Phenotype analysis of PtAGL24 transgenic Arabidopsis. (a) Accelerated flowering of class I 35S::PtAGL24 plants (right) compared with wild-type control (left). (b) The leaf morphologies of 35S::PtAGL24 plants before inflorescences emerged. An inverted triangle indicates the juvenile to adult transition point on the basis of the abaxial trichomes appearance. (c) Wild-type Arabidopsis inflorescence. (d,e) Comparison of flowers (d) and siliques (e) from wild-type (left), 35S::PtAGL24 severe phenotype with conversion of sepals into leaf-like structures (middle) and mild phenotype similar to wild-type (right). Arrows indicate leaf-like sepals. (f) A solitary flower of 35S::PtAGL24 after fertilization. (g) Mature flowers with leaf-like sepals after anthesis in transgenic plants. (h,i) Scanning electron microscopy (SEM) pictures of inflorescence (h) and mature flower (i) of class I 35S::PtAGL24 lines. (j) SEM pictures of 35S::PtAGL24 sepal (right) with enriched trichomes (arrow) compared to wild-type sepal (left). (k–n) SEM analysis of the cell surface morphology in wild-type sepal (k) and carpel (l) and class I 35S::PtAGL24 sepal (m) and carpel (n), respectively. Scale bars: 1 mm (a–g) and 50 μm (h–n).
