Arabidopsis MIT1 and MIT2 complement the defective growth phenotype of mrs3mrs4 on Fe-deficient media. mrs3mrs4 was transformed with MIT1, MIT2, MRS3 (positive control) and the empty vector (pRS426-ADH; negative control). Three serial dilutions corresponding to OD600 of 1, 0.1 and 0.01 of the transformed yeast were assayed for growth complementation on SD-uracil plates under Fe-sufficient (0.1mM FeSO4) or Fe-deficient (0.1mM BPS) conditions.
