But just like all wild plant species, these "crop wild relatives" (CWR) are also at risk of decline and extinction due to habitat loss, pollution, and climate change.
On Wednesday, Nov. 6, 2013, two speakers will describe the latest efforts to identify and protect the wild relatives of domesticated crop plants around the globe. The presentations are part of the American Society of Agronomy (ASA), Crop Science Society of America (CSSA), and Soil Science Society of America (SSSA) International Annual Meetings, Nov. 3-6 in Tampa, Florida.
Scientists estimate that 30 percent of plant species are now of conservation concern in just the United States alone. And crop wild relatives are possibly even more vulnerable because they've tended to be overlooked both by agricultural scientists and the conservation community.
That's now beginning to change. As more and more people recognize the importance of CWR to agriculture and food security, national and global efforts to catalog and conserve these plants are ramping up.
On Wednesday, Nov. 6, at 1:05 pm, Nora P. Castañeda of the International Center for Tropical Agriculture (CIAT) in Cali, Colombia, and the University of Birmingham, UK, will report on her team's research to gather and analyze data on the distributions of the wild relatives of 80 important food crops worldwide. After identifying hotspots of CWR diversity globally and comparing these against the CWR species already preserved in gene banks, the scientists have now generated a list of taxa in critical need of future protection.
On Wednesday, Nov. 6, at 1:20 pm: Colin Khoury, of CIAT and Wageningen University in the Netherlands, will discuss a recently completed inventory of CWR in the United States, as well as plans for protecting these plants both in gene banks and in the wild.
Although North America isn't known as a hotspot for crop plant diversity, the inventory uncovered nearly 4,600 CWR in the United States, including close relatives of globally important food crops such as sunflower, bean, sweet potato, and strawberry. In Florida, CWR include Indian pumpkin, or Okeechobee gourd, an endangered wild relative of squash that grows only on the shores of Lake Okeechobee; and Florida gama grass, a source of disease resistance and other useful traits in corn that is only found in Florida and Cuba.
Members of the media receive complimentary registration to the joint ASA, CSSA, SSSA meetings. To register or to arrange a one-on-one interview with Khoury or Castañeda, please contact Susan Fisk at the email address email@example.com

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
