Dodder uses the flowering signal of its host plant to flower

Researchers from the Chinese Academy of Sciences and the Max Planck Institute for Chemical Ecology have investigated how the parasitic dodder Cuscuta australis controls flower formation. They showed that the parasite eavesdrops on the flowering signals of its host plants in order to activate its own flowering machinery. By synchronizing flowering with its host plant, the parasite makes sure that it can grow on its host long enough to produce the optimal amount of seeds.
