Feedback regulation between CUC2 and auxin activity maxima via PIN1. (A–F) Confocal micrographs of DR5::GFP expression (green, arrowhead) in sixth rosette leaf 500 μm in length (A and B), fifth rosette leaf 750 μm in length (C and D), and close-up of fifth rosette leaf 750 μm in length (E and F) in wild type (A, C, and E) and cuc2-3 (B, D, and F). (G and H) Confocal micrographs of PIN1::PIN1:GFP expression (green) in close-up of fifth rosette leaf 750 μm in length in wild type (G) and cuc2-3 (H). Arrows indicate auxin convergence point. (I–L) CUC2::GUS staining in sixth rosette leaf 350 μm in length (I and K) and eighth rosette leaf 190 μm in length (J and L) following mock treatment (I and J) or 1 μM IAA treatment (K and L). (Scale bars: A–H, 25 μm; I–L, 50 μm.)
