Like an herbivorous Count Dracula, a snakelike vine coils around its leafy victim, punctures its stem and proceeds to suck out its life juices.
The parasitic plant Cuscuta pentagona, commonly known as strangleweed or dodder, preys on many common crop plants.
Not only does the parasite siphon water and nutrients from its host, but it also exchanges genetic messages with its victim, according to a study.
The findings reveal a new way that plants communicate with each other, and the study may help scientists understand how to combat parasitic plants that destroy food crops around the world, the researchers said.
