Parasitic plant timelapse

Scientists are looking at the relationship between a parasitic plant, dodder, and two host plants, Arabidopsis and tomatoes, as a way to study how two plants communicate. In order to suck the moisture and nutrients out of the host plants, a dodder uses an appendage called a haustorium to penetrate the plant. Researchers found that during this interaction, the two plants exchanged thousands of messanger RNA molecules, creating an open dialogue between the two plants. This exchange was previously thought impossible due to the short-lived nature of mRNA molecules.
