  The subject invention provides novel plants that are not only resistant to 2,4-D, but also to pyridyloxyacetate herbicides. Heretofore, there was no expectation or suggestion that a plant with both of these advantageous properties could be produced by the introduction of a single gene. The subject invention also includes plants that produce one or more enzymes of the subject invention “stacked” together with one or more other herbicide resistance genes. The subject invention enables novel combinations of herbicides to be used in new ways. Furthermore, the subject invention provides novel methods of preventing the development of, and controlling, strains of weeds that are resistant to one or more herbicides such as glyphosate. The preferred enzyme and gene for use according to the subject invention are referred to herein as AAD-12 (AryloxyAlkanoate Dioxygenase). This highly novel discovery is the basis of significant herbicide tolerant crop trait and selectable marker opportunities.

  本发明提供了新的植物，不仅对2,4-D具有抗性，而且对吡啶氧乙酸类除草剂也具有抗性。迄今为止，没有预期或建议通过引入单个基因可以产生同时具有这两个优点的植物。本发明还包括将本发明的一个或多个酶“堆叠”在一起与一个或多个其他除草剂抗性基因一起产生的植物。本发明使得可以使用新的除草剂组合以新的方式。此外，本发明提供了预防和控制对一种或多种除草剂，如草甘膦具有抗性的杂草品系的新方法。根据本发明使用的首选酶和基因被称为AAD-12（芳氧烷基酸脱氧酶）。这一高度新颖的发现是显著的除草剂耐受作物性状和可选择标记机会的基础。

  Larger (C₆-C₁₂) esters of substituted 2-pyridinyloxyalkanoic acids, such as 1-methylheptyl (4-amino-3,5-dichloro-6-fluoro-2-pyridinyloxy)acetate, are prepared in high yield and purity by first preparing the methyl or ethyl ester and then transesterifying with a C₆-C₁₂ alcohol. The methyl or ethyl ester can be prepared by alkylation of an alkali metal salt of 4-amino-3,5-dichloro-6-fluoro-2-pyridinol with methyl or ethyl chloroacetate and the transesterification can be carried out in the presence of a tetraalkyl titanate catalyst.

  首先制备甲基或乙基酯，然后与 C₆-C₁₂醇进行酯交换反应，可以高产率和高纯度制备取代的 2-吡啶基烷酸的较大（C₆-C₁₂）酯，如 1-甲基庚基（4-氨基-3,5-二氯-6-氟-2-吡啶氧基）乙酸酯。甲酯或乙酯可通过 4-氨基-3,5-二氯-6-氟-2-吡啶醇的碱金属盐与氯乙酸甲酯或乙酯的烷基化反应制备，然后在四烷基钛酸酯催化剂存在下进行酯交换反应。
