Fig. 1: Plant tillering and development.

a Ten-week-old WT and TG plants both initiating from a single tiller. Scale bar, 10 cm. b Representative leaves and internodes of WT and TG plants after initiation from single tillers. Scale bar, 2 cm. c Close up of the longest tillers from WT and TG plants. Scale bar, 5 cm. d All internodes from the representative longest tiller were sliced from top to bottom and arranged from left to right. Scale bar, 5 cm. e Three of the topmost fully developed leaves from the representative tillers of WT and TG plants. Scale bar, 2 cm. f Shoot and g root dry weight of WT and TG plants at 10 weeks after initiation from a single tiller (n = 4). h Tiller number in WT and TG plants at 5 and 10 weeks after initiation from a single tiller (n = 5). i Average length of the topmost eight internodes from WT and TG tillers (n = 6). j Leaf length and k leaf width from the representative WT and three transgenic lines (n = 3). Data are shown as means, and error bars represent standard error. A significant difference between WT and each TG line was indicated with asterisks (*, **, or ***) at P < 0.05, 0.01, or 0.001 by Student’s t-test
