Effect of Exogenous GA₃ Application on LR Development of 35S:PcGA2ox1 Transgenic and Wild-Type Plants.

(A) Effect of GA₃ application on aerial and root development in 35S:PcGA2ox1 transgenic and wild-type plants. Photographs were taken 6 d after GA₃ application. Top and bottom panels show aerial and root development, respectively, of plants in the same Magenta box.

(B) to (D) Quantitative analysis of LR density (B), LR length (C), and primary root (PR) length (D) at 12 d after GA₃ treatment. Bars represent means and se of two independent experiments where each experiment included at least six ramets per event. ** and * indicate significance at P < 0.01 and P < 0.05, respectively.
