International Team Sequences Rainbow Trout Genome

April 30, 2014

An international team of researchers has mapped the genome of the rainbow trout, a versatile salmonid whose genetic history provides a glimpse into how vertebrates evolve. Led by Yann Guiguen of the French National Institute for Agricultural Research, the 30-person team focused on how the rainbow trout's genes evolved since a rare genome doubling event occurred approximately 100 million years ago. The researchers also found the fish retained its original or nearly original genes involved in embryonic development and the development of connections between nerve cells. The timing associated with these changes suggests gene evolution after an event such as this is, a much slower process than previously thought.
