摘　　要：火疫病由革兰氏阴性菌解淀粉欧文菌(Erwinia amylovora)引起,严重危害蔷薇科植物,是限制我国梨和苹果产业发展的重要因子。E. amylovora毒力强,寄主范围广泛,难以找到统一的根治靶标。随着耐药性菌株的出现,对该病害的控制变得更加困难。本文综述了火疫病的病害特性、发生规律、防控方法以及E. amylovora致病机制和植物抗性机制研究进展,为火疫病的深入研究和有效防治提供参考。Fire blight is an important disease caused by Gram-negative bacterium Erwinia amylovora that severely harms Rosaceae plants, and it is an important factor to restrict the development of pear and apple industries in China. Erwinia amylovora is highly virulent with a wide host range, and thus it is difficult to find a unified target for its eradication. With the emergence of drug-resistant strains, control of the disease becomes more difficult. In this paper, the disease characteristics, epidemiology, management methods and the mechanisms underlying E. amylovora pathogenicity and plant resistance were reviewed, which could provide references to further research and efficient control of fire blight.
