)(Fig. 2). Fe deficiency (ID) and Fe-deficiency anaemia are the most common nutritional disorders in humans throughout the world (Paesano et al.,
2010). It is also reported that Fe deficiency has a negative impact
on brain functioning in infants (Milman, 2011). Fe biofortification
of major staple food plants like taro is therefore one of the crucial
issues. Unfortunately, there are still many uncertainties about the
physiological processes involved in Fe uptake and loading in different parts of corms.
