Agricultural parasite avoids evolutionary arms race, shuts down genes of host
A parasitic plant has found a way to circumvent an evolutionary arms race with the host plants from which it steals nutrients, allowing the parasite to thrive on a variety of agriculturally important plants. The parasite dodder, an agricultural pest found on every continent, sends genetic material into its host to shut down host defense genes.

Natural GMOs: Parasitic plants steal host DNA to siphon off needed resources
Some parasitic plants steal genetic material from their host plants and use the stolen genes to more effectively siphon off the host’s nutrients. A new study led by researchers at Penn State and Virginia Tech reveals that the parasitic plant dodder has stolen a large amount of genetic material from its hosts, including over 100 functional genes.
