Researchers of the All-Russian Scientific Research Institute of Plant Cultivation, Russian Academy of Agricultural Sciences (St. Petersburg) jointly with their colleagues from Germany and Finland have grown up new lines of Solanum cultivated plants via the somatic hybridization method – hybrids of wild species of plants of the Solanum family with cultivars of tomato and potato, that posess new useful properties.
Potato and tomato – the plants that occupy the honorary place in the menu of mankind – belong to the Solanum family. So do multiple wild species inhabiting Mexico, they are inedible, but possess the qualities interesting to selectionists, such as disease and vermin stability, salt-tolerance, psychrotolerance. However, this interest has remained theoretical up to recently: the majority of wild species was reluctant to interbreed with cultivars. Therefore, the researchers of the All-Russian Scientific Research Institute of Plant Cultivation, Russian Academy of Agricultural Sciences (St. Petersburg) jointly with their colleagues from Germany and Finland set about cultivating new Solanum species via the somatic hybridization method.
There exist different methods for introduction of required genes into the cultivated plant’s genome. Genetic engineering which is now much talked about is only one of them and far from being the most important if we recall the centuries-old history of selection. Interbreeding of species and lines, pollination of one plant by the pollen of the other are still used by selectionists. However, such interbreeding, particularly the interspecific interbreeding does not always work well. In the 70s-80s, a new method emerged that allowed to overcome the barrier of non-interbreeding: somatic hybridization.

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.
