| 摘 要： | 软腐病是世界范围内多种温带、亚热带植物包括很多经济上重要的农作物所发生的一种严重的细菌性病害。对于软腐病原菌的入侵，植物体内存在一系列防御机制。围绕软腐果胶杆菌（Pectobacterium sp.）侵染植物诱导产生的多种防御反应，包括氧化应激反应和SA、JA/ET、ABA和蛋白激酶介导的信号传导反应以及铁蛋白等参与的防御反应从分子水平进行了综述，探讨了目前研究中存在的问题，并对今后的工作进行了展望。

| Abstract: | Soft rot is one of the most serious worldwide bacterial diseases occurred in various important cash crops and in subtropical and temperate regions. Plant has developed a series of defense mechanisms to deal with soft rot pathogen invasion. This paper reviewed the progress made in studying plant defense mechanisms including activation of oxidative burst, salicylic acid (SA) and jasmonic acid (JA)/ethylene (ET), abscisic acid (ABA) and protein kinase mediated signaling pathways, as well as responses related with ferritin induced by Pectobacterium infection. Besides, this paper discussed the existing problems in current research and also prospected the future works. |
