PtGID1 overexpression in Arabidopsis plants promotes root elongation under GA application. (A) Representative 6-day-old seedling primary roots of WT, PtGID1-1, PtGID1-10, and PtGID1-12 seedlings grown on MS-agar with GA3-free, 0.2, 0.5, or 1 μM GA3. Scale bar, 1 cm (n = 36). (B) Mean lengths in cm (mean ± SD, n = 36) of WT, PtGID1-1, PtGID1-10, and PtGID1-12 seedlings grown on MS-agar with GA3-free, 0.2, 0.5, or 1 μM GA3 are presented.
