The new breed blooms longer, produces more flowers and grows under a wider range of temperatures than existing cherry blossom trees, demonstrating the power of accelerator technology in horticulture.
To create the new breed, researchers used beams of carbon ions from the RIKEN Ring Cyclotron at the RI Beam Factory to induce mutations in branches from the cherry blossom tree known as Keiou-Zakura No. 13. The branches were grafted and cultivated to create the new breed, which has been aptly named ‘Nishina Otome’.
Unlike regular cherry blossom trees, Nishina Otome does not require a period of cold weather to trigger growth. As a result, the new tree is able to bloom all year round when cultivated indoors, and during autumn and spring when grown outdoors. Given sufficient exposure to low temperatures, it produces three times more flowers than the regular varieties, and its spring bloom lasts for twice as long.
The use of heavy ion beams to generate new breeds of plants by mutagenisis, an approach to horticulture unique to Japan, is drawing attention worldwide as a powerful alternative to conventional genetic engineering that is capable of shrinking breeding times to only a few years. The second breed of cherry blossom tree to be registered by RIKEN, the Nishina Otome hints at an exciting future for accelerator-based mutation breeding, one which opens the door to the design of plant varieties better able to cope with a changing environment.

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...
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...

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.

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.
