Auxin hypersensitivity of the different AtNUP62 genotypes. a Growth on vertical plates (9 day-old plants) on different concentrations of 2,4-D. b Primary root growth measurements on plantlets grown on agar MS/2 medium containing different concentrations of 2,4-D (two experiments). Data are means ± SE. c Bright field images (left panels) and corresponding fluorescence images (right panels) in wild-type control plant (placed on the left) and a 35S::AtNUP62-GFP plantlet, on MS/2 and 2,4-D-containing medium. Seedlings of comparable root size have been chosen. d GUS activity under the control of DR5 auxin-responsive promoter in wild-type and atnup62 mutant genetic background. Left, 11 day-old plantlets, right, 2.5 day-old seedlings
