New research looks to combat SCN through neuroscience
Lurking in more than 99% of soybean fields across the Midwest is a worm capable of feeding on and damaging entire crops. Millions of dollars have been spent trying to combat these destructive pests through the development of resistant soybean plants, but after decades of successful use, those solutions have begun to fail. Once again, soybean production is in trouble, and researchers are being forced back to the drawing board, but this time they are looking to attack the nematode from within.
Variable weather makes weeds harder to whack
URBANA, Ill. – From flooded spring fields to summer hailstorms and drought, farmers are well aware the weather is changing. It often means spring planting can’t happen on time or has to happen twice to make up for catastrophic losses of young seedlings.
Global analysis suggests COVID-19 is seasonal
URBANA, Ill. – With cities around the globe locking down yet again amid soaring COVID-19 numbers, could seasonality be partially to blame? New research from the University of Illinois says yes.
In a paper published in Evolutionary Bioinformatics, Illinois researchers show COVID-19 cases and mortality rates, among other epidemiological metrics, are significantly correlated with temperature and latitude across 221 countries.
Energy sorghum may combine best of annual, perennial bioenergy crops
URBANA, Ill. – Large perennial grasses like miscanthus are a primary target for use as bioenergy crops because of their sustainability advantages, but they take several years to establish and aren’t ideal for crop rotation. Maize and other annual crops are easier to manage with traditional farming, but they are tougher on the environment.
Energy sorghum, a hefty annual plant with the ecological benefits of a perennial, may combine the best of both crops.
What happens when the coronavirus mutates?
New mutations to the coronavirus that causes COVID-19 are emerging, including a more-infectious variant first found in the United Kingdom, even as vaccines containing bits of viral genetic material are beginning distribution. Gustavo Caetano-Anollés, a professor in the Department of Crop Sciences and a member of the Carl R.
Male weeds may hold key to their own demise
URBANA, Ill. – Scientists are getting closer to finding the genes for maleness in waterhemp and Palmer amaranth, two of the most troublesome agricultural weeds in the U.S.
Finding the genes could enable new “genetic control” methods for the weeds, which, in many places, no longer respond to herbicides.
Drones and AI detect soybean maturity with high accuracy
URBANA, Ill. – Walking rows of soybeans in the mid-summer heat is an exhausting but essential chore in breeding new cultivars. Researchers brave the heat daily during crucial parts of the growing season to look for plants showing desirable traits, such as early pod maturity. But without a way to automate detection of these traits, breeders can’t test as many plots as they’d like in a given year, elongating the time it takes to bring new cultivars to market.
Illinois-led research aims to clean agricultural drainage water
URBANA, Ill. – The Natural Resources Conservation Service (NRCS), part of the U.S. Department of Agriculture, has awarded $1.12 million to support University of Illinois-led research to clean agricultural drainage water through saturated buffers and denitrifying bioreactors. The investment, part of NRCS’s Conservation Innovation Grant (CIG) program, was matched by numerous stakeholder partners in Illinois, Iowa, and Minnesota, for a total of nearly $2.25 million.
Cassava may benefit from atmospheric change more than other crops
CHAMPAIGN, Ill. — Carbon dioxide fuels photosynthesis, the process by which plants generate their food in the form of carbohydrates. The atmosphere’s carbon dioxide levels are rapidly increasing, but there is uncertainty about whether plants can turn these extra resources into higher yields while retaining nutritional quality.
Corn and other crops are not adapted to benefit from elevated carbon dioxide levels
URBANA, Ill. -- The U.S. backs out of the Paris climate agreement even as carbon dioxide (CO2) levels continue to rise. Through photosynthesis, plants are able to turn CO2 into yield. Logic tells us that more CO2 should boost crop production, but a new review from the University of Illinois shows that some crops, including corn, are adapted to a pre-industrial environment and cannot distribute their resources effectively to take advantage of extra CO2.
