A botanist brings a species of alfalfa from Siberia, to the United States. His hope? The plant survives, and leads to a new winter-hardy alfalfa. But what also happened during this time in the late 1800's, isn't just a story of legend and lore. The truth of the matter is creating a current revival in both interest and conservation of what's now called a crop's "wild relative."
And several researchers members of the American Society of Agronomy (ASA) and Crop Science Society of America (CSSA) say it couldn't come at a better time. The lack of attention has put crop wild relatives in a precarious position, says ASA and CSSA member Stephanie Greene. Green is a plant geneticist with the USDA-ARS in Prosser, WA and the U.S. National Plant Germplasm System, the country's primary steward of seed and other crop genetic material. Twenty percent of all wild plants are now threatened with extinction, according to recent estimates, and that's before the potential impacts of climate change are factored in. Yet, "as the world moves forward with all these initiatives to conserve biodiversity," Greene says, "it's recognized that crop wild relatives have been left behind."
Green is leading new efforts to tally crop wild relatives living in the United States, identifying which are most important to global and American agriculture, and developing a nationwide strategy for protecting the plants both in gene banks and in the wild. But conserving crop wild relatives is only the first step. The real goal is to get the diverse stock of genetic material, or germplasm, into the hands of plant breeders, especially those seeking to adapt crops to the increased drought, greater disease pressure, and erratic weather climate change is expected to bring.
But few are studying crop wild relatives more intensely or championing for protection more vigorously than Nigel Maxted, a scientist at the University of Birmingham in England. Maxted is pressing for conservation in many ways, most significantly by developing a step-by-step, standardized protocol countries can use to identify and protect the crop wild relatives within their borders. The first countries he worked with to execute a plan were Syria, Lebanon, and Jordan. Most recently, he helped Portugal, Switzerland, the U.K., and several other European nations complete conservation strategies, and he's now collaborating with several more. Two of his graduate students currently work in China and North Africa. And a former student is now assisting Greene with the U.S. strategy. Greene says, while threatened by climate change just like all wild species, these wild relatives are the same plants that could help us adapt our food systems to the new conditions. "That's why it surprises me. Why aren't these plants the poster children [for plant conservation]?" she says. "We know they have value."

The Crop Science Society of America (CSSA), founded in 1955, is an international scientific society comprised of 6,000+ members with its headquarters in Madison, WI. Members advance the discipline of crop science by acquiring and disseminating information about crop breeding and genetics; crop physiology; crop ecology, management, and quality; seed physiology, production, and technology; turfgrass science; forage and grazinglands; genomics, molecular genetics, and biotechnology; and biomedical and enhanced plants.
CSSA fosters the transfer of knowledge through an array of programs and services, including publications, meetings, career services, and science policy initiatives. For more information, visit www.crops.org

Scientists develop first tool to use machine learning methods to compute flow around interactively designable 3D objects. Tool will be presented at this year’s prestigious SIGGRAPH conference.
When engineers or designers want to test the aerodynamic properties of the newly designed shape of a car, airplane, or other object, they would normally model...
Researchers from TU Graz and their industry partners have unveiled a world first: the prototype of a robot-controlled, high-speed combined charging system (CCS) for electric vehicles that enables series charging of cars in various parking positions.
Global demand for electric vehicles is forecast to rise sharply: by 2025, the number of new vehicle registrations is expected to reach 25 million per year....
Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
Scientists have discovered that the electrical resistance of a copper-oxide compound depends on the magnetic field in a very unusual way -- a finding that could help direct the search for materials that can perfectly conduct electricity at room temperatur
What happens when really powerful magnets--capable of producing magnetic fields nearly two million times stronger than Earth's--are applied to materials that...
The quality of materials often depends on the manufacturing process. In casting and welding, for example, the rate at which melts solidify and the resulting microstructure of the alloy is important. With metallic foams as well, it depends on exactly how the foaming process takes place. To understand these processes fully requires fast sensing capability. The fastest 3D tomographic images to date have now been achieved at the BESSY II X-ray source operated by the Helmholtz-Zentrum Berlin.
Dr. Francisco Garcia-Moreno and his team have designed a turntable that rotates ultra-stably about its axis at a constant rotational speed. This really depends...
