Fig. 1.

3KO plants generate more lateral (LR) and adventitious (AR) roots than Columbia or 3KOR plants. Seeds were germinated in vertical plates, transferred after 2 d at 4 °C to the growth room, and covered with aluminum foil for an additional 5 d. Four days after the aluminum foil was removed (9 d in total), LRs were counted using a streoscope. For AR counting, plants were grown for 9 d after the dark period (14 d in total). (A–C) Representative plant images after 14 d. (D, E) LRs and ARs were counted after 9 d and 14 d, respectively. Error bars show the SEs; n, number of plants for each line. The statistical evaluation was done using Scheffe analysis that implied the significant difference between 3KO plants on one hand, and Columbia or 3KOR plants on the other (marked by double asterisks; P<0.01).
