Bayer CropScience AG owns U.S. Patent No. 6,153,401, which claims a genetically modified plant that incorporates a tfdA gene.1 Because of the product of this gene, the plant can resist a weed herbicide, 2,4-dichlorophenoxyacetic acid (2,4-D).2 The biological action associated with the tfdA gene is degradation of 2,4-D into 2,4-dichlorophenol (2,4-DCP) by an enzyme encoded by the tfdA gene.3 This enzyme was mistakenly known as a “monooxygenase” among the scientific community when Bayer was developing the invention.4

声明构建无法挽救以科学上有争议的生物机制声明的改良基因发明：来自拜耳作物科学公司诉陶氏农业科学有限责任公司的教训，728 F.3d 1324（联邦巡回法院，2013 年）

Bayer CropScience AG 拥有美国专利第 6,153,401 号，该专利要求保护一种掺入 tfdA 基因的转基因植物。1 由于该基因的产物，该植物可以抵抗杂草除草剂 2,4-二氯苯氧乙酸 (2,4- D).2 与 tfdA 基因相关的生物学作用是通过 tfdA 基因编码的酶将 2,4-D 降解为 2,4-二氯苯酚 (2,4-DCP)。3 这种酶被错误地称为当拜耳开发这项发明时，科学界中的“单加氧酶”。 4
