Interaction of just 2 genes governs coloration patterns in mice
Date:8/13/2007

CAMBRIDGE, Mass. -- Biologists at Harvard University and the University of California, San Diego, have found that a simple interaction between just two genes determines the patterns of fur coloration that camouflage mice against their background, protecting them from many predators. The work, published this week in the journal PLoS Biology, marks one of the few instances in which specific genetic changes have been linked to an organism's ability to survive in the wild.

"Our work shows how changes in just a few genes can greatly alter an organism's appearance," says Hopi E. Hoekstra, John L. Loeb Associate Professor of the Natural Sciences in Harvard's Faculty of Arts and Sciences. "It also illuminates the pathway by which these two genes interact to produce distinctive coloration. There's reason to believe this simple pathway may be evolutionarily conserved across mammals that display lighter bellies and darker backs, from mice to tuxedo cats to German Shepherds."

Hoekstra and co-authors Cynthia C. Steiner at UCSD and Jesse Weber at Harvard studied Peromyscus, a mouse that is the most widespread mammal in North America. Within the last several thousand years, these mice have migrated from mainland Florida to barrier islands and dunes along the Atlantic and Gulf coasts, where they now live on white sand beaches. In the process, the beach mice's coats have become markedly lighter than that of their mainland brethren.

"In nature there is a tremendous amount of variation in color patterns among organisms, ranging from leopard spots to zebra stripes, that help individuals survive," says Steiner, a postdoctoral researcher in UCSD's Division of Biological Sciences. "However, we know surprisingly little about how these adaptive color patterns are generated. In this paper, we identify the genetic changes producing a simple color pattern that helps camouflage mice inhabiting the sandy dunes of Florida's Gulf and Atlantic coasts. These 'beach mi
