Rising CO2 Levels Affects Gene Flow in Wild and Domesticated Rice

June 1, 2012

Researchers at the USDA Agricultural Research Service confirmed that the increasing amount of carbon dioxide in the atmosphere influences the flow of genes from wild or weedy rice plants to domesticated rice varieties. This is the first study that demonstrated such occurrence and explained that the flow of genes is not uniform.

"We know that global climate change will require some farmers to revise production strategies in response to shifting weather patterns and crop demands," said ARS Administrator Edward B. Knipling. "These new findings will help plant breeders design and interpret studies on how changes in climate may affect crop response."
