It is easy to overlook this fact because they have become discretely embedded into our everyday lives. Plants provide us with food, medicines, and raw materials used by our industries. In spite of their importance, very few of us could name more than a tiny fraction of the plants that surround us.
True, most would have little difficulty in distinguishing between a buttercup from a dandelion (provided both are in flower) but only a hand full of experts could identify all 1600 native plants in the UK, and nobody is able to name all of the 250,000 or so plant species recorded world-wide.
Accurate plant identification on a large scale is nevertheless vital if we are to protect the most biodiverse regions of the world. Equally, plant identification based on DNA could help in the search for new sources of pharmaceutical drugs, check ingredients in food and industrial products or provide a new source of forensics information for criminal investigations.
In a step towards addressing these needs, a consortium of scientists from the United Kingdom, the USA, Sweden and Syria have collaborated in the search for one or more short pieces of DNA code that could eventually be used in an automated fashion to reliably identify almost all land plant species.
This study, recently published in the Botanical Journal of the Linnean Society, has provided a short-list of six gene regions that are present across almost all land plants, suitable for use on processed food products and sufficiently variable in their code to allow separation of closely related species. The next step is to test these regions (and a small number of others identified previously) against a very large number of plants from throughout the world.

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.
