This research investigates how, where, and why certain chemicals called ‘safeners’ increase rates of herbicide detoxification in cereal crops such as grain sorghum, and how plants respond at the molecular level to safener treatment. This image illustrates a cross section of cells from a safener-treated sorghum seedling. The researchers found that safener triggers a massive expression of glutathione S-transferase (GST) proteins, which rapidly break down herbicides, mainly in the outermost cell layers.
