Vascular cambium is a lateral meristem that produces xylem (wood) and phloem. We are using Arabidopsis thaliana root as a model to study vascular cambium development. Despite its small size and short life span, Arabidopsis undergoes substantial secondary growth and its cambium produces the same main xylem and phloem tissue types than the tree species. In our studies we are using an integrated approach of genetic, molecular, live imaging and mathematical modelling methods to elucidate the cellular dynamics of this lateral meristem. The long-term goal is to define the key regulatory factors, and the mechanism by which they control cambial activity.
