Functional redundancy of YUC family genes in RCN. (A) Increases in LR number under different concentration of yucasin in the presence of NPA. Increases in the LR number were calculated by subtracting the LR number of intact plants from those of root-cut plants. (B) Four-day-old plants were transferred to medium with or without NPA and incubated for 1 d before root cutting. Photographs were taken 4 d after root cutting. Scale bars = 1 cm. Red arrowheads indicate the 12 mm point from the root–shoot junction that corresponds to the cut point. LR number of plants after root cutting in the absence (C) or presence (D) of NPA. LR number was counted within 12 mm from the root–shoot junction 4 d after root cutting. Scale bars = 1 cm. Error bars indicate the SE (n = 16). *Significant differences compared with the WT (Student’s t-test, P < 0.01).
