尽管内生真菌对植物健康很重要，但目前尚不清楚这些真菌如何受到草原管理实践的影响。在这里，我们连续两年研究了施肥和割草频率对三种农业重要草种（鸭茅、红羊茅和黑麦草）地上组织内生真菌群落及其生活策略的影响。我们的结果表明，管理实践影响了植物全生物中的真菌群落，但观察到的影响因草种和采样年份而异。 2010年，球茎黑麦草内生真菌的系统发育多样性受到割草频率的显着影响，而施肥以及施肥与割草频率的相互作用分别对2010年和2011年黑麦草的群落组成产生显着影响。总而言之，我们的研究为未来研究内生真菌对管理实践的反应奠定了基础。据我们所知，这是第一项连续两年同时评估三种重要农业草种地上部分真菌内生菌群落的研究。
Despite the importance of endophytic fungi for plant health, it remains unclear how these fungi are influenced by grassland management practices. Here, we investigated the effect of fertilizer application and mowing frequency on fungal endophyte communities and their life strategies in aerial tissues of three agriculturally important grass species (Dactylis glomerata L., Festuca rubra L. and Lolium perenne L.) over two consecutive years. Our results showed that the management practices influenced fungal communities in the plant holobiont, but observed effects differed between grass species and sampling year. Phylogenetic diversity of fungal endophytes in D. glomerata was significantly affected by mowing frequency in 2010, whereas fertilizer application and the interaction of fertilization with mowing frequency had a significant impact on community composition of L. perenne in 2010 and 2011, respectively. Taken together, our research provides a basis for future studies on responses of fungal endophytes towards management practices. To the best of our knowledge, this is the first study simultaneously assessing fungal endophyte communities in aerial parts of three agriculturally important grass species over two consecutive years.
