Abstract

Forty-three (n = 43) endophytic fungi with different morphologic characteristics were from a medicinal plant Sceletium tortuosum, were utilized to investigate their antifungal effectiveness against pathogenic fungi. All fungal isolates exhibited antifungal activity against one or more pathogens in the dual culture test whereas only 33 fungal culture filtrates (77%) showed decent antifungal effect. Fusaria and Aspergillus were the dominate genus that displayed significant antifungal activity. Isolates GG02, GG09, ND15, and ND17 showed the broadest spectrum of antifungal activity. Furthermore, culture filtrate of Fusarium sp. DR08 exhibited a broad range of antifungal activity against all the pathogens. The results suggest endophytic fungi isolated from medicinal plant might be a source of novel bioactive molecules. To the best our knowledge, this is the first report on endophytic fungi isolated from native kougoed exhibiting antifungal activity against plant fungal pathogens.

首次报告:内生真菌的多样性具有抗真菌活性,该活性是从天然阔步羚(Setletium tortuosum L.)中分离得到的。

摘要

43种(n  = 43)具有不同形态特征的内生真菌来自药用植物苦荞麦(Sceletium tortuosum),用于研究其对病原真菌的抗真菌作用。在双重培养试验中,所有真菌分离物均表现出对一种或多种病原体的抗真菌活性,而只有33种真菌培养滤液(77%)显示出良好的抗真菌作用。镰刀曲霉是显示显着抗真菌活性的主要属。分离物GG02,GG09,ND15和ND17显示出最广泛的抗真菌活性谱。此外,镰刀菌属的培养滤液。DR08对所有病原体均表现出广泛的抗真菌活性。结果表明,从药用植物中分离出的内生真菌可能是新型生物活性分子的来源。就我们所知,这是关于从天然库戈德分离的内生真菌的首次报道,该内生真菌对植物真菌病原体表现出抗真菌活性。
