URBANA, Ill. – The Soybean Innovation Lab (SIL) developed a new Guide to African Soybean Seedborne Diseases and Pests for use by African seed companies, seed multipliers, research institutions, and soybean processors, whose operations demand high-quality seed. Identifying the causes of decreased seed health, which translates to poor germination, low yields, and decreased profitability, is key to building a successful soybean industry in Africa.

URBANA, Ill. – As climate change becomes increasingly difficult to ignore, scientists are working to diversify and improve alternatives to fossil-fuel-based energy. Renewable bioenergy crops, such as the perennial grass Miscanthus, show promise for cellulosic ethanol production and other uses, but current hybrids are limited by environmental conditions and susceptibility to pests and diseases.

URBANA, Ill. – Five University of Illinois faculty members received major awards at the American Society of Agricultural and Biological Engineers (ASABE) 2020 annual international meeting. The virtual event took place July 13 to 15. Illinois recipients include Paul Davidson, Vijay Singh, Richard Cooke, and Prasanta Kalita, Department of Agricultural and Biological Engineering (ABE) in the College of Agricultural, Consumer and Environmental Sciences (ACES) and The Grainger College of Engineering, and Laura Christianson, Department of Crop Sciences, College of ACES.

URBANA, Ill. – Genetically speaking, the loaf of bread you stress-baked during the COVID-19 shutdown is more complex than you think. Wheat’s 16 billion genes, organized in not one but three semi-independent genomes, can overlap or substitute for one another, making things extremely tricky for geneticists trying to enhance desirable traits in the world’s most widely grown crop.

CHAMPAIGN, Ill. — Researchers often study the genomes of individual organisms to try to tease out the relationship between genes and behavior. A new study of Africanized honey bees reveals, however, that the genetic inheritance of individual bees has little influence on their propensity for aggression. Instead, the genomic traits of the hive as a whole are strongly associated with how fiercely its soldiers attack.

CHAMPAIGN, Ill. — The crops we grow in the field often form dense canopies with many overlapping leaves, such that young “sun leaves” at the top of the canopy are exposed to full sunlight with older “shade leaves” at the bottom. In order to maximize photosynthesis, resource-use efficiency, and yield, sun leaves typically maximize photosynthetic efficiency at high light, while shade leaves maximize efficiency at low light. 

URBANA, Ill. – Like antibiotic-resistant bacteria, some herbicide-resistant weeds can’t be killed by available chemicals. The problem affects more than just the errant weed in our driveways; herbicide-resistant weeds threaten our food supply, stealing resources and outcompeting the crops that make up our breakfast cereal and feed the nation’s livestock.

The weed that represents the biggest threat to Midwestern corn and soybean production, waterhemp, has outsmarted almost every kind of herbicide on the market today.

URBANA, Ill. – Soil microbes are living, working barometers of soil health. They are responsible for turning atmospheric nitrogen into forms plants can use, and for releasing nitrogen back into the air. Farm management decisions undoubtedly affect these microscopic workhorses, but, until now, scientists didn’t have a full picture of how crop rotation and tillage influence the soil microbiome.

CHAMPAIGN, Ill. —  Lisa Ainsworth, a research plant physiologist with the USDA Agricultural Research Service and adjunct professor of plant biology and crop sciences at the University of Illinois, has been elected to the National Academy of Sciences — largely considered one of the highest honors that a scientist can receive.

URBANA, Ill. ­– Crop scientists are the original social distancers, muses Allen Parrish, director of the Crop Sciences Research and Education Center at the University of Illinois.

“Planting season is always a demanding time of the year,” he says. “We obviously have restricted working conditions with the social distancing because of coronavirus, but for the most part that’s the nature of our work­. One person on the ground getting things ready; one person in a sprayer or planter. Those are single-operator activities, so the current conditions don’t critically hinder us.
