'Self-activation' is part of the success strategy of parasitic weeds
Parasitic weeds extract water and nutrients from their host plants. But what makes these parasites so successful? A study led by Prof Susann Wicke from the Institute for Evolution and Biodiversity at the University of Münster and published in Science Advances has shown that certain parasitic plants activate their feeding organs (haustoria) independently of the host plant. This strategy increases their ability to successfully infest the host.
