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."

Crop Science is the flagship journal of the Crop Science Society of America. Original research is peer-reviewed and published in this highly cited journal. It also contains invited review and interpretation articles and perspectives that offer insight and commentary on recent advances in crop science.

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

A widely used diabetes medication combined with an antihypertensive drug specifically inhibits tumor growth – this was discovered by researchers from the University of Basel’s Biozentrum two years ago. In a follow-up study, recently published in “Cell Reports”, the scientists report that this drug cocktail induces cancer cell death by switching off their energy supply.
The widely used anti-diabetes drug metformin not only reduces blood sugar but also has an anti-cancer effect. However, the metformin dose commonly used in the...
