Phenotype characterization of efo/FveUFO1. A, A wild-type shoot showing the primary flower (bending) and the secondary and tertiary flowers. B, An efo mutant flower showing many more flowers originating from what would be a single flower in wild type. C, An efo flower showing elongated internodes between whorls of sepals/leaves and axillary flower buds. D, The back of a wild-type flower showing five bracts in the outermost whorl and five sepals in alternating positions. E, The back of a mutant flower showing many whorls of leaves (L) or leaf-like organs, in the axils of which many young flower buds reside (arrows). F, Wild-type flower. G, A wild-type petal (top) and three wild-type stamens (bottom). H, An efo flower showing a larger central receptacle giving rise to many more carpels/ovaries than in the wild-type in F. The central receptacle is flanked by a whorl of stamens, then a whorl of petals, then a whorl of sepal-like organs. This central flower is on top of additional whorls of stamens, petals, and sepals. I, Mosaic stamen/petal organs are often seen in the mutant flowers. J, Mosaic sepal/petal organs are often seen in the mutant flowers.
