SEU has distinct genetic interactions with SHR, SCR, and SCL3. A to I, Occurrence of MC formation in roots of Col-0 (A), seu-3 (B), seu-4 (C), shr-2 (D), scr-3 (E), scl3 (F), seu-4 shr-2 (G), seu-3 scr-3 (H), and seu-3 scl3 (I) 7 d after sowing. The black outlines and white arrowheads highlight the occurrence of MC formation in the root endodermis. Scale bars = 50 μm. J and K, Expression of CYCD6;1-GFP-GUS in roots of wild-type (WT; J) and seu-3 (K) seedlings 5 d after sowing. Scale bar = 50 μm. L and M, Quantitative analysis of proportion of plants with MC formation in roots of Col-0, seu-3, seu-3 scr-3, and seu-3 scl3 seedlings 7 d after sowing. Error bars represent sd of three independent experiments (n ≥ 15). Bars with different letters are significantly different at P < 0.05, ANOVA.
