Disclosed is a method for selecting a transformant cell with good efficiency using a mutant ALS gene which is excellent in specificity to a PC herbicide. The method comprises the steps of transforming a host cell with a recombinant vector having a target gene and a gene encoding a mutant acetolactate synthase which has a mutation by the substitution of glycine corresponding to the residue at position 95 in the amino acid sequence for rice wild-type acetolactate synthase by alanine to produce a transformant cell and culturing the transformant cell in the presence of a pyrimidinylcarboxy herbicide, the gene encoding the mutant acetolactate synthase being used as a selection marker.

La présente invention concerne un procédé de sélection d~une cellule de transformation efficace à l~aide d~un gène mutant d~ALS qui présente d~excellentes propriétés en matière de spécificité pour un herbicide PC. Le procédé comprend les étapes de transformation d~une cellule hôte avec un vecteur de recombinaison présentant un gène cible et un gène encodant une acétolactate synthase mutante présentant une mutation par la substitution de la glycine, correspondant au résidu en position 95 dans la séquence d~acides aminés pour l~acétolactate synthase de type sauvage du riz, par un groupe alanine en vue de produire une cellule de transformation et de cultiver la cellule de transformation en présence d~une herbicide de pyrimidinylcarboxy, le gène encodant l~acétolactate synthase mutant étant utilisé comme un marqueur de sélection.
