摘要:

镰刀菌引起的赤霉病和根腐病是威胁多种粮食作物安全生产的真菌病害,可引起粮食减产和谷物品质降低。田间受镰刀菌感染的谷物也会在仓储过程中造成粮食劣变和毒素污染等问题。镰刀菌通过形成侵染结构、合成细胞壁降解酶(cell wall degrading enzyme, CWDE)及毒素抵御宿主防御反应破坏植物组织完成侵染。毒素是病原真菌的重要致病因子,植物通过化学修饰和化学分隔等形式将毒素与基质结合、泵出胞外以降低毒素的植物毒性。通过杂交育种或转基因技术对解毒基因进行改良利用是防控镰刀菌病害及毒素污染的有效途径之一。综述了侵染过程中毒素等次生代谢产物在病原菌和植物互作及病害发展过程中的作用机制,以期为植物抗病育种和镰刀菌病害及毒素防控新策略的研发提供依据。

Abstract:

Scab and root rot caused by Fusarium are fungal diseases that threaten the safe production of many food crops, which can cause grain yield reduction and grain quality reduction. Fusarium infections in the field can also cause problems such as grain deterioration and toxin contamination during storage. Fusarium fulfills infection by forming infection structure, synthesizing cell wall degrading enzyme (CWDE) and toxin to resist host defense reaction and destroy plant tissue. Toxin is an important pathogenic factor of fungal pathogens. Plants bind the toxin to the matrix and pump it out of the cell to reduce the plant toxicity of the toxin through chemical modification and chemical compartmentation. The improvement and utilization of detoxification genes through cross breeding or transgenic technology is one of the effective ways to control Fusarium disease and toxin pollution. In this paper, the mechanism of secondary metabolites such as toxins in pathogen and plant interaction and disease development during infection were reviewed, which could provide a basis for plant disease resistance breeding and research, and development of new strategies for prevention and control of Fusarium disease and toxin.

Key words: Fusarium toxin, infection process, secondary metabolites, Fusarium, wheat scab
