University of Massachusetts Amherst researchers have discovered that the anatomical adaptation helping weedy rice varieties to proliferate is not confined only to these pest varieties.
The way we cultivate rice inadvertently selects for weedy behavior, the researchers say.
The research shows that despite 10,000 years of human cultivation, a cell tissue that allows rice plants to easily drop their seeds remains a feature in nearly all cultivated varieties.
Scientists had previously believed that cultivated rice had lost its abscission zone and that the degree of roughness at the base of a rice grain could signal if it had been present, and thus if that rice grain had shattered or not.
This also means that our understanding of the long history of humans and rice needs updating.
