In order to gain a quantitative understanding of the gene circuits that underlie plant development, it is critical to examine gene regulation at the single cell level. Single cell analysis has revealed that gene regulation can be surprisingly dynamic and heterogeneous, in ways that are not identified by traditional approaches that take an average from a population. In our lab we use a combination of single cell time-lapse microscopy, mathematical modelling and synthetic biology approaches to understand the design principles of dynamic gene regulation. We do this in simpler model systems such as cyanobacteria and B. subtilis, where it is possible to have precise single cell control of gene regulation, but we have also extended our approach to Arabidopsis. In Arabidopsis we are able to build on our work on simpler systems to examine the functional role of dynamic, and even stochastic, gene regulation in development.
