Breakthrough in Molecular Genetics of Strawberry

08.12.2004


The world’s first molecular map for wild strawberry (Fragaria) constructed using transferable DNA markers has been produced by scientists at East Malling Research (EMR) in association with collaborators at the University of Reading.

This work is a breakthrough in strawberry genetic research and has already been adopted as the reference map by strawberry research groups in Spain, France and the USA. It offers the potential for further international collaboration, leading towards the integration of strawberry genetic research worldwide.

This wild strawberry map will provide a foundation for the development of a map for the genetically complex commercial strawberry (Fragaria x ananassa). This in turn will lead to greater efficiencies in strawberry breeding, ultimately achieved through the integration of molecular techniques like marker assisted selection, already successfully used in apple breeding at EMR.



Wild strawberry plants from a cross between Fragaria vesca (the woodland strawberry) and Fragaria nubicola (a wild Asian strawberry), provided a model system for studying inheritance. Apart from their simpler genetic make-up relative to cultivated strawberry and production of three generations per year, the two species also differ widely in traits potentially important for strawberry breeding e.g. fruit size, runnering, everbearing, plant architecture and aromatic composition (flavour). So far 67 DNA markers and 23 genes controlling characteristics of potential commercial importance have been located on the map, providing a framework for future work.

According to their Technical Director, Dr Alwyn Thompson, “The Worshipful Company of Fruiterers is delighted that this innovative science project which we have supported, has achieved so much for the advantage of the strawberry industry. We congratulate those involved at EMR and Reading University on producing this genetic map for Fragaria (a real breakthrough) and look forward to seeing new improved, market-leading varieties as a result of the project.”

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
