A collaborative team of researchers from the Donald Danforth Plant Science Center, the University of Florida, Gainesville and the University of Iowa have recently developed groundbreaking tools that allow grasses -- including major grain crops like corn -- to act as living biosensors capable of detecting minute amounts of chemicals in the field.
Researchers develop tools to turn grain crops into biosensors
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.
