Unravelling the complexity of microbial gene regulatory networks


Gene regulatory networks (GRNs) are the central control units determining the dynamics of living systems to changing environmental conditions. The recent advances in genomics and systems biology approaches have allowed the investigation of GRNs in at a resolution with no precedents. Yet, GRNs are combinatorial, where multiple signaling pathways acts together to control the large diversity of genes from each organism, and we still lack mechanistic understanding on how these complex systems at the molecular scale. This understanding is crucial for the generation of novel engineered organisms for biomedical and biotechnological application, one of the major goals of Synthetic Biology field. In this sense, in this current project will focus on the investigation of the molecular mechanism of combinatorial gene regulation in complex regulatory networks in microorganisms. In this sense, we will combine a wide number of experimental setups and computational tools to investigate the designing principles in GRNs in bacteria and yeast. Through the course of this project, we will use the knowledge generated here to construct novel expression systems aiming their use in biotechnologically relevant applications. For this, we will implement cutting edge technologies for the automatic construction synthetic GRNs, high-throughput experimental validation and the novel computational tools for data analysis. (AU)
