香蕉枯萎病致病分子机理与防治研究进展

摘要

Fusarium wilt of banana is considered as one of the most destructive worldwide diseases of banana, caused by Fusarium oxysporum f. sp. Cubense, a kind of soil epiphyte, and is badly endangering the production of banana, which arises extensive attentions and researches, but the understanding of the molecular pathogenic mechanism is not still clear. This review focused on the infection process of Fusarium oxysporum f. sp. cubenes, the components of pathotoxin, pathogenic genes of Fusarium oxysporum, the disease resistance of banana, and control of Fusarium wilt of banana. These attempted to make a systematical view on pathogenesis of fusarium wilt of banana, which would be helpful for the set of new prevention method.%香蕉枯萎病是一种由尖孢镰刀菌古巴专化型引起的土传毁灭性病害,一直严重危害世界香蕉生产,从而引起广泛关注和深入研究,但其致病机理到目前还不清楚.本文综述了香蕉枯萎病菌侵染寄主的过程、致病毒素的成分分析、致病相关基因、香蕉的抗病性和枯萎病防治等方面的研究进展,为全面、深入地揭示香蕉枯萎病致病的分子机理和开展新的防治途径提供研究方向和思路上的启发.
