A new study by a team of plant biologists from the National University of Singapore found that some plants may selectively kill part of their roots to survive under cold weather conditions.
Microbes are widely used to break down plant biomass into sugars, which can be used as sustainable building blocks for novel biocompounds. Getting the right microbial community for this process is still a matter of trial and error. New insights by University of Groningen microbial ecologist Diego Javier Jiménez and colleagues could make a rational design possible. They argue this point in an opinion paper published in the journal Trends in Microbiology on June 22.
The absence of a single dominant bumblebee species from an ecosystem disrupts foraging patterns among a broad range of remaining pollinators in the system -- from other bees to butterflies, beetles and more, field experiments show.
Plant diseases pose a serious threat to global food security, especially in developing countries, where millions of people depend on consuming what they harvest. In sub-Saharan Africa, one plant disease in particular -- maize lethal necrosis -- is ravaging one of the region's preferred crops for food, feed and income. But understanding its biology in order to manage the disease is difficult because the disease arises from two viruses interacting -- which is where mathematics comes into play.
An international team of researchers has used mathematical modelling to understand new ways of combating maize lethal necrosis, an emerging disease that poses a serious threat to food security in sub-Saharan Africa.
Corn is grown not only for food, it is also an important renewable energy source. Renewable biofuels can come with hidden economic and environmental issues, and the question of whether corn is better utilized as food or as a biofuel has persisted since ethanol came into use. For the first time, researchers at the University of Illinois have quantified and compared these issues in terms of economics of the entire production system to determine if the benefits of biofuel corn outweigh the costs.
Research from the University of Illinois is helping to determine the quality of protein in wheat middlings and red dog, two coproducts of the wheat milling process that can be included in diets fed to pigs and other livestock.
In a new study from Lawson Health Research Institute (Lawson) and Western University, researchers have shown that probiotics can potentially protect honey bees from the toxic effects of pesticides.
The federal Supplemental Nutrition Assistance Program (SNAP) -- formerly known as 'food stamps' -- that helps low-income individuals and families purchase food is less likely to be used by farmworkers eligible for the benefit who are immigrants, Hispanic, male, childless or residing in California, new research from UC Davis health economists shows.
Currently, agriculture accounts for approximately 9% of total US greenhouse gas (GHG) emissions. By varying diet formulation and the associated crop production to supply the diet, farmers can affect the quantity of GHG emissions of various feeding systems. Therefore, researchers from the University of Wisconsin-Madison created a study to compare the effects of feeding strategies and the associated crop hectares on GHG emissions of Wisconsin certified organic dairy farms.
