Calcium Biofortication of Crops

More than half of the world’s population is decient in calcium (Ca), iron (Fe), iodine (I), magnesium (Mg), selenium (Se), or zinc (Zn) (Graham et al. 2007; White and Broadley 2009). The consumption of plants, directly or via livestock, containing inadequate concentrations of particular minerals causes these deciencies. Agronomic and genetic strategies can increase the delivery of bioavailable minerals (Figure 17.1) (Morris et al. 2008; White and Broadley 2009). Although the focus is predominately on Ca, the framework discussed here should be generally applicable to boosting the levels of other elements in agriculturally important crops.
