Figure 3From: Iron and ferritin accumulate in separate cellular locations in Phaseolus seedsEffects of different growth conditions on seed iron distribution. Perls' Prussian blue (PPB) staining of seeds from five P. vulgaris genotypes grown in Darien, Colombia (Darien), or in a greenhouse in Denmark in 2008 (GH2008) or in 2009 (GH2009). The dry seeds were dissected and stained for 35 minutes using the PPB method. The genotypes names are shown. The scale bar is 1 cmBack to article page
