Weedy rice has become herbicide resistant through rapid evolution

Biologists used whole-genome sequences of 48 contemporary weedy rice plants to show how herbicide resistance evolved by gene flow from crop rice. Almost all other cases of herbicide resistance in agricultural weeds result from selection of tolerant genotypes in the weed species.

Study First to Link Weed Killer Roundup® to Convulsions in Animals

A study is the first to link the use of the herbicide Roundup® to convulsions in animals. Glyphosate, the weed killer component in Roundup®, is the world’s most commonly used herbicide. Results showed that glyphosate and Roundup® increased seizure-like behavior in soil-dwelling roundworms and provides significant evidence that glyphosate targets GABA-A receptors. These communication points are essential for locomotion and are heavily involved in regulating sleep and mood in humans. What truly sets this research apart is that it was done at significantly less levels than recommended by the EPA and those used in past studies.
