(Phys.org) -- New research at the U.S. Department of Agriculture (USDA) confirms that rising levels of atmospheric carbon dioxide facilitate the flow of genes from wild or weedy rice plants to domesticated rice varieties. As a result, domesticated plants could take on undesirable weedy characteristics that may interfere with future rice production.
