URBANA, Ill. – Representing some of the most troublesome agricultural weeds, waterhemp, smooth pigweed, and Palmer amaranth impact crop production systems across the U.S. and elsewhere with ripple effects felt by economies worldwide. In a landmark study, scientists have published the most comprehensive genome information to date for all three species, marking a new era of scientific discovery toward potential solutions.   

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.

URBANA, Ill. – A team including scientists from the University of Illinois has identified the ways in which glyphosate-resistant waterhemp has emerged in corn and soybean fields in southwestern Ontario.

URBANA, Ill. – Bacterial leaf streak, a foliar disease in corn, has only been in the United States for a handful of years, but Tiffany Jamann says it’s a major problem in the Western Corn Belt.

URBANA, Ill. – Waterhemp and Palmer amaranth, two aggressive weeds that threaten the food supply in North America, are increasingly hard to kill with commercially available herbicides. A novel approach known as genetic control could one day reduce the need for these chemicals. Now, scientists are one step closer.

URBANA, Ill. – A corn gene identified from a 118-year-old experiment at the University of Illinois could boost yields of today’s elite hybrids with no added inputs. The gene, identified in a recent Plant Biotechnology Journal study, controls a critical piece of senescence, or seasonal die-back, in corn. When the gene is turned off, field-grown elite hybrids yielded 4.6 bushels more per acre on average than standard plants.

URBANA, Ill. – Seedstock breeders and commercial cow-calf producers interested in purchasing a total-performance-tested bull will want to attend the 2019 Illinois Performance Tested Bull Sale. The sale will be the leadoff event of the Illinois Beef Expo.
