Disclosed is a gene coding for a protein (a) or (b) showing a high level of resistance to PC herbicides or sulfonylurea herbicides. The protein (a) consists of an amino acid sequence of any one of SEQ ID NOS: 2, 4, 6 and 8, and the protein (b) consists of an amino acid sequence derived from the amino acid sequence of any one of SEQ ID NOS: 2, 4, 6 and 8 by substitution, deletion or addition of at least one or more amino acids, has resistance to a pyrimidinyl carboxy herbicide, and has acetolactate synthase activity.

Gene coding for acetolactate synthase

The present inventors successfully cloned the rice Na/Hantiporter gene. It is possible to produce salt tolerant plants by using the isolated gene, or genes with equivalent functions.

Sodium/proton antiporter gene

The present invention provides a gene encoding ALS protein which shows a extremely high level of resistance to pyrimidinyl carboxy herbicides. The gene of the present invention encodes an acetolactate synthase protein, for instance, according to SEQ ID NO:1, where the acetolactate synthase protein has resistance to a pyrimidinyl carboxy herbicide and has acetolactate synthase activity.
