Abstract

Plants harbor diverse foliar endophytic fungi (FEF). Host species is a major determinant of FEF community structure. When considering the host effect on FEF communities, however, it is often challenging to minimize the effects from the variability of other biotic and abiotic environmental factors. In this study, we focused on a bog system to study the host–FEF community relationship, where four woody plant species of almost identical size are codistributed on small hummocks. FEF community structure did significantly differ among the four host species. It was also suggested that host phylogenetic relatedness may partially explain FEF community structure. Indicator species analysis indicated that around 10 % OTUs were host-specific, and analyses using FungalTraits showed that most are plant pathogens. Overall, foliar endophytic fungi appear to be filtered by host species, but determining the ecological roles of host-specific FEF will require further study.

日本北海道独特沼泽系统叶面内生真菌群落变异的来源

植物有多种叶面内生真菌（FEF）。寄主种类是FEF群落结构的主要决定因素。然而，在考虑寄主对FEF群落的影响时，将其他生物和非生物环境因素的变异性的影响最小化往往是具有挑战性的。在本研究中，我们以一个沼泽系统为研究对象，研究了四种大小几乎相同的木本植物共同分布在小丘上的寄主- fef群落关系。4种寄主间FEF群落结构存在显著差异。宿主系统发育亲缘关系可能部分解释了FEF的群落结构。指示种分析表明，大约10%的otu是宿主特异性的，FungalTraits分析显示大多数是植物病原体。总体而言，叶面内生真菌似乎被寄主物种过滤，但确定寄主特异性FEF的生态作用将需要进一步研究。

期刊介绍： Fungal Ecology publishes investigations into all aspects of fungal ecology, including the following (not exclusive): population dynamics; adaptation; evolution; role in ecosystem functioning, nutrient cycling, decomposition, carbon allocation; ecophysiology; intra- and inter-specific mycelial interactions, fungus-plant (pathogens, mycorrhizas, lichens, endophytes), fungus-invertebrate and fungus-microbe interaction; genomics and (evolutionary) genetics; conservation and biodiversity; remote sensing; bioremediation and biodegradation; quantitative and computational aspects - modelling, indicators, complexity, informatics. The usual prerequisites for publication will be originality, clarity, and significance as relevant to a better understanding of the ecology of fungi.
