摘　　要：植物病虫草害是造成农作物减产的主要因素.使用生物技术手段培育抗病虫草害作物品种是农业发展的一个方向,将抗病虫草害基因导入到农作物的细胞中并使其在寄主细胞内稳定的遗传和表达,从而形成新的抗病虫草害品种.近年来,生物技术在病虫草害防治中的应用研究取得了一系列令人瞩目的进展,并成为应用分子生物学的研究热点.就植物抗病虫草害基因的分离、遗传转化和抗性分子机理,抗病虫草害基因工程在农业上的应用以及发展现状等国内外研究状况作一综述.The main reasons that reduced the crops yield were the plant diseases, pests and weeds. The future direction of agriculture is to breed new varieties which are resistant to a range of common diseases, pests and weeds by biotechnology. New transgenic varieties were breed by introducing extra gene resistant to diseases, pests and weeds to the cells of crops, making the extra gene inherit and express stabilized in the host cells. The paper discussed the isolation, genetic transformation and the resistant molecular mechanism of gene resistant to diseases, pests and weeds, the application and prospect of gene engineering in the control of plant disease, pest and weeds.
