How do you lose a trait?

This is interesting. Apparantly, the Danforth Plant Science Center has had some issues lately with misplacing their plant traits, so to speak. Seven years ago, researchers developed a line of cassava, an African shrub with a starchy, potato-like root, with resistance to a particular plant virus. Cassava farming generates one of the highest calorie-per-acre yield in world agriculture, so it's a major staple in many locales. Obviously, there's a big benefit to reducing the plant's sensitivity to disease.
Only problem is, this week they gave the plants a check-up and (oops!) they'd lost their resistance. The Danforth Center pulled together a war room and today announced that their new genes had been deactivated by the plants DNA regulation circuitry.
Well, i suppose it was fun while it lasted.
