Plant cells and plants are described which are tolerant to a herbicidal acetohydroxyacid synthase (AHAS) inhibitor, for example to a sulfonylurea, imidazolinone or triazolopyrimidine herbicide, wherein said tolerance is caused by an increased level of AHAS enzyme. Plant cells of the invention may be obtained by selection procedures or by genetic engineering. Further described are recombinant DNA useful in preparing said plant cells, methods of preparation of said plant cells, plants, seeds and other propagules and methods of controlling weed in a plantation consisting of plants of the invention.
本发明描述了对除草剂乙酰羟基酸合成酶(AHAS)抑制剂(例如磺酰脲类、咪唑啉酮类或三唑并嘧啶类除草剂)具有耐受性的植物细胞和植物,其中所述耐受性是由 AHAS 酶水平的增加引起的。本发明的植物细胞可通过选择程序或基因工程获得。进一步描述了用于制备所述植物细胞的重组 DNA,制备所述植物细胞、植物、种子和其它繁殖体的方法,以及在由本发明植物组成的种植园中控制杂草的方法。
