Abstract

The Fusarium oxysporum species complex (FOSC) contains highly specific plant pathogens and some nonpathogenic strains, such as Fo47. Our work concentrated on F. oxysporum f.sp. lini (Foln), the specific flax pathogen and the endophytic strain F. oxysporum 47 (Fo47), which is suggested to have a protective effect on flax against pathogens. We investigated the effects of apocarotenoids, including ionones and abscisic acid (ABA), on the growth and development of these fungal strains, assessing the potential fungicidal properties of these compounds and comparing the responses of the fungi. The study demonstrated that ionones significantly inhibited mycelial growth in both Foln and Fo47 strains. Our results also showed the differences in apocarotenoid's effect on studied strains in regard of sporulation, FUB genes cluster activity and fusaric acid (FA) production.
探讨类伪胡萝卜素对致病性尖孢镰刀菌的影响。lini和内生菌株Fo47
尖孢镰刀菌种复合体(Fusarium oxysporum species complex, FOSC)含有高度特异性的植物病原体和一些非致病性菌株,如Fo47。我们的研究重点是尖孢菌。亚麻特有病原菌lini (Foln)和内生菌株F. oxysporum 47 (Fo47)对亚麻具有保护作用。我们研究了类伪胡萝卜素(包括离子酮和脱落酸(ABA))对这些真菌菌株生长发育的影响,评估了这些化合物的潜在杀真菌性能,并比较了真菌的反应。研究表明,离子酮对菌株Foln和Fo47的菌丝生长均有显著抑制作用。我们的研究结果还表明,类伪胡萝卜素对所研究菌株在产孢量、FUB基因簇活性和fusaric acid (FA)产量方面的影响存在差异。
