Ancient and Recent Duplications Support Functional Diversity of Daphnia Opsins.

Journal of molecular evolution - 1 Jan 2017

Brandon Christopher S, Greenwold Matthew J, Dudycha Jeffry L

Abstract excerpt

Daphnia pulex has the largest known family of opsins, genes critical for photoreception and vision in animals. This diversity may be functionally redundant, arising from recent processes, or ancient duplications may have been preserved due to distinct functions and independent contributions to fitness. We analyzed opsins in D. pulex and its distant congener Daphnia magna. We identified 48 opsins in the D. pulex...
