High endogenous auxin contents led to early root development and increased numbers of roots. a Paraffin sections were prepared for control and transgenic samples collected on days 0, 4, and 5 for an analysis of adventitious root formation by histological observation. b The control and transgenic plants heterologously expressing were grown on MS medium with no exogenous growth regulators and were analyzed on days 0 and 9. c Comparison of the number of roots in the control and transgenic plants at ninth days. Data were presented as the mean ± SD (n = 15) (*P < 0.05, Student’s t test)
