Fig. 1From: Tobacco TTG2 regulates vegetative growth and seed production via the predominant role of ARF8 in cooperation with ARF17 and ARF19The expression of NtTTG2 in response to synthetic auxin NAA. Plants were treated by spraying over tops with a surfactant solution in control or with an NAA solution containing the surfactant. Relative levels of NtTTG2 expression were quantified by RT-qPCR as the transcript quantity ratios to the constitutively expressed EF1α gene used as a reference. Data shown are mean values ± standard errors from mean (SEMs) of results obtained from three experimental replicates, i.e., the number of replicates (n) = 3. Inset is Northern blot hybridization performed at 60 h after plant treatmentBack to article page
