Comparison of Soil Higher Fungal Communities between Dead and LivingAbies koreanain Mt. Halla, the Republic of Korea

摘要

To improve our understanding of the relationship between soil higher fungi (belonging to Ascomycota and Basidiomycota) andAbies koreana, we surveyedA. koreanasoil fungal communities in a forest in Mt. Halla, Jeju Island, Korea by next-generation sequencing (Illumina Miseq). To confirm the soil higher fungal communities, we collected two types of soils from a defined plot: soils with dead (AKDTs) and livingA. koreana(AKLTs), respectively. Soil fungi were classified into 2 phyla, 19 classes, 64 orders, 133 families, 195 genera, and 229 OTUs (895,705 sequence reads). Nonmetric multidimensional scaling (NMDS) showed significantly different soil higher fungal communities between AKDTs and AKLTs (p < .05). In addition, the saprophyte composition was significantly affected byA. koreanastatus (p < .05). The proportion of the mycorrhizalClavulinaspp. was different between soils with AKDTs and AKLTs, suggesting thatClavulinaspp. may be a crucial soil fungal species influencingA. koreana. This study will lead to a better understanding of the ecological status ofA. koreanain Mt. Halla. In addition, this study could be useful for the conservation and management ofA. koreanahabitats.
