PHB Promotes GAI Stabilization
(A–C) Root meristems of GAI-GFP (A); phb-1d, GAI-GFP (B); and PAC-treated (50 μM; 24 h) GAI-GFP (C) at 5 dpg. Scale bars, 50 μm; white arrowheads, MC.
(D) Histogram reporting the percentage of MC formation in WT; phb-1d, gai-t6; and phb-1d, gai-t6. Student’s t test. Different letters show statistical significance.
n = 20, N = 3. Error bars: SD; p < 0.005; ANOVA. See also Figure S2.
