Coordinate responses of NtTTG2 and NtARF8 to auxin. WT plants were treated by spraying over tops with a surfactant solution (control) or an NAA solution containing the surfactant. Gene expression in leaves was analyzed at the indicated time points by RT-qPCR using EF1α as a reference gene. Data shown are mean values ± SEM bars (n = 3 experimental replicates)
