ISU study: Aphid attacks weaken genetic defenses in soybeans, may open door for other pests
Aphids possess a unique ability to block the genetic defense response of soybeans and may open the door for other pests to do even more damage to crops, according to a recent study by researchers at Iowa State University. The paper found that aphids essentially can short-circuit the hormonal defense mechanism in soybeans meant to combat insect infestations, making it easier for other pests, such as the soybean cyst nematode, to colonize the plant as well.
Evolving microbes help Iowa State engineers turn bio-oil into advanced biofuels
A research team led by Iowa State University's Laura Jarboe is working to develop hungry, robust microbes that can ferment biofuels from the bio-oil produced by rapidly heating biomass such as corn stalks and sawdust. It's all part of Iowa State's efforts to combine two conversion paths -- thermochemical and biochemical -- to find efficient ways to produce renewable fuels and chemicals.

ISU experts see signs for optimism as harvest reaches peak in Iowa
The latest government crop yield predictions may give grain farmers cause for optimism as the harvest season reaches its crescendo in Iowa. Although slightly lower than previous projections, last week’s crop yield report from the U.S. Department of Agriculture is a far cry from the worst-case scenarios many farmers braced for earlier this summer as a withering drought took hold of much of America’s prime farmland.
