Molecules to Morphology: Developing an Understanding of Plant Evolution Through Time

Cronk, Quentin [1].

Answered and unanswered questions in plant Evo-Devo.

The availability of numerous fully of completely sequenced angiosperm genomes has aided angiosperm-centric approaches to plant evolutionary developmental genetics and some notable progress has been made in understanding the partial history of some organ systems. However, many fundamental questions remain unresolved, particularly those that involve deeper phylogenetic nodes than those of flowering plants. For example, the root is an organ particularly well understood at the molecular level in Arabidopsis, yet fundamental questions remain unsolved concerning the molecular developmental origin of this organ. This presentation will review the state of our knowledge of some of the fundamental questions of plant organography, and will survey prospects for solving them in the light of projected complete genome sequences for two non-vascular land plants: Physcomitrella and Marchantia.
