Genetic Networks


Structure, dynamics and evolution of genetic networks

We study the functioning and the evolution of genetic networks that control gene expression in yeast. More precisely, we use transcriptomic approaches to understand the response of the genome expression to toxic environmental conditions in different yeast species. We also use gene expression imaging techniques to get real-time, quantitative information on the functioning of these networks. These global and quantitative data are then used to set up in silico models of the structure, the dynamics and the evolution of our favorite networks.

In addition to this project, we analyse the post-transcriptional networks involved in mitochondria biogenesis. About 99% of the mRNA encoding mitochondrial proteins are encoded by the nucleus. Half of them are localized and translated close to the mitochondria. We have identified several sub-classes of mitochondria-localized RNA (MLR) depending on the RNA binding proteins that recognized them. Our current project aim at eciphering spatio-temporal control allowing the biogenesis of mitochondria.
