FEA1 facilitates iron uptake in Arabidopsis at high pH. Wild-type and transgenic Arabidopsis plants were grown hydroponically on 0.072 M Fe (Sprint 330) until day 48. (A) Image of wild-type (WT) and transgenic Arabidopsis plants grown at different pH levels (pH 5, 7, and 8.5). (B) Iron concentration of roots. (C) Iron concentrations of stems, leaves, and floral buds. Values are average of triplicates. Error bars represent SE. The asterisk (*) indicates statistically significant differences between wild-type and transgenics, determined by Student’s t-test, with P < 0.05.
