Agricultural breeders have long observed that when plants or animals from different strains are interbred, the offspring tend to be stronger, healthier or generally more fit than either of their parents, although no one knew why this occurred. Now plant geneticists investigating the maize (corn) genome at Rutgers Waksman Institute of Microbiology have discovered a possible explanation for this phenomenon, known as heterosis or hybrid vigor.
The Rutgers findings, presented by research associate Huihua Fu and Professor Hugo K. Dooner in the June 11 edition of the Proceedings of the National Academy of Sciences, have important implications for the understanding of plant genetics as well as applications for improving agriculture.
"A clearer understanding of the basis of heterosis could help us develop new, more productive lines of corn or other plants," said Dooner.

After first reporting the existence of quantum knots, Aalto University & Amherst College researchers now report how the knots behave
A quantum gas can be tied into knots using magnetic fields. Our researchers were the first to produce these knots as part of a collaboration between Aalto...
Researchers have succeeded in creating an efficient quantum-mechanical light-matter interface using a microscopic cavity. Within this cavity, a single photon is emitted and absorbed up to 10 times by an artificial atom. This opens up new prospects for quantum technology, report physicists at the University of Basel and Ruhr-University Bochum in the journal Nature.
Quantum physics describes photons as light particles. Achieving an interaction between a single photon and a single atom is a huge challenge due to the tiny...
A very special kind of light is emitted by tungsten diselenide layers. The reason for this has been unclear. Now an explanation has been found at TU Wien (Vienna)
It is an exotic phenomenon that nobody was able to explain for years: when energy is supplied to a thin layer of the material tungsten diselenide, it begins to...
Researchers at Ludwig-Maximilians-Universitaet (LMU) in Munich have explored the initial consequences of the interaction of light with molecules on the surface of nanoscopic aerosols.
The nanocosmos is constantly in motion. All natural processes are ultimately determined by the interplay between radiation and matter. Light strikes particles...
Particles that are mere nanometers in size are at the forefront of scientific research today. They come in many different shapes: rods, spheres, cubes, vesicles, S-shaped worms and even donut-like rings. What makes them worthy of scientific study is that, being so tiny, they exhibit quantum mechanical properties not possible with larger objects.
Researchers at the Center for Nanoscale Materials (CNM), a U.S. Department of Energy (DOE) Office of Science User Facility located at DOE's Argonne National...
