Fig. 2From: Early transcriptomic response to Fe supply in Fe-deficient tomato plants is strongly influenced by the nature of the chelating agentFe(III)-reduction activity of tomato roots. Fe(III)-reduction activity of intact Fe-deficient tomato plants supplied for 1 h with 1 μM Fe as Fe-citrate, Fe-PS or Fe-WEHS; as control, Fe-deficient plants not treated with any Fe sources (-Fe) or plants treated with 100 μM Fe (+Fe), were also utilized. Data are means ± SD of three independent experiments. Capital letters (a to b) refer to statistically significant differences (Holm–Sidak method ANOVA, P < 0.05)Back to article page
