Tolerance of ZmCCD10a-overexpressing Arabidopsis plants to LP. A, ZmCCD10a-overexpressing (nos. 15, 18, 24) and wild-type (Col-0) plants under sufficient (Ctrl) and LP. B, Relative expression of ZmCCD10a in three overexpression lines. C to E, Root (C) and shoot (D) biomass, and the root-shoot ratio (E) of ZmCCD10a-overexpressing lines under control (Ctrl) and LP conditions. F, Anthocyanin accumulation in ZmCCD10a-overexpressing leaves. P concentrations (conc.) in roots (G) and shoots (H) of ZmCCD10a-overexpressing lines compared with wild-type plants. Relative expression of P starvation-induced genes AtPHT1;1 (I), AtPHT1;5 (J), AtPHR1 (K), AtPHO1 (L), and AtPHO2 (M) in ZmCCD10a-overexpressing lines in comparison to wild-type plants. Error bars represent the se of four biological replicates. Asterisks indicate significant difference as determined by one-way ANOVA (**P < 0.01). DW, Dry weight.
