球毛壳菌对植物病原真菌和根结线虫的生物防治潜力

Biocontrol potential of Chaetomium globosum against plant pathogenic fungi and root-knot nematodes:a review

球毛壳菌(Chaetomium globosum)隶属于子囊菌门、核菌纲、粪壳菌目、毛壳菌科、毛壳菌属真菌,广泛分布于空气、土壤等多种自然环境中,也是植物最常见的内生真菌之一。球毛壳菌能产生种类繁多的次级代谢产物,且其次级代谢产物具有抗真菌和杀线虫等多种生物活性,因而被制作成杀菌剂和杀线虫剂等生物农药,对植物病原真菌和根结线虫(Meloidogyne spp.)有良好的生物防治潜力。本文从球毛壳菌及其次级代谢产物抗植物病原真原菌和杀根结线虫两个方面进行综述,并探讨球毛壳菌对植物病原真菌的生防机制,为植物病原真菌及根结线虫的综合治理和新型生物农药的开发提供参考。

Chaetomium globosum is a fungal species of Ascomycota,belonging to Ascomycota,Pyrenomycetes,Sordariomycetidae,Sordariales and Chaetomium.It is widely distributed in air and soil,and it is also one of the most common endophytic fungi in plants,which can produce a wide variety of secondary metabolites.These seconday metabolites have a variety of biological activities such as antifungal and nematocidal activities to be prepared into biocides,which have a good biological control potential against plant pathogenic fungi and root knot nematode(Meloidogyne spp.).In this paper,the biocontrol mechanism of C.globosum against plant pathogenic fungi and root knot nematodes was reviewed and discussed,in order to provide some references for the comprehensive management of plant pathogenic fungi and root knot nematodes and for the development of new biopesticides.
