35S:CKX2 transgenic B. napus lines have an increased root system. a Primary root length, (b) number of lateral roots, (c) lateral root density, and (d) number of adventitious roots of seedlings (6 DAG) cultured in vitro on vertical plates on half strength MS medium. Data represent mean values ± SEM (n ≥ 15). Two-tailed Student’s t-test was performed to calculate the significance of differences between transgenic lines and wild type. * p < 0.05;** p < 0.01;*** p < 0.001
