Phenotype of eif4a1 mutant plants.

(a) Photographs of Col‐0, eif4a1 and eif4a2 plants taken at different stages of vegetative growth.

(b) Graph of mean leaf initiation rate after germination.

(c) Leaf development in Col‐0, eif4a1 and eif4a2. Images of the adaxial surface of mature fifth rosette leaves sampled 23 days after initiation.

(d) Flow cytometric analyses of mature fifth leaves sampled 23 days after initiation from Col‐0, eif4a1 and eif4a2 plants. C values are indicated on uppermost graph.

(e) Nomarski images of adaxial pavement cells of mature fifth leaves sampled 23 days after initiation from Col‐0, eif4a1 and eif4a2 plants.

(f) Root morphology in Col‐0, eif4a1 and eif4a2 seedlings grown vertically on phytagel for 9 days. The eif4a1 roots are short and lack lateral roots. Scale bars: (a) 50 mm; (c) 10 mm; (e) 50 μm; (f) 20 mm.
