R. solanacearum is a soil-borne bacterium that causes
wilt disease in plants by entering their roots, then
multiplying to the point that water-transport systems are
fatally obstructed. Researchers from the University of
Wisconsin found that for defense, the plant's root cells
release DNA that form traps to kill the bacteria, but only
about 25 percent of them. Researchers hope that better
understanding of these interactions helps in breeding or
engineering disease-resistant plants.
