It often requires many years of growth before a tree is ready to flower -- a delay that makes tree breeders impatient. Now, scientists at universities in Sweden and the United States have discovered genes that are responsible for initiation of flowering.
In the annual plant Arabidopsis, the first plant to have its genome sequenced, the genes Constans (CO) and Flowering Locus T (FT) induce flowering in response to day length. It turns out that Populus trees (aspens, cottonwoods, poplars), the first tree to have been sequenced, also have CO and FT genes and can be forced to flower in months, rather than years.
The discovery is being reported in Science magazine on-line (Science Express www.sciencexpress.org) on May 4, 2006, in the article, "The Conserved CO/FT Regulatory Module Controls Timing of Flowering and Seasonal Growth Cessation in Trees," by Henrik Bohlenius, Tao Huang, Laurence Charbonnel-Campaa, and Ove Nilsson of the Umea Plant Science Centre at the Swedish University of Agricultural Sciences; Amy M. Brunner of the forestry department at Virginia Tech; Stefan Jansson of the Umea Plant Science Centre at Umea University; and Steven H. Strauss of the forest science department at Oregon State University.

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.
A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
