Interpretive Summary: Common bean is an important crop plant and source of human health related macro- and micronutrients. Common bean uptake these nutrients from the soil environment and transport them to various storage tissues using proteins and genes located in different tissues (Phan-Thein et al. 2010). However, along with essential elements plants also uptake and translocate toxic metals from soil environment. At leaf senescence period, minerals from other parts remobilize and accumulate into seed (Rossato et al. 2001). The uptake and translocation of these elements depends on the chemical properties of the elements, their binding specificities with the ligands as well as tissue types (Ghandilyan et al. 2009). Our objectives in this study were to understand the influence of elevated Fe, Zn, and Cd on different mineral elements concentration and translocation through tissues of common bean.
