Greenhouse experiment for evaluation of nitrogen use efficiency in transgenic events and wild type. a Root dry weight of three transgenic events and wild type at 3 N doses. b Shoot dry weight of three transgenic events and wild type at 3 N doses. c Tiller number of three transgenic events and wild type at 3 N doses. d Grain yield of three transgenic events and wild type at 3 N doses. Bars represent the means ± s.d. of three replicates. Means labeled with * indicate significant differences from WT at the corresponding N dose at P < 0.05
