Scientists found that weedy rice has developed herbicide resistance through gene flow from crop rice, with most fields showing resistant plants within 20 years of herbicide-resistant rice cultivation. This rapid evolution is due to the close proximity of weedy and crop rice in the same fields, allowing for pollen transfer and outcrossing.
