Fig. 3. Phenotypes of the ae5-1 and ae6-2 single mutants. (A,B) Primordia of the first two leaves in 3-day-old wild-type (A) and ae5-1 (B) seedlings. (C-F) Venations of the first-pair rosette leaves in wild-type Ler (C), wild-type Col-0 (D), ae5-1 (E) and ae6-2 (F). Insets in C-F show higher magnification of the vein pattern. (G-J) Transverse sections of the leaf blade in Ler (G), Col-0 (H), ae5-1 (I) and ae6-2 (J). Arrows indicate the normal abaxial intercellular spaces, while arrowheads show the ectopically positioned intercellular spaces. (K) An inflorescence of a wild-type Ler plant. (L-N) Inflorescences of ae5-1 showed various abnormalities, including disorganized inflorescences (L), abnormal phyllotaxy (M) and an ectopic leaf outgrowth that formed on distal part of the abaxial side of some cauline leaves (N, arrow). The arrowhead in M indicates two associated lateral branches; a cauline leaf was absent at the proximal end of one branch. Scale bars: 50 µm in A,B; 0.3 cm in C-F; 30 µm in G-J; 0.5 cm in K-N.
