Article Correctness Is Author's Responsibility: Hiding in plain sight: Early rice farmers unwittingly selected for weedy imposters

Newswise imageEarly rice growers unwittingly gave barnyard grass a big hand, helping to give root to a rice imitator that is now considered one of the world's worst agricultural weeds. New research from Zhejiang University, the Chinese Academy of Sciences and Washington University in St. Louis provides genomic evidence that barnyard grass (Echinochloa crus-galli) benefited from human cultivation practices, including continuous hand weeding, as it spread from the Yangtze River region about 1,000 years ago.
