由禾顶囊壳小麦变种(Gaeumannomyces graminis var.tritici)侵染引起的小麦全蚀病是小麦上一种重要的根部病害,广泛分布于世界各小麦种植区。近年来,小麦全蚀病在黄淮冬麦区发生呈上升趋势。选育和种植抗病品种是解决小麦全蚀病危害的根本途径,抗病基因研究是抗病育种的基础性工作。随着目前克隆基因数量的日益增加,利用已知抗病基因的保守序列或根据已有抗病基因的序列信息克隆抗病基因已经成为抗病及相关基因克隆
Total eclipse of wheat (EHT) caused by Gaeumannomyces graminis var. Tritici infection is an important root disease in wheat and widely distributed in various wheat growing areas around the world. In recent years, the total eclipse of wheat in Huanghuai winter wheat area is on the rise. Breeding and planting resistant varieties is the fundamental way to solve the damage caused by total erasing of wheat. Research on disease-resistance genes is the basic work of disease-resistant breeding. With the increasing number of cloned genes, the cloning of disease-resistance genes by using the conserved sequence of the known resistance genes or the sequence information of the existing resistance genes has become a disease-resistant and related gene clone
