| 16665871 | Muhitch MJ: Acetolactate Synthase Activity in Developing Maize (Zea mays L.) Kernels. Plant Physiol. 1988 Jan;86(1):23-27. When assayed using unpurified homogenates, embryo acetolactate synthase activity appeared less sensitive to inhibition by + and by the imidazolinone herbicide imazapyr than endosperm acetolactate synthase activity. |

Plant Physiol. 1992 Dec;100(4):1909-1913. The concentrations of herbicide required to reduce in vitro acetolactate synthase (ALs) activity 50% with respect to control assays minus herbicide for biotype WLR1 was greater than those for susceptible biotype VLR1 by a factor of > 30, > 30, 7,4, and 2 for the herbicides chlorsulfuron, sulfometuron-methyl, imazapyr, imazathapyr, and imazamethabenz, respectively. |

We report the successful engineering of a mutant acetolactate synthase (ALS) gene into carrot, allowing control of broomrape already in heterozygotes of the first back-crossed generation, by imazapyr, an imidazolinone ALS inhibitor. |

Such target-site resistances have allowed foliar applications of herbicides inhibiting enol-pyruvylshikimate synthase (EPSPS) acetolactate synthase (ALS) (e.g. chlorsulfuron, imazapyr) and synthase (asulam) for Orobanche control in experimental conditions with various crops. |

The mutants used were the chlorsulfuron-resistant GH50 (csr1-1), the imazapyr-resistant GH90 (csr1-2), the triazolopyrimidine-resistant Tzp5 (csr1-3) and the multiherbicide-resistant, double mutant GM4.8 (csr1-4), derived from csr1-1 and csr1-2 by intragenic recombination (G. |

Plant Cell Physiol. 2006 Mar;47(3):372-9. Epub 2006 Jan 17. To confirm the generality of the GT system in Arabidopsis, and to characterize the EGT event in plants in detail, we converted ALS from a herbicide (imazapyr)-susceptible to a -resistant form by GT. |

Heredity. 2002 Jan;88(1):8-13. The frequency of individuals resistant to the sulfonylurea herbicide sulfometuron-methyl varied from 2.2 x 10 (-5) to 1.2 x 10 (-4) and the frequency of individuals resistant to the imidazolinone herbicide imazapyr varied from 1 x 10 (-5) to 5.8 x 10 (-5) depending on the population. |

| 16667804 | Saxena PK, King J: Lack of Cross-Resistance of Imidazolinone-Resistant Cell Lines of Datura innoxia P. Plant Physiol. 1990 Nov;94(3):1111-1115. Two cell lines of Datura innoxia resistant to two imidazolinone herbicides, imazapyr and imazaquin, were isolated from mutagenized, predominantly haploid cell suspension cultures. The variation in resistance and cross-resistance of chlorsulfuron-resistant (PK Saxena, J King [1988] Plant Physiol 86: 863-867) and imidazolinone-resistant cell lines of Datura innoxia demonstrates the possibility of separate mutations of acetolactate synthase gene resulting in specific phenotypes. |

Acetolactate synthase (ALS), the first enzyme in the biosynthetic pathway of and is inhibited by imidazolinone herbicides. To understand the molecular basis of imidazolinone resistance, we isolated the ALS gene from an imazapyr-resistant mutant GH90 of Arabidopsis thaliana. |

A biotype of Aster squamatus (Sprengel) Hieronymus with suspected resistance to the ALS-inhibiting herbicide imazapyr was detected in a chicken farm in the province of Seville, Spain, which had been treated once a year with imazapyr for 10 years. |

In vitro acetolactate synthase (ALS) activity of the R biotype was 183, 35, 130 and 31 times more resistant to imazosulfuron, bensulfuron-methyl, cyclosulfamuron and pyrazosulfuron-ethyl, respectively, than the S biotype. Accession #9 exhibited cross-resistance to other sulfonylurea herbicides, bensulfuron-methyl, cyclosulfamuron and pyrazosulfuron-ethyl, but not to the imidazolinone herbicides, imazapyr and imazaquin. |
