Abstract
The present invention relates to nucleic acid sequences encoding a hydroxyphenylpyruvate dioxygenase (EC 1.13.11.27, abbreviated herein as HPPD) obtained from bacteria belonging to the subfamily Synechococcoideae, as well as the proteins encoded thereby, and to a chimeric gene which comprises such nucleic acid sequence, and to the use of such nucleic acid sequences, proteins or chimeric genes for obtaining plants which are tolerant to HPPD inhibitor herbicides.
Claims11
A method for controlling weeds in an area or a field which contains a plant or a seed, which method comprises applying, to the area or the field, a dose of an HPPD inhibitor herbicide which is toxic for said weeds, without significantly affecting the seed or plant, wherein the plant or the seed comprises a chimeric gene comprising a coding sequence operably linked to a plant-expressible promoter, the coding sequence comprises a nucleic acid sequence which encodes a Synechococcussp. hydroxyphenylpyruvate dioxygenase (HPPD) protein according to SEQ ID No. 4 from amino acid position 2 to amino acid position 350.
A method for obtaining oil or meal comprising growing a plant comprising a chimeric gene comprising a coding sequence operably linked to a plant-expressible promoter, the coding sequence comprises a nucleic acid sequence which encodes a Synechococcus sp. hydroxyphenylpyruvate dioxygenase (HPPD) protein according to SEQ ID No. 4 from amino acid position 2 to amino acid position 350, treating the plant with an HPPD inhibitor herbicide, harvesting grains from the plant and milling the grains to make meal, and optionally, extracting oil from the grains.
