Abstract
A method for conferring tolerance to a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicide in a plant by expressing one or more polypeptide components of an exogenous plastoquinone-9 pathway in the plant. Nucleic acids, vectors, transgenic cells and transgenic plants useful in such a method are also disclosed.
Claims38
A method for providing to a plant increased tolerance to a 4-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor herbicide, the method comprising expressing in the plant transgenes encoding exogenous polypeptides of a cyanobacterial pathway for biosynthesis of 2-solanesyl-1,4-benzoquinol (SBQ) from endogenous chorismate, said exogenous polypeptides being the polypeptides of:
- (a) at least one cyanobacterial chorismate lyase enzyme,
- (b) at least one cyanobacterial 4-hydroxybenzoate solanesyltransferase enzyme,
- (c) at least one cyanobacterial 4-hydroxy-3-prenylbenzoate decarboxylase enzyme, and
- (d) at least one cyanobacterial solanesylphenol hydroxylase enzyme.
