Photograph of two Arabidopsis plants that either are from a genotype deficient in DNA methylation and small interfering RNAs from transposable elements (right) or has been rescued with the introduction of short hairpin RNAs. Whereas the plant on the left has four white petals like a normal plant, the plant on the right lacks these petals.
