Time course of expression of metal homeostasis-related genes in Kas-1 and Tsu-1 ecotypes. (A) OPT3, (B) FRO3, (C) NRAMP4, (D) COPT2 in rosettes, and (E) COPT2 in roots. n=3 ±SD. *Denotes statistical significance for Kas-1, + denotes statistical significance for Tsu-1 (P < 0.05) between treatments at each time point. +Fe, 50 µM Fe; –Fe, no added Fe.
