Abstract

How a small number of signaling pathways can be re-used in distinct embryonic contexts to control different fates remains unclear. In this issue of Developmental Cell, Johnson and Toettcher (2019) use optogenetic approaches to explore how different dynamic ERK signaling states control specific developmental fates in the Drosophila embryo.
