Interspersed CUC2 expression and auxin activity maxima are required for serration development. (A–C) Confocal micrographs showing CUC2::CUC2:VENUS (yellow, open arrowhead) and DR5::GFP (green, closed arrowhead) expression in fifth rosette leaf 130 μm in length (A), serration of fifth rosette leaf 365 μm in length (B), and serrations of fifth rosette leaf 460 μm in length (C). (D and E) Silhouette of fifth rosette leaf of control (D) and AtML1::CUC2:VENUS with smooth leaf margin (E). (F and G) Confocal micrograph of single optical section of fifth rosette leaf 370 μm in length of CUC2::CUC2:VENUS (F; yellow, open arrowhead) and AtML1::CUC2:VENUS (G; yellow, open arrowhead) expression. (H and I) Silhouette of fifth rosette leaf of mock-treated (H) and 10 μM 2,4-D-treated (I) wild-type plants. (J and K) Whole seedlings of hygromycin-resistant control (J) and AtML1::CUC2:VENUS with cup-shaped cotyledons (K). (Scale bars: A–C, F, and G, 25 μm; D, E, and H–K, 1 cm.)
