The invention discloses a paddy rice ALS (Acetolactate Synthase) mutant protein for endowing plants with resistance to herbicides. The invention further discloses a nucleic acid for coding the protein. The protein comes from a paddy rice mutant plant resisting ALS inhibitor type herbicides, and in comparison with the ALS sequence in the genome of wild paddy rice, the protein sequence of the protein is simultaneously mutated at sites Ser 627 and Gly 628 or only mutated at the site Gly 628. Plants which express the protein sequence can resist (tolerate) acetolactate synthase inhibitor type herbicides, particularly imidazolinone herbicides. The herbicide-resistant effect of the mutant mutated simultaneously at the sides Ser 627 and Gly 628 disclosed by the invention is about 30 percent higher than the herbicide-resistant capability of the mutant plant only contains mutation at the site Ser 627 or Gly 628.

This invention relates to synthetic method of 1, 3 - dimethyl - 2-imidazolidinone. The invention solves the problem in exsiting method that the reaction need 85% concentration methanoic acid as reaction medium, and the generated methanoic acid has no means of reusing. The invention takes paraformaldehyde and 2-imidazolidinone as raw material, 30% to 45%methanoic acid as reaction medium. Firstly proceed paraformaldehyde depolymerization, then add 85%or 94% methanoic acid, warm-up till circumfluence reaction for 12 hours, then gain 1, 3 - dimethyl - 2-imidazolidinone. The invention could cyclic utilize sparse methanoic acid generated from 1, 3 - dimethyl - 2-imidazolidinone synthetic reaction, thereby advance capacity utilization rate, depress manufacturing cost.

The invention discloses ALS mutant type genes. The 75th nucleotide of the ALS mutant type genes in an ALS gene sequence of rice mutates from G to nucleotide C, the 339th nucleotide of the ALS mutant type genes in the ALS gene sequence of the rice mutates from A to nucleotide C, and the 710th nucleotide of the ALS mutant type genes in the ALS gene sequence mutates from C to nucleotide T. The invention further discloses application of ALS protein coded by the ALS mutant type genes in the aspect of herbicide resistance. The protein comes from a rice mutant plant resisting ALS inhibitor herbicide. Compared with the rice wild type ALS sequence, the protein sequence of the ALS mutant type genes mutates at Gln25, Gln113 and Ala237 sites. Green plants express the protein sequence, and acetolactate synthetase resistant inhibitor herbicide, particularly imidazolone and sulfonylurea herbicide, can be resisted.
