Abstract

Flower development in angiosperms is controlled in part by floral homeotic genes, many of which are members of the plant MADS-box regulatory gene family. The evolutionary history of these developmental genes was reconstructed using 74 loci from 15 dicot, three monocot, and one conifer species. Molecular clock estimates suggest that the different floral homeotic gene lineages began to diverge from one another about 450-500 mya, around the time of the origin of land plants themselves.
