- Durrett T, Connolly E, Rogers E. Arabidopsis cpFtsY mutants exhibit pleiotropic defects including an inability to increase iron deficiency-inducible root Fe(III) chelate reductase activity. Plant J. 2006;47:467-79 pubmed..In Arabidopsis, the enzyme responsible for this reductase activity in the roots is encoded by FRO2. Two Arabidopsis mutants, frd4-1 and frd4-2, were isolated in a screen for plants that do not induce Fe(III) ..
