The wheat genome is five times larger than the human genome and originates from three highly similar sub-genomes. Mapping the genome in 2018 opened opportunities to identify and understand wheat gene characteristics, such as yield. | Robin Booker photo

Researchers find gene that improves wheat yield

Scientists were surprised to discover that the gene that increased yields also resulted in higher protein levels

Researchers have identified a genetic driver in wheat that improves wheat yield and can increase protein content by as much as 25 percent. The discovery of a gene that controls these two desirable factors has the potential to expand wheat breeding and generate new varieties. “Our research aims to understand the genes that control ear […] Read more

Stewart’s wilt, also known as P. stewartii, makes corn serve it dinner before attacking it.  |  J.K. Pataky/University of Illinois at Urbana-Champaign photo

Research shows a bacterial feeding frenzy in corn crops

Bacteria force plants to produce a feast of nutrients that support pathogens before they kill corn cells

Corn crops face a variety of bacterial threats but one species of bacteria, Pantoea stewartii, which causes Stewart’s wilt, takes that threat further than most. In a gorging frenzy, they feed themselves by forcing the plant to produce a feast of nutrients that keep the pathogens alive before they kill the corn cells. In addition, […] Read more

The disease is caused by a protein in the fungus Sclerotinia sclerotiorum. Recently, scientists with the United States Department of Agriculture’s Agricultural Research Service and Washington State University identified the protein as SsPINE1. Knowledge of the protein offers opportunities for researchers to develop more precise measures to combat the disease. | Screencap via cropwatch.unl.edu

Research reveals white mould vulnerabilities

White mould stem rot is a destructive crop disease that is widespread in Canada. It infects more than 600 plant species including crops such as potatoes, soybeans, sunflowers, peas, lentils, canola as well as other broadleaf crops. It can cause 50 percent yield loss in some cases. The disease is caused by a protein in […] Read more

Researchers breed varroa resistant honeybees

The bees were selectively bred to strengthen a trait in which they expell infested larvae from the hive, killing larvae and mite

Many beekeepers face a challenging spring as they cope with massive honeybee losses. Those range from 40 percent across the Prairies to 60 percent in Quebec. Some honey producers have lost as much as 90 percent of their bees due in large part to the parasitic mite varroa destructor mite. In addition, some farmers are […] Read more

Meadows need full legion of bees to stay healthy

Researchers find that the more plant species there are in a meadow, the more bee species are required for pollination

Think of bees and most people think of honeybees and bumblebees as the striped, fuzzy familiar insects that pollinate flowers and crops. However, Canada has some 800 native species of bees while the United States has more than 4,000 native bee species. Many live solitary lives rather than in hives and don’t make honey. But […] Read more


The presence of wildlife species in an area is often a strong indicator of a healthy ecosystem and the study, which was conducted between 2015 and 2018, sought to understand the link between farm size and populations of wild birds in surrounding areas. | File photo

Farm size influences avian diversity, says researchers

A study shows that research is showing that bird populations are adjusting to larger farm sizes with fewer species

Large-scale farming can have detrimental effects on wild species. A recent study led by the University of British Columbia in collaboration with Vrije Universiteit Amsterdam, the University of Göttingen, and the University of California, Santa Barbara, looked at the environmental impact of farm size on bird species. The research showed that increased farm size results […] Read more

New research has shed light on how wheat protects itself from disease, showing that the plants use a type of chemical warfare when under attack from pathogens.  |  File photo

Chemical defence compounds found in wheat

Wheat is one of the oldest and most important cereals and is grown on more land area worldwide than any other food crop, supplying one fifth of the calories consumed by the global population. Yet wheat suffers major yield losses due to attacks by pests and pathogens. In 2010 the wheat genome was decoded, and […] Read more

For years, scientists have questioned what controls the ability of plants to avoid self-fertilization, also known as self-incompatibility (SI). Now, scientists at the University of Birmingham in the United Kingdom have  identified a gene that controls SI. | Getty Images

Scientists find gene that controls plants’ self-fertilization

Many crops rely on pollination to flourish, while many others are able to self-fertilize. For years, scientists have questioned what controls the ability of plants to avoid self-fertilization, also known as self-incompatibility (SI). Now, scientists at the University of Birmingham in the United Kingdom have identified a gene that controls SI. They worked with the […] Read more


Researchers from Cornell University say their Rheolex system sets the stage for evaluating semen fertility and quality and opens up IVF options.  |  Jeannette Greaves photo

Researchers develop easy test to check fertility in bulls

A natural process called rheotaxis is used to measure sperm’s ability to swim upstream in the reproductive tract of cows

Testing the fertility and virility of breeding bulls can be expensive and time consuming. Scientists at Cornell University in New York have developed a quick test to check if bulls have the right stuff. The system is called the Rheolex method and it draws on the natural process called rheotaxis, in which the bull’s sperm […] Read more

Tobacco was planted in a field with heaters set to keep their plants 5C warmer than the ambient temperature. The engineered plants produced 26 percent more biomass than the wild-type plants exposed to the same temperatures. The engineered plants also had 15 percent less yield loss under the higher temperatures than non-engineered plants. This gave the researchers insight into how to improve the yields of food crops under the same stress.  |  R.I.P.E./University of Illinois photo

Research lets plants beat the heat

Genetic modifications create synthetic pathways that helps plants fix more CO2 and less of the more yield costly O2

As global warming increasingly threatens crop production, scientists at the University of Illinois and the United States Department of Agriculture, Agricultural Research Service, have found a way to safeguard plants against the dangers of heat. Researchers have improved the efficiency of a plant’s photorespiration through bypassing a photosynthetic shortcoming in a particular enzyme found in […] Read more
