter, along how being metabolized we also discuss ways detoxification metal pollutant.
