dc.description.abstractIt has been proposed that the diversification of the MADS-box gene family of transcription factors has played a major role in the radiation of land plants. This suggestion is based on the critical roles that these genes play in plant development and the apparent coincidence of key duplication events with major radiations, such as the establishment of the B and C lineages concurrent with the evolution of the seed plants. On a more recent scale, it is also possible that subsequent duplication events have contributed to later morphological diversifications. In order to investigate this possibility, we are studying the evolution of homologs of the petal and stamen identity genes <i>APETALA3</i> (<i>AP3</i>) and <i>PISTILLATA</i> (<i>PI</i>) in the Ranunculaceae. In this family, the <i>AP3</i> and <i>PI</i> lineages have undergone many duplication events at every phylogenetic level. Early duplications gave rise to three paralogous <i>AP3</i> lineages, which are found throughout the family. In contrast, numerous duplications have occurred relatively recently in the <i>PI</i> lineage. We outline a hypothesis that these duplications have played a role in the evolution of the unique types of petaloid organs in the Ranunculaceae and present preliminary expression data supporting such a scenario.en
