Double flowers—though beautiful—are mutants. The genetic interruption that causes that mutation previously helped scientists pinpoint the genes for normal development of flower sexual organs in Arabidopsis thaliana. Now scientists have proved the same class of genes at work in a representative of a more ancient plant lineage, offering a glimpse further back into the evolutionary development of flowers.
