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.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
