Discovery and characterization of ocular regulatory elements through evolutionary analysis

Project Summary Eye development is governed by complicated networks of gene regulatory elements, but the field has not yet characterized or even identified most of the regulatory sequences involved. This project will use new comparative genomics approaches to reveal hundreds of regulatory regions in the genome crucial to eye development and function. The project first aims to precisely identify chromosomal regions that are conserved in sighted species’ genomes but lost or deteriorating in six blind species with regressed eye structures. Those blind species are 3 unrelated species with the common name “mole”, 2 unrelated “mole- rats”, and a blind river dolphin. This aim will be achieved…
