Expression of PsMT1 (A) and PsMT2 (B) genes in the nodules of pea (Pisum sativum) plants grown hydroponically without cadmium stress (control) and with the addition of 0.5 μM CdCl2. Letters indicate significant differences (two-way ANOVA, p ≤ 0.05): a, from the control; b, of the control SGECdt from control wild-type plants inoculated with the same strain of Rhizobium leguminosarum bv. viciae; c, of treated SGECdt from the treated wild type inoculated with the same strain of R. leguminosarum bv. viciae.
