Research Interests The main goal of my research for the last seven years has been to trace the evolutionary history of each of three plant developmental gene families (Class III HD-Zip, KANADI, and YABBY) and their roles in organ development and patterning in land plants. By comparing gene sequence and function in representatives of all major land plant lineages and algal relatives I am addressing questions of developmental gene evolution, organ homology, morphological evolution, and recruitment of developmental genes into new functions. The overall goal is to understand how the underlying developmental programs of land plants have changed to produce the diversity of body plans exhibited by land plants through time. I am now moving into developing a new genetic model for plants, the liverwort Marchantia polymorpha. I (along with collaborators) successfully proposed this liverwort for genomic sequencing by the U.S. DOE Joint Genome Institute and I am working with collaborators to develop standard tools for genetic manipulation. Comparison of the genetics and genomics of liverworts and other land plants will allow the assessment of ancestral developmental toolkit of land plants and the baseline for understanding the evolution of land plants, from genomes to morphological innovation.
