Acetohydroxyacid synthase (AHAS) is the target enzyme of the sulfonylurea herbicides, and here we report the sequence of the gene from wild‐type and herbicide‐resistant Porphyridium sp. (Rhodophyta). The resistant mutant has a single residue substitution at a position known to confer herbicide resistance in E. coli and in plants. The rhodophyte gene is of cyanobacterial origin and distinct from the nuclear‐encoded chlorophyte gene, which may be of mitochondrial origin.
