Abstract
Around 1.4 Mya, the South African daisy Gorteria diffusa radiated into several floral forms, which differ in position and morphology of black spots on their orange petals. While the petal spots of some floral forms are simple and merely serve as nectar guides to pollinating flies, other forms evolved highly complex petal spots resembling female pollinators, tricking male flies into pseudocopulation with the flower. Here, I am presenting our current knowledge on the molecular mechanisms underlying the evolution and development of the sexually deceptive G. diffusa petal spots, covering a wide range of fields including metabolomics, transcriptomics, small RNAs, comparative genomics and transposable elements.
