Genebanks Could Be Storing the Wrong Seeds

10.03.2011
Loss of diversity in crops has prompted many in the global agricultural community to store seeds in genebanks. The seeds can then be used for breeding new cultivars, research, or for crop variance. Crop breeds that have all but disappeared from agriculture are stored and available to the general public.

However, genebanks are modern institutions that were established after many of the old cultivars were no longer in use. The seeds stored for old cultivars were collected from numerous sources, many with little information concerning the seed. Therefore, genebanks could be storing seeds that do not genuinely represent the original cultivar.

Scientists at the Netherlands’ Center for Genetic Resources have examined the extent of the problem of non-authenticity of old cultivars in genebank collections. Using a large lettuce collection from a Dutch genebank, researchers sampled and compared DNA from seeds presumed to be identical because they bared the same cultivar name. The results of DNA testing indicated that many supposedly identical seeds did not match and levels of authenticity were lower than originally presumed, especially in older cultivars. In addition, even recently stored cultivars showed a 10% lack of authenticity.

Mark van de Wouw, the author of the study, expressed his surprise by saying, “From my experiences with other genebanks I did suspect there might be a problem with the authenticity of the seeds that was sent out to users, but I did not realize the problem to be this large. Although current procedures in the genebank avoid to a large extent that new mistakes are being made, the level of mislabeling in the past has apparently been high. It is obvious that systematized efforts need to be made to check the authenticity of the heirloom cultivars in genebank collections.”

The full study is published in the March/April 2011 issue of 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.

Im Focus: Attoseconds break into atomic interior

A newly developed laser technology has enabled physicists in the Laboratory for Attosecond Physics (jointly run by LMU Munich and the Max Planck Institute of Quantum Optics) to generate attosecond bursts of high-energy photons of unprecedented intensity. This has made it possible to observe the interaction of multiple photons in a single such pulse with electrons in the inner orbital shell of an atom.

In order to observe the ultrafast electron motion in the inner shells of atoms with short light pulses, the pulses must not only be ultrashort, but very...

Im Focus: Good vibrations feel the force

A group of researchers led by Andrea Cavalleri at the Max Planck Institute for Structure and Dynamics of Matter (MPSD) in Hamburg has demonstrated a new method enabling precise measurements of the interatomic forces that hold crystalline solids together. The paper Probing the Interatomic Potential of Solids by Strong-Field Nonlinear Phononics, published online in Nature, explains how a terahertz-frequency laser pulse can drive very large deformations of the crystal.

By measuring the highly unusual atomic trajectories under extreme electromagnetic transients, the MPSD group could reconstruct how rigid the atomic bonds are...

Im Focus: In best circles: First integrated circuit from self-assembled polymer

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.

In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...
