Figure 3.
Iron excess in rosette leaves of the Atfer134 triple mutant. Sections of 4-week old Atfer134 plants irrigated with either water (A,C) or Fe-EDDHA 2 mM during 48 h (B,D) were stained with either Perls/DAB (A,B,D) or DAB alone as a negative control. (C) Fe accumulation in the extracellular space is indicated by arrowheads in panel (D). Scale bars: 50 μm (A,B) or 20 μm (C,D).
