Fig. 1. Leaf phenotypes of w, w3 and w6. (A) wild-type unipinnate compound tomato leaf. (B) w6 plants produce, from the base to the apex, less compound leaves with irregularly shaped blades, cup-shaped leaves and wire-like leaves. (C) w3 plants with less compound leaves. Often wire-like leaves produce two ectopic leaves (el) distally and a SAM (star) is formed between the junction of these two ectopic leaves. (D) Scanning electron micrograph of the ectopic meristem in C. (E) w leaves. (F) Axillary buds on w6 plants. Scale bars: (A-C,E,F) 1 cm, (D) 250 µm.
