CADMIUM ACCUMULATION  AND TOLERANCE IN PLANTS
 
      Since plants generally have no choice where they germinate and grow, they must adapt to unfavorable environmental conditions to survive. In order to tolerate Cd-rich soils, plants have four general strategies: 1) metal is bound to the cell wall, 2) reduced transport across cell membrane, 3) compartmentalization , 4) chelation (Prasad, 1995). Most plants utilize one or more of these strategies to avoid Cd toxicity.
