Gardener's Delight Offers Glimpse Into the Evolution of Flowering Plants
September 4, 2012
Double flowers--though beautiful--are mutants. The genetic interruption that causes the 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 is at work in a representative of a more ancient plant lineage, offering a glimpse further back into the evolutionary development of flowers.
