Exogenous application of auxin largely rescues the primary root growth inhibition phenotype of OE-ABI4 under ABA treatment. A, Primary root phenotype of WT and OE-ABI4 lines on 1/2 MS medium with or without ABA (30 μM) or NAA (1-Naphthylacetic acid, 1 nM) treatment. The 4-day-old seedlings on 1/2 MS medium were transferred to the medium with or without ABA or NAA, and the seedlings were harvested 1.5 days after transfer. Bar = 10 mm. B, The quantitative analysis of the primary root length for (A). The asterisks indicate the significant differences at the **P < 0.01 level by Student’s t test analysis. The values are means ± se, one experiment at least three repeats, and in one repeat, n >30 per genotype. C, The ratio of OE-ABI4:WT under each treatment in (B). Calculated as the average value in (B).
