The primary and lateral roots of wild-type and transgenic plants. (a) Average primary root density of wild-type and transgenic plants. Wild-type and transgenic plants were grown in vitro on hormone-free medium for 2 weeks. Adventitious roots were harvested and quantitatively analysed. Bars show the means and standard errors over three events (at least 10 ramets per event). (b) The phenotype of primary and lateral roots of wild-type and transgenic plants. The length of the sides of the square grids is 0.5 inches.
