| Outline of Final Research Achievements |
The turtle shell is a clear example of morphological novelty, requiring the fusion of tissues not fused before, and the repositioning of body parts to completely new locations. In order to understand the evolutionary origin of the turtle, I have analyzed the regulatory genome at the specific location of the carapacial ridge (CR), the embryonic structure that ultimately controls the formation of the shell. By means of ATAC-seq, I have been able to identify about 38,000 putative regulatory elements specific to the CR that might be related to those genes controlling the carapace formation. Last, in this project we have generated custom made antibodies specifically targeting turtle proteins Lef1 and b-catenin, which will allow us to assess which of the regulatory elements identified by ATAC-seq are downstream of the Wnt pathway, the signaling pathway at the top of the network controlling the carapace development
