| Future Plan |
| We study the evolution of visual pigments, molecules that are key to understanding the evolution of color vision. Visual pigments are photoreceptive molecules residing in photoreceptor cells in the retina. We focus on primates and fish as study animals because of their vision diversity. We explore their genomes for the gene repertoire of visual pigments and elucidate the regulatory mechanisms of visual pigment gene expression. We also conduct field work, behavioral experiments and population genetic analyses to explore the behavioral significance of vision variations seen in New World monkeys, guppies and humans. |
