Phenotype of Two New Alleles of FRD3.
(A) Position of frd3-6 and frd3-7 mutations on the FRD3 gene. LB, left border; G → A, guanine to adenine transversion.
(B) Phenotype of 7-week-old frd3-6 and frd3-7 mutants grown in soil. NM, nonmutagenized parental line; WT, wild type.
(C) frd3 chlorosis is reverted by iron supply. Four-week-old frd3-6 plants cultivated on soil were irrigated with water (−Fe) or 0.5 mM FeEDDHA (+Fe).
