USDA: Rice problems linked to carbon dioxide

Research at the U.S. Department of Agriculture (USDA) links gene flow between weedy and domesticated rice to rising carbon dioxide levels.

The research 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.
