Nemo's genome has been deciphered and made publicly available, helping researchers further investigate fish ecology and evolution.

The genome of the orange clownfish, immortalized in the film Finding Nemo, has been deciphered, giving researchers the most detailed information so far on reef fish genomics.

Genome - Chromosomes - Percent - Sequence - Place

"The nemo genome is composed of 24 chromosomes. We were able to sequence about 97 percent of the underlying genome sequence and then place about 98 percent of that sequence into the 24 chromosomes of the species," says computational biologist, Robert Lehman. "By any measure, that is a remarkable effort and represents a very complete genome assembly."

KAUST researchers have made their data available to the scientific community onnemogenome.orgahead of the journal publication of their results.

Orange - Clownfish - Amphiprion - Percula - Mainstay

The orange clownfish,Amphiprion percula, is a mainstay of marine biology research: it is used as a model species to answer questions related to social organization, sex change, habitat selection, predator-prey interactions and the effects of climate change and ocean acidification on fish. Availability of this genome assembly as a community resource will help researchers more deeply understand ecology and evolution of reef fish.

The team used state-of-the-art technology to sequence the orange clownfish genome. "We began by using single-molecule real-time (SMRT) sequencing, a technology that has only recently become affordable to most research groups," says co-author Damien Lightfoot, a molecular biologist on the team. Traditionally, genome sequencing is performed by reading many short stretches of a genome...
