Figure 5From: Comparative transcriptomic characterization of aluminum, sodium chloride, cadmium and copper rhizotoxicities in Arabidopsis thalianaHistochemical analyses of roots of Arabidopsis thaliana after incubation in rhizotoxic solutions. Growing roots were immersed in rhizotoxic solutions containing AlCl3 (25 μM), NaCl (50 mM), CdCl2 (15 μM) or CuSO4 (1.6 μM) for 24 h, stained with 2',7'-dichlorodihydrofluorescein diacetate (H2DCFDA) or dihydroethidium (DHE), and then observed under a fluorescence microscope. Fluorescent and bright field images are shown. Images of non-stressed roots are shown as controls. White bar indicates 100 μm.Back to article page
