Rising CO2 promotes weedy rice

Source: Science News25/05/2012 – There has been a lot of research, recently, showing how global change — especially warming — can alter the habitat and preferred range of marine and terrestrial species. But rising levels of greenhouse gases can also, directly, do a number on agricultural ecosystems, a new study shows. At least for U.S.-grown rice,…

USA – USDA links gene flow between weedy and domesticated rice to rising carbon dioxide levels

As a result, domesticated plants could take on undesirable weedy characteristics that may interfere with future rice production.
