Abstract
Recombinant proteins comprising on or more mitochondrial leader peptide sequences and a domain having herbicidal sulfonamide-insensitive dihydropteroate synthase activity are disclosed. Transformation of plants with nucleic acids that encode this mitochondrially-targeted recombinant protein is also provided. Such transformed plants exhibit resistance to herbicidal sulfonamides, such as asulam, and therefore may be cultivated where such herbicides are being used to control weed growth.
