Setaria viridis, a grass species similar to corn and sorghum, engineered to produce a natural purple pigment, anthocyanin, for use as a visual reporter on the presence of chemicals in the environment. Wild-type Setaria viridis is on the left (green plants) and the engineered plants are on the right (purple plants).
