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: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
