Plant biomass (a), root biomass (b), and root length (c) in Medicago truncatula genotypes. T: plants nitrogen-fertilized control, TII7: inoculated with TII7, and SII4: inoculated with SII4, growing in the presence of Fe (C), in the direct iron deficiency (DD), and in the induced iron deficiency (ID) during the treatment period (21 days). Values are the means of eight replicates ± SD at P<5%. Graphs denoted with different small letters are significantly different according to the Tukey test.
