Transformation of Herbicide Resistance Genes

By 葉大振, 李國權, 曾夢蛟, Ta-Jen Yeh, Kuo-Chuan Lee and Menq-Jiau Tseng


殺草劑在現代農業中扮演相當重要的角色,除了提供經濟地控制雜草及提供作物生產之效益之外;有很多殺草劑同時具有高效力殺草的特性,及低動物毒性,且在環境中迅速分解。但是些殺草劑通常缺乏選擇性。利用遺傳工程的技術,在作物導入抗殺草劑基因,使其抗耐殺草劑,不受殺草劑危害,將可突破這種殺草劑使用的限制。因此抗殺草劑基因的研究,將使殺草劑的應用更具效益;對於殺草劑作用的機制,也將有更近一層的認識。在抗殺草劑作物的轉殖研究中,除了許多基因轉移成功的例子之外;更近一步發展出,利用殺草劑最為篩選藥劑,適合用於單、雙子葉植物在基因轉移時的篩選。Herbicides play an important role in modern agriculture. It provides economic weed control and increaes the efficiency of crop production. A number of new herbicides combine high efficiency with lower toxicity to animals and rapid degradation after application. However, they often lack selectivity which limits to their use in growing crops. Advance in genetic engineering promise to expand the possible application of broad-spectrum herbicides by introducing genes for resistance into susceptible crops. Herbicides-resistant trait expressed in transgenic plants has been provided as a delectable marker for plant transformation
