Heavy metals contamination of plants
The effects of Cd on the subcellular localization in root tip cells of Hordeum vulgare were investigated by Energy dispersive x-ray analysis (EDXA) in order to further understand Cd toxic mechanisms in plants. EDXA showed that Cd ions were localized in meristem, elongation, and mature zone in the root tips. In transverse section of the mature zone, Cd was accumulated in epidermal, cortical, and vessel cells, and the level of Cd is in the order: epidermal cells < vessel cells < cortical cells. In cortical cells Cd ions were observed in cytoplasm and walls.
