Pleiotropic Phenotypes of ae3-1.

(A) and (B) The 5-week-old plants of the wild type (A) and ae3-1 mutant (B). Arrowhead in (B) indicates the abnormal phyllotaxy with several cauline leaves associated together.

(C) First-pair rosette leaves of ae3-1 show different shapes: (a) a very narrow rosette leaf, (b) a lotus leaf with a long petiole, (c) a leaf bearing an ectopic structure (arrowhead) at the distal part, and (d) a needle-like leaf.

(D) ae3-1 cauline leaves often produce an ectopic leaf on their abaxial distal parts (arrowheads), and these ectopic structures occasionally develop into a leaflet (arrow and inset).

(E) Siliques of the wild type (left) and ae3-1 (right). ae3-1 siliques usually have a longer pedicel than that of the wild type.

(F) and (G) Trichomes and their support cells (arrowheads) on wild-type (F) and ae3-1 (G) leaf surfaces. ae3-1 support cells protrude from the leaf surface.

Bars = 1 cm in (A), (B), and (E), 5 mm in (C) and (D), and 50 μm in (F) and (G).
