Abstract
1. Chimeric gene containing several herbicide tolerance genes, plant cell and plant which are tolerant to several herbicides. 2. The plant is tolerant to several herbicides at the same time, in particular to the inhibitors of HPPD and to those of EPSPS and/or to the dihalohydroxybenzonitriles. 3. Use for removing weeds from plants with several herbicides.
Claims21
A process for producing plants with multiple herbicide tolerance by transgenesis of the plants, comprising
- inserting into several cells respectively one of at least two basic genes, the basic genes each containing regulatory elements necessary for its transcription in plants and a coding sequence encoding an enzyme conferring on plants tolerance to a herbicide, wherein said at least two basic genes comprise first and second basic genes, said first basic gene comprising a coding sequence encoding a wild-type HPPD and said second basic gene comprising a second coding sequence encoding an enzyme conferring on plants tolerance to a herbicide;
- regenerating plants from said cells;
- and
- crossing said plants in order to obtain plants with multiple tolerance to field application rates of said herbicides.
A process for the herbicidal treatment of plants comprising applying at least two herbicides at field application rates to a plant comprising at least two basic genes comprising first and second basic genes, said first basic gene comprising regulatory elements necessary for its transcription in plants and a coding sequence encoding a wild-type HPPD, and said second basic gene comprising regulatory elements necessary for its transcription in plants and a second coding sequence encoding an enzyme conferring on plants tolerance to a herbicide.
