The wri1-1 mutation causes a reduction in germination and establishment

Line 101 and line 106 express the WRI1 cDNA under the control of the 35S-CaMV promoter. Percentages of germinated seeds of all seeds plated, and establishment defined as percentage of plants of all seeds plated growing beyond radicle emergence are shown. The sd of the mean from three trials is given. Suc was added (+) at 50 mm, giberellic acid (GA) at 5 μm.
