U of M and two Norwegian universities sign new research agreement


(11/2010) The University of Minnesota, the Norwegian University of Life Sciences and the University of Oslo renewed and strengthened their shared commitment to research on bio-based, sustainable energy and products as well as food security with the signing of a tripartite agreement in Washington, D.C. last month. The University of Oslo pledged a total of $750,000 over four years, matching gifts made by the Norwegian University of Life Sciences and the University of Minnesota in 2006 to create the Norwegian Centennial Chair and the Norwegian Centennial Graduate Fellowship. Funds support transatlantic research teams of scientists and students (undergraduate through post-doctoral fellows) from all three universities. The new, four-year agreement also marks a change in leadership.

A closer look at plant signaling networks


(09/2010) A study led by Fumiaki Katagiri and Jane Glazebrook (both PBIO) examines the negative regulatory relationships between signaling sectors in Arabidopsis immune signaling. Katagiri and his research team found that parts of the plant immune signaling network are highly interconnected and that negative regulations between signaling sectors are very common. The findings suggest that only some of the signaling sectors in the network get highly activated at a given time while the other sectors stand by to back up the primary sectors in case primary sectors are attacked by pathogens. This balances the robustness of the signaling network against pathogen attack and minimizes the negative impact of the immune response on plant fitness. Former postdoctoral student Masanao Sato and current postdoctoral student Kenichi Tsuda contributed to the study along with former CBS graduate student Lin Wang. Link to PLoS Pathogens article.

Scott Fahrenkrug featured in New Scientist


(7/7/2010) The main reason is that the genetic engineering of animals - with the exception of mice - has been a slow, tedious process needing a lot of money and not a little luck. Behind the scenes, though, a quiet revolution has been taking place. Thanks to a set of new tricks and tools, modifying animals is becoming a lot easier and more precise. That is not only going to transform research, it could also transform the meat and eggs you eat and the milk you drink. The first transgenic animals were produced by injecting DNA into eggs, implanting the eggs in animals and then waiting weeks or months to see if any offspring had incorporated the extra DNA. Often fewer than 1 in 100 had, making this a long, expensive process. "That's just really inefficient," says Scott Fahrenkrug, a geneticist at the University of Minnesota in St Paul.

Don Wyse featured in Wisconsin Ag Connection


(6/30/2010) While the U.S. job market remains in the doldrums in the wake of one of the recession, there is at least one profession bucking the trend. Job opportunities in the crop sciences are booming. Don Wyse, Ph.D., a professor of agronomy and plant genetics and director of the Center for Natural Resources and Agricultural Management at the University of Minnesota, says changing demographics also play a role.

Les Szabo featured in Scientist Live


(6/7/2010) Agricultural Research Service (ARS) scientists Yue Jin, Les Szabo and Marty Carson at the agency's Cereal Disease Laboratory at St. Paul, Minn., have solved a longstanding mystery as to why a pathogen that threatens the world's wheat supply can be so adaptable, diverse and virulent. It is because the fungus that causes the wheat disease called stripe rust may use sexual recombination to adapt to resistant varieties of wheat…The researchers began the study last year after finding infected leaves on barberry plants at two sites on the University of Minnesota campus. They initially thought the symptoms were a sign that the stem rust pathogen had overcome the resistance commonly found in U.S. varieties of barberry.

James Anderson featured in Star Tribune


(5/24/2010) The battlefields are 8,000 miles away in Africa and the Middle East. But from their bunkers of dew chambers and greenhouses in St. Paul, a strike force of University of Minnesota plant experts is devising strategies to win a high-stakes war that could prevent famine, starvation and political unrest… Eighty percent of the world's wheat and 95 percent of the Upper Midwest region's top bread-baking grain is vulnerable to the new pathogen, according to University of Minnesota wheat breeder Jim Anderson.

Chlamydomonas is a haploid, biflagellate green alga commonly used for bioenergy production and for basic research on cilia and flagella. More than 3,000 mutants are maintained by the collection, curated by Matt Laudon (PBIO), and distributed to laboratories throughout the world.


David Andow featured in Nature News


(5/13/2010) Growing cotton that has been genetically modified to poison its main pest can lead to a boom in the numbers of other insects, a ten-year study in northern China has found…The conclusion was controversial, with critics of the study focusing on the relatively small sample size and use of economic modelling. Wu's findings back up the earlier study, says David Andow, an entomologist at the University of Minnesota in St Paul. Link to Nature News article.- From CFANS News

Tilman wins prestigious science prize


(4/21/2010) Regents’ Professor David Tilman (EEB) received the 2010 Heineken Prize for Environmental Sciences from the Royal Netherlands Academy of Arts and Sciences earlier this month. Tilman was selected for his seminal findings, published in Science and Nature during the 1980s and 1990s, which showed that biodiversity is essential for stable and productive ecosystems. Tilman’s grassland experiments at Cedar Creek Ecosystem Science Reserve are among the longest running in the world, providing a rich resource for ecology research. His work at the field station is the subject of an article and a collection of short video clips recently published online by the University of Minnesota Foundation.


Study will examine sources of variation within species


(4/21/2010) Tapping into a growing interest in understanding how epigenetic variation might contribute to phenotypic variation, Nathan Springer (PBIO) is leading a study that will look at the prevalence, heritability and potential consequences of epigenetic variation in maize. The National Science Foundation is providing more than $500,000 in support of the effort. The research project will compare the DNA methylation patterns in the genome of nearly 30 different inbred lines (or breeds) of maize. DNA methylation can act as a “tag” to add additional information to DNA sequences and is one of several epigenetic marks. Epigenetics studies heritable variation that is not caused by DNA sequence changes. By adding information about the epigenome to a wealth of existing data on genetic and phenotypic information it will be possible to understand how epigenetic variation contributes to phenotypic variation within a species. The project will also study how epigenetic differences are inherited in hybrids and in recombinant inbred lines in order to assess the stability of epigenetic variation over multiple generations. The primary goal of this project is to document the role of epigenetic variation in heritable phenotypic variation within a species. Undergraduate students from the University of Minnesota and Hamline University will participate in the primary research. All data produced by this project will be made public and available to researchers studying breeding and evolution across a wide range of disciplines.


David Andow featured in MinnPost


(4/13/2010) The global uproar over fiddling with genes in food crops has quieted as millions of people ate products made from genetically engineered corn, soybeans and other plants with no apparent ill effects…David Andow is not convinced, though, that the threat is inconsequential. A University of Minnesota professor of insect ecology, Andow was one of several experts who were asked to provide “candid and critical comments” during the report’s preparation.

Judith Berman receives grant to study antifungal resistance


(3/22/2010) Distinguished McKnight University Professor Judith Berman (GCD) was awarded $422,792 from the National Institutes of Health to study the mechanisms that Candida albicans uses to generate genetic and genomic diversity, and to survive antifungal assault. Candida albicans is the most prevalent fungal pathogen of humans and a serious problem in immunocompromised patients. Resistance to antifungal drugs is of particular concern given the limited number of clinically useful antifungals. The proposed work will address basic questions about how resistance arises in response to a range of antifungal drugs with the goal of identifying potential targets for companion drugs that would extend the lifespan of the limited arsenal of available antifungals.
