Abstract

Investigation of vascular plant developmental mechanisms have until recently been extremely difficult outside of the flowering plants because of a lack of appropriate tools. In the last 5 years, advances have allowed the adoption the fern Ceratopteris richardii as the first full genetic model for seedless vascular plants.  The first steps with this model have already proven useful in advancing our understanding of how important mechanisms in the flowering plants evolved, including floral development and stomata responses.

I will provide an overview of working with this new experimental model, some of the tools becoming available, and preliminary advances made in the understanding of the evolutionary origin of seeds.
