Finding Nemo's genes

11.09.2018

An international team of researchers has mapped Nemo's genome

An international team of researchers has mapped Nemo's genome, providing the research community with an invaluable resource to decode the response of fish to environmental changes, including climate change.

In a breakthrough study led by the King Abdullah University of Science and Technology (KAUST) and the ARC Centre of Excellence for Coral Reef Studies (Coral CoE), researchers used high-tech sequencing tools to create one of the most complete genetic maps for the orange clownfish, a common reef inhabitant and star of the Disney movie, Finding Nemo.

"This genome provides an essential blueprint for understanding every aspect of the reef fish's biology," said lead author Dr Robert Lehmann of KAUST in Saudi Arabia.

"It contains 26,597 protein coding genes. And like the world's largest jigsaw puzzle, it took patience and time to assemble."

The orange clownfish, Amphiprion percula, is not only the most recognized reef fish on Earth, but also one of the most highly studied.

"This species has been central to ground-breaking research in the ecological, environmental and evolutionary aspects of reef fishes," said co-author Professor Philip Munday of Coral CoE at James Cook University in Australia.

"For example, the clownfish is a model for studying sex change in fishes. It has also helped us understand patterns of larval dispersal in reef fishes and it's the first fish species for which it was demonstrated that predator avoidance behaviour could be impaired by ocean acidification."

The team used state-of-the-art technology to sequence the clownfish's genome. Their genomic and transcriptomic data is now available via the Nemo Genome DB database at http://nemogenome.org.

"The clownfish comprises approximately 939 million nucleotides that needed to be fit together," said co-author Professor Timothy Ravasi of KAUST.

"This is an extremely valuable resource for the research community and will further establish the orange clownfish as an ideal lab subject for genetics and genomic studies."

"This is one of the most complete fish genomes ever produced," said co-author Professor David Miller of Coral CoE at James Cook University.

"Using the PacBio single molecule, real-time sequencing technology, enabled us to achieve a polished result."

The paper "Finding Nemo's Genes: A chromosome-scale reference assembly of the genome of the organge clownfish, Amhiprion percula" is published today in the journal Molecular Ecology Resources.

Im Focus: Colliding lasers double the energy of proton beams

Researchers from Sweden's Chalmers University of Technology and the University of Gothenburg present a new method which can double the energy of a proton beam produced by laser-based particle accelerators. The breakthrough could lead to more compact, cheaper equipment that could be useful for many applications, including proton therapy.

Proton therapy involves firing a beam of accelerated protons at cancerous tumours, killing them through irradiation. But the equipment needed is so large and...

Im Focus: New studies increase confidence in NASA's measure of Earth's temperature

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.

The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...

Im Focus: The geometry of an electron determined for the first time

Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.

The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

Im Focus: Quantum Cloud Computing with Self-Check

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.

Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
