Expression of genes involved in Fe uptake and translocation mechanisms. Expression of genes, as normalized counts, involved in Fe uptake and transport in both rootstocks and all tested treatments. Only nitrate as nitrogen source (N1A0); 1:1 ratio of nitrate and ammonium as nitrogen source (N1A1); Fe-sufficient treatment (+ Fe), Fe-deficient treatment (-Fe). Values represent the mean ± SE of three biological replicates (n = 3), Significant differences between treatments for each rootstock are indicated with different letters (α < 0.05, Welch ANOVA and Tukey or Games-Howell post hoc test, N = 3 per treatment and rootstock).
