Soybeans generally are not considered a major source of lutein; however, concentrations of the chemical suggest that it could represent a dietary lutein source in some Asian countries, where soybeans are an important food crop. Increasing the lutein level in soybeans have now become a priority for some breeding programs.
Researchers at McGill University, the Centre de Recherche sur les Grains, and Agriculture and Agri-Food Canada in Quebec have studied the impact crop management practices and cultivar selection have on lutein concentrations in soybean grown in multiple environments.
Their study was funded by research grants from the Ministère de l’Agriculture, des Pêcheries, et de l’Alimentation du Québec (MAPAQ) and the Natural Sciences and Engineering Research Council of Canada (NSERC). Results from the study are published in the May-June 2011 issue of Crop Science.
Almost all crop management practices investigated affected soybean lutein concentrations in most of the environments. The seeding date had the greatest effect on concentrations of the chemical, with differences in lutein concentration averaging 41%. Seeding rate, row spacing, and fertilization effects were moderate, never exceeding an 8% difference between treatments. Scientists were able to identify soybean genotypes with high and stable lutein concentrations.
"This suggests that the selection and development of high lutein cultivars should be possible," said Philippe Seguin, McGill University professor and author of this study. Additionally, environmental factors and crop management practices should be considered in the production and use of soybean as a lutein source.
Research is ongoing to identify the specific factors that affect soybean lutein concentration. This research will could help expand the markets for soybean producers.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
