Aster yellows is a chronic, systemic plant disease caused by several bacteria called phytoplasma. [1] The aster yellows phytoplasma (AYP) affects 300 species in 38 families of broad-leaf herbaceous plants, primarily in the aster family, as well as important cereal crops such as wheat and barley.
Genetically modified crops are under development that include resistance to HPPD inhibitors. [1] There is a pharmaceutical drug on the market, nitisinone, that was originally under development as an herbicide as a member of this class and is used to treat an orphan disease, type I tyrosinemia.
