A chimeric gene comprising a coding sequence operatively linked to a plant-expressible promoter, the latter being a heterologous regulatory element for the coding sequence, characterized in that the coding sequence comprises a nucleic acid sequence encoding an HPPD protein that It comprises the amino acid sequence of SEQ ID No. 4 from amino acid position 2 to amino acid position 382 or an HPPD protein with at least one sequence identity of at least 80% with the amino acid sequence of SEQ ID NO. 4 from amino acid position 2 to amino acid position 382, presenting the properties of catalyzing the conversion of para-hydroxyphenylpyruvate into homogentisate, and being less sensitive to an herbicide inhibitor of HPPD than the endogenous HPPD of the host plant.
