Abstract
The ability to finely control the temporal aspect of biological processes is of the utmost importance for living beings, for example in signal transduction, cell cycle, and embryonic development. Both prokaryotes and eukaryotes display molecular architectures that govern peculiar temporal patterns, such as the vernalization process in plants, and the circadian rhythms in plants and cyanobacteria. The gene regulatory networks underlying such behaviors have been extensively studied, but we lack a comprehensive insight into their dynamics. Most importantly, we need to understand how to manipulate them in order to engineer programmable biological systems, such as biocatalysts, biosensors or biocomputing modules, that operate in a controlled and reliable fashion. Synthetic biology aims to fill this gap using a bottom-up approach, namely by designing and assembling function-oriented temporal circuits composed of well characterized molecular parts.
