HYDROXY-PHENYL PYRUVATE DIOXYGENASE FUSED WITH A SIGNAL PEPTIDE, DNA SEQUENCE AND USE FOR OBTAINING PLANTS CONTAINING HERBICIDE-TOLERANT PLANTS

摘要

The invention concerns a nucleic acid sequence coding for a hydroxy-phenyl pyruvate-dioxygenase (HPPD) fused with a signal peptide, a chimeric gene containing said sequence as encoding sequence and its use for obtaining plants resistant to certain herbicides. The inventive fusion protein consists of a HPPD fused at its C-terminal or N-terminal end with a signal protein sequence enabling the HPPD to be directed into the cell compartments other than the cytoplasm or the plastids.
