A key challenge in biology is to understand how diversity in organismal form is generated. While key regulators that shape the body plans of model organisms have been identified, less is known about how the balance of conservation versus divergence of relevant developmental pathways influences cell growth to generate morphological diversity. To help address this issue, we developed the Arabidopsis thaliana relative Cardamine hirsuta into a versatile system for studying morphological evolution. We use a combination of genetics, advanced imaging and computational modelling to understand the mechanisms through which leaf morphology evolved in these species, resulting in simple leaves in A. thaliana and complex leaves with leaflets in C. hirsuta. This presentation will describe progress on identifying such mechanisms and in conceptualizing how they regulate the number, position and timing of leaflet production.
