Americans place high value on butterfly royalty. A recent study suggests they are willing to support monarch butterfly conservation at high levels, up to about 6 ½ billion dollars if extrapolated to all U.S. households.
If even a small percentage of the population acted upon this reported willingness, the cumulative effort would likely translate into a large, untapped potential for conservation of the iconic butterfly. (more…)
MU scientists say discovery could save farmers billions and protect the environment.
COLUMBIA, Mo. — Nitrogen fertilizer costs U.S. farmers approximately $8 billion each year, and excess fertilizer can find its way into rivers and streams, damaging the delicate water systems. Now, a discovery by a team of University of Missouri researchers could be the first step toward helping crops use less nitrogen, benefitting both farmers’ bottom lines and the environment. The journal Science published the research this month.
Gary Stacey, an investigator in the MU Bond Life Sciences Center and professor of plant sciences in the College of Agriculture, Food and Natural Resources, found that crops, such as corn, are “confused” when confronted with an invasive, but beneficial, bacteria known as rhizobia bacteria. When the bacteria interact correctly with a crop, the bacteria receive some food from the plant and, simultaneously, produce nitrogen that most plants need. In his study, Stacey found that many other crops recognize the bacteria, but do not attempt to interact closely with them. (more…)
Since its inception in 1909, University of Minnesota Extension has worked with farmers to find solutions to their biggest challenges. And, since we all eat—our biggest challenges. For the past 25 years, Extension has shared the U’s expertise by educating agriculture professionals, who in turn have the most influence on crop farmers today.
Keeping agriculture professionals on top of current research helps ensure economically and environmentally responsible cropping decisions are made throughout the state. (more…)
*Large-scale study finds soy may alleviate hot flashes in menopause*
In the most comprehensive study to date to examine the effects of soy on menopause, researchers have found that two daily servings of soy can reduce the frequency and severity of hot flashes by up to 26 percent, compared to a placebo.
The findings, published in Menopause: The Journal of the North American Menopause Association, reviewed 19 previous studies that examined more than 1,200 women. (more…)
*For ancient plants, two genes were definitely better than one*
In the wake of the disaster that killed the dinosaurs, the ancestors of today’s crop plants reinvented themselves.
They doubled their genomes, and in that single act set the stage for feeding the world 60 million years later.
In a study published in the Nov. 16 issue of the journal Nature, researchers from the University of Minnesota and other institutions recount how sequencing the genome of a model, alfalfa-like legume revealed the monumental benefits that flowed when the ancestor of legumes acquired an extra copy of every gene.

If you like tofu, tempeh, edamame or miso soup, you’re a fan of soybeans. But the significance of this legume goes far beyond a few culinary treats — soybeans rank seventh among world crops for tonnage harvested. (more…)
