摘　　要：小麦是世界上重要的粮食作物,但是各种病害严重威胁着小麦的产量和品质。分子生物学和植物分子病理学的发展与应用推进了植物抗病基因工程的发展。抗病基因工程与传统育种方法有机结合,是培育小麦高产、稳产、优质新品种的有效途径。本文从植物抗病反应网络上不同基因的作用方式与利用情况等角度,如抗病基因、防卫基因、信号传导基因、病程相关蛋白基因和病毒依赖性修饰基因等方面,介绍了小麦抗病基因工程的研究进展,并指出存在的问题及可能的解决策略。Wheat is one of the most important food crops in the world. The production of wheat suf- fers from various diseases. Genetic engineering is proved to be an efficient method for developing wheat germplasms with increased disease resistance. This paper reviewed the advances in wheat engineering for enhancement of disease resistance by introducing various genes in defense pathway, such as resistance genes, defense genes, signaling transduction/regulation genes, pathogenesis-related protein genes and virus-dependent modified genes, based on the results of the resistance mechanisms of other model plants. This paper also predicts the future research focuses and prospects of the genetic engineering in this field.
