Silencing SlMADS1. A, SlMADS1-silenced plants (right) show loss of apical dominance compared to control empty vector-treated plants (left). B, Flowers on control empty vector-treated plants show distinct white petals surrounded by sepals. C, Flowers on SlMADS1-silenced plants have enlarged sepals and white petals are largely absent. D, Sepals separated from inner whorls from control (left) and SlMADS1-silenced (right) flowers. E, Magnified view of inner whorls of flower dissected in D. Note reduced white petals and the presence of flower-like organs. F, Indeterminate flowers of SlMADS1-silenced plants. G, Magnified view of one of the flowers in F.
