Abstract
Promoters naturally associated with plant protoporphyrinogen oxidase (protox) coding sequences, and derivatives thereof, are provided. These promoters can be used to control the expression of an operably linked heterologous coding sequence in a plant cell. These promoters are particularly useful for expressing modified forms of herbicide target enzymes, particularly modified forms of protox, to achieve tolerance to herbicides that inhibit the corresponding unmodified enzymes. Recombinant DNA molecules and chimeric genes comprising these promoters are provided, as well as plant tissue and plants containing such chimeric genes.
