Fig. 9From: Tobacco TTG2 regulates vegetative growth and seed production via the predominant role of ARF8 in cooperation with ARF17 and ARF19Coordinate 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)Back to article page
