Widespread fungal disease in plants can be controlled with a commercially available chemical that has been primarily used in medicine until now. In a comprehensive experiment the team has uncovered a new metabolic pathway that can be disrupted with this chemical, thus preventing many known plant fungi from invading the host plant.
Potato virus Y is the most economically important and devastating aphid-transmitted virus, affecting both tuber yield and quality. The virus is also a major cause of seed potato degeneration, which leads to regular flushing out of seed potatoes after limited field production cycles. There is no remedy for this virus and once a plant becomes infected, it stays sick for life.
