Abstract

The parasitic weed, broomrape, attaches to the root of such vegetable crops as tomato, potato, beans, and sunflowers. With no need for leaves of its own, it produces only a floral shoot above ground. Meanwhile, its host is barely able to survive, much less be productive. Now, the defense mechanism of another pest - the fly - may provide a weapon against parasitic weeds.
