Iron contents in shoot biomass harvested at senescent stage from extracellular ferritin-overexpressing (FerEX) transgenic Arabidopsis plants. The plants were H2O-watered (a) or irrigated with 2 mM Fe-EDDHA (b) twice a week during plant growth. Data are presented as the mean (±SE) of five replicates. ** indicates statistical significance of p < 0.01 from the empty vector (EV) controls. FerEX(1) and (2) represent FerEX-8a and -10g, respectively
