Photoreceptor differentiation

Vertebrate vision is mediated by the function of rod and cone photoreceptors, and each species generates and maintains ratios of rods to cones, and of specific cone subtypes. We are using the zebrafish embryo as a model system for probing the mechanisms that regulate the determination and differentiation of the different photoreceptor types.
