Transgenic OE-CYCB1;1 and OE-CDKB2;2 fully rescue the ABA-hypersensitive phenotype of OE-ABI4 with regard to primary root growth in response to ABA application. A, Primary root phenotype of Col-WT, OE-ABI4, OE-CYCB1;1, OE-CDKB2;2, OE-ABI4::OE-CYCB1;1, and OE-ABI4::OE-CDKB2;2 of seedlings grown on 1/2 MS medium with or without exposure to ABA (30 μM). The 3-day-old seedlings on 1/2 MS were transferred to the medium with or without ABA at different concentrations, and the seedlings were harvested 4 days after transfer. Seedlings on 1/2 MS medium, bar = 10 mm. Seedlings on ABA-containing medium, bar = 5 mm. B and C, The quantitative analysis of primary root length for (A) is shown. The values are means ± se. In one experiment at least three repeats, and in one repeat, >30 roots per genotype were used. The asterisks and indicate significant differences at the *P < 0.05 and **P < 0.01 levels, respectively, by Student’s t test analysis.
