Plants with increased herbicide tolerance

The present invention relates to a method of combating undesired plant growth at a Pflanzenkultivierungsort. The method comprises the steps of providing, at this location, a plant, comprising at least one nucleic acid which comprises a nucleotide sequence encoding a wild type or a mutated hydroxyphenylpyruvatedioxygenase hydroxyphenylpyruvatedioxygenase (mut-HPPD) which are resistant to a coumarone-derivative herbicide and / or is tolerant, and / or comprises a nucleotide sequence which encodes a wild-type Homogentisatsolanesyltransferase or a mutated Homogentisatsolanesyltransferase (mut-HST), which is resistant or tolerant to a coumarone-derivative herbicide, and then applying an effective amount of said herbicide on the plant cultivation site. Furthermore, the invention plants, comprising mut-HPPD, and methods for producing such plants is concerned.
