Thousands of years ago, people in South America began domesticating Solanum pimpinellifolium, a weedy plant with small, intensely flavored fruit.

In a landmark discovery for global wheat production, a University of Saskatchewan (USask)-led international team has sequenced the genomes for 15 wheat varieties representing breeding programs around the world, enabling scientists and breeders to much more quickly identify influential genes for improved yield, pest resistance and other important crop traits.

The research results, just published in Nature, provide the most comprehensive atlas of wheat genome sequences ever reported. The 10+ Genome Project collaboration involved more than 95 scientists from universities and institutes in Canada, Switzerland, Germany, Japan, the U.K., Saudi Arabia, Mexico, Israel, Australia, and the U.S.

“It’s like finding the missing pieces for your favourite puzzle that you have been working on for decades,” said project leader Curtis Pozniak, wheat breeder and director of the USask Crop Development Centre (CDC). “By having many complete gene assemblies available, we can now help solve the huge puzzle that is the massive wheat pan-genome and usher in a new era for wheat discovery and breeding.”

Researchers at North Carolina State University call for a coalition of biotech industry, government and non-government organizations, trade organizations, and academic experts to work together to provide basic information about gene-edited crops to lift the veil on how plants or plant products are modified and provide greater transparency on the presence and use of gene editing in food supplies.

Trees and other vegetation can help mitigate climate change, by taking in carbon dioxide during photosynthesis and storing it in stems, trunks, leaves and roots.

Indonesian wildfires that cause widespread air pollution and vast carbon emissions are a "fixable problem", according to the leader of a project set up to help tackle the issue.
