First Strawberry Genome Sequence Promises Better Berries

11.01.2011
An international team of researchers, including several from the University of New Hampshire, have completed the first DNA sequence of any strawberry plant, giving breeders much-needed tools to create tastier, healthier strawberries.

Tom Davis, professor of biological sciences at UNH, and postdoctoral researcher Bo Liu were significant contributors to the genome sequence of the woodland strawberry, which was published last month in the journal Nature Genetics.

“We now have a resource for everybody who’s interested in strawberry genetics. We can answer questions that before would have been impossible to address,” says Davis, who has been working on the strawberry genome project since 2006 as part of the international Strawberry Genome Sequencing Consortium.

For instance, says Davis, breeders can now look at the DNA “fingerprint” of strawberry plants to more easily breed those with enhanced flavor, aroma, or antioxidant properties. Or they could breed more disease-resistant berries, decreasing the significant amount of spraying that cultivated strawberries currently need to thrive and thus enhancing the berry’s healthful qualities.

Further, the woodland strawberry is a member of the Rosaceae family, which includes apples, peaches, cherries, raspberries, and almonds, all economically important and popular crops; researchers say the DNA sequence of the strawberry genome will inform the breeding of these other fruits. “We can now begin to understand how evolution works at the level of the genome on this family of plants we all enjoy,” says Davis.

The genome sequencing effort, led by researchers at the University of Florida and Virginia Tech, found that the woodland strawberry -- Fragaria vesca – has240 million base pairs of DNA (compared to 3 billion for humans), making it one of the smallest genomes of economically significant plants. The consortium focused first on sequencing the wild woodland strawberry because its cultivated cousins, all hybrids, are far more complex.

Building upon prior publications in which he described a one percent genomic sampling of a native New Hampshire wild strawberry, Davis played multiple roles in genome project planning, data interpretation, and manuscript preparation. Liu’s unique contribution to this effort was to independently document the locations of specific sequences called ribosomal gene clusters on the chromosomes themselves, using an advanced microscopic technique known as fluorescent in situ hybridization.

The Nature Genetics paper, “The genome of the woodland strawberry,” is available here: http://strawberrygenes.unh.edu/Published.740%5B1%5D.pdf. By fortuitous coincidence, the complete genomic sequence of another delectable plant species, Theobroma cacao (chocolate), was published in the same journal issue. More information on strawberry genome work at UNH is at strawberrygenes.unh.edu. The UNH component of this work was supported, in part, by the New Hampshire Agricultural Experiment Station and by a grant from the U.S. Department of Agriculture (National Research Initiative) Plant Genome program.

The University of New Hampshire, founded in 1866, is a world-class public research university with the feel of a New England liberal arts college. A land, sea, and space-grant university, UNH is the state's flagship public institution, enrolling 12,200 undergraduate and 2,300 graduate students.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
