The leaf as a model to understand how boundary domains control morphogenesis.

We developed quantitative tools and modelling approaches in order to reconstruct and predict leaf development. As leaf shape is a plastic trait that can vary with environmental conditions, we believe this strategy will broaden the knowledge on plant development mechanisms and help to understand how plant adaptation and phenotypic plasticity are integrated to control leaf shape. This is particularly important in the context of climate change because agriculture will need novel varieties which responses to global warming can be predicted.

Expanding the known roles of organ boundaries during plant development.

For purpose of increasing plant performance, it is fundamental to understand whether developmental processes have been co-opted during plant evolution and domestication and whether they are conserved between species. Therefore, we explore the role of boundary domains in different developmental contexts and different species to widen our understanding of plant development.

Biological significance of boundary-controlled morphogenesis and translational research.

Patterns of hydathodes are closely linked with leaf shape. Indeed, these small water pores are often located at the tip of the serration in leaves. Hydathodes provide an entry point for various plant pathogens. We are studying their formation to provide a genetic and molecular dissection of hydathode differentiation.
