The MADS-box floral homeotic gene lineages predate the origin of seed plants

Phylogenetic and molecular clock estimates

Research output: Contribution to journalArticle

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.
