Characteristics of the tomato mutant Altered in all reproductive traits (Art). a Art leaves show an irregular arrangement and size of leaflets. b Expression of the GUS reporter carried by the enhancer trap in the leaf vascular bundles. c The first inflorescences are of enormous size and combine reproductive and vegetative traits. d-e Most of the Art fruits are totally aberrant. f-h The abnormal fruits do not arise from the ovary, but develop in an ectopic way in the union zone of the pedicel and the ovary base. Note the intense GUS reporter expression in the zone where the ectopic development of most of the fruits occurs. i When Art plants are kept in the greenhouse for more than 8 months, some small and seedless fruits that do not reach maturity develop. j In the fruits that develop in old plants, GUS expression is very intense in all tissues. Bar (a-e and i-j) = 1 cm; Bar (f-h) = 1 mm
