Genetics

Few pests eat away at farm profitability as much as soybean cyst nematode (SCN). Causing at least $1.5 billion in yield losses annually, it’s soybean’s single biggest threat. Unfortunately, soybean’s most effective tool, genetic resistance, is starting to fail. 

Chronic Wasting Disease, a prion protein disease that is fatal in elk, deer, and other cervids, has spread rapidly across the United States since it was first identified in 1967. CWD has now reached Idaho near the Oregon border, causing concern for the Columbian white-tailed deer, a rare subspecies found only in two regions in Oregon.

Thanks to research breakthroughs by CABBI’s internationally known miscanthus experts and geneticists, this unique plant is poised to be a game-changer on the bioenergy front — and beyond.

Genes are the building blocks of life, and the genetic code provides the instructions for the complex processes that make organisms function. But how and why did it come to be the way it is? A recent study from the University of Illinois Urbana-Champaign sheds new light on the origin and evolution of the genetic code, providing valuable insights for genetic engineering and bioinformatics.

Scientists from the University of Illinois Urbana-Champaign have developed a method to isolate genes from amounts of microbial DNA so tiny that it would take 20,000 samples to weigh as much as a single grain of sugar. In a new paper, the researchers used the method to discover previously unknown antibiotic resistance genes in bacterial DNA isolated from fish habitats at Chicago’s Shedd Aquarium and separate samples of human stool.

Small grains researcher Juan David Arbelaez-Velez knows the secret to making perfect rice — and it’s not about how you cook it. Arbelaez and his team are investigating the genetic blueprint that determines different grain attributes such as appearance, cooking time, and texture. Their paper, published in The Plant Genome, offers a strategy that will help breeders improve grain quality holistically, while cutting costs and saving time.

How do wildlife researchers know when an endangered population is sick? They can detect infectious microbes in animal waste, but the presence of a microbe doesn’t always equate to impactful symptomatic infections. In a new study, University of Illinois Urbana-Champaign researchers used advanced molecular tools to survey the health status of endangered Indiana bats, identifying microbiome changes resulting from parasitic infections.

Weeds like Palmer amaranth make farming harder and less profitable, and available herbicides are becoming less effective. For scientists to find solutions, they first need to know their enemy. A new study from the University of Illinois Urbana-Champaign and collaborating institutions reveals complete chromosome-level genomes for Palmer and two other Amaranthus species, smooth and redroot pigweed.

The National Science Foundation (NSF) has funded University of Illinois Urbana-Champaign research that aims to connect the dots between quantitative and molecular genetics and improve crop breeding.

When giant ragweed takes hold in a crop field, the towering weed reduces yield and sends plumes of its famously allergy-inducing pollen into the air. There are few tools available to thwart the menace, especially for farmers growing non-GMO soybeans. Now, some Wisconsin farmers are left with even fewer options.
