Hidroxifenilpiruvato - dioxygenase (HPPD) Mutant DNA sequence and isolation of plants that are tolerant to herbicides based on HPPD Inhibitor, particularly tembotriona

摘要

This relates to a Nucleic Acid Sequence encoding a hidroxifenilpiruvato - dioxygenase (HPPD) Mutant, a Chimeric Gene comprising this sequence and Coding sequence and its use for plants that are resistant to herbicides based on HPPD inhibitor.Claim 1: hidroxifenilpiruvato - dioxygenase HPPD Mutant that retains its Properties to catalyze the conversion of - hidroxifenilpiruvato (PPH) and homogentisato HPPD is less sensitive than the original mutated HPPD Inhibitor,Characterized in that it contains a mutation in the amino acid Glycine of 336 position with respect to the amino acid sequence of the Pseudomonas HPPD of SEQ ID no: 2, which is selected from the following group: gly336his, gly336met, gly336phe, and gly336cys.
