| abstract |
The present invention provides a promoter and derivatives thereof that are naturally linked with a plant protoporpyrronogen oxidase (protox) coding sequence. These promoters can be used to regulate expression of heterologous coding sequences operably linked in plant cells. In particular, these promoters are useful for expressing modified forms of herbicide target enzymes, especially modified forms of protox, to provide resistance to herbicides that inhibit the corresponding unmodified enzyme. Not only are recombinant DNA molecules and chimeric genes comprising these promoters provided, but plant tissues and plants containing such chimeric genes are provided. |
