Abstract
The present invention relates to a nucleic acid sequence encoding a mutated hydroxyphenylpyruvatedioxygenase (HPPD) which exhibits improved tolerance to HPPD inhibitors, to a chimeric gene which comprises this sequence as the coding sequence, and to its use for isolating or obtaining plants which are resistant to certain herbicides.
