Abstract

To improve our understanding of the relationship between soil higher fungi (belonging to Ascomycota and Basidiomycota) and Abies koreana, we surveyed A. koreana soil 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 living A. 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 by A. koreana status (p < .05). The proportion of the mycorrhizal Clavulina spp. was different between soils with AKDTs and AKLTs, suggesting that Clavulina spp. may be a crucial soil fungal species influencing A. koreana. This study will lead to a better understanding of the ecological status of A. koreana in Mt. Halla. In addition, this study could be useful for the conservation and management of A. koreana habitats.

韩国汉拿山死冷杉和活冷杉土壤高等真菌群落比较

摘要

为了提高我们对土壤高等真菌(属于子囊菌门和担子菌门)与韩国冷杉之间关系的理解,我们通过下一代测序(Illumina Miseq)调查了韩国济州岛汉拿山森林中的A. koreana土壤真菌群落). 为了确认土壤中的高等真菌群落,我们从指定的地块收集了两种类型的土壤:分别是死土壤 (AKDTs) 和活的A. koreana (AKLTs)。土壤真菌分为 2 门、19 纲、64 目、133 科、195 属和 229 个 OTU(895,705 个序列读数)。非度量多维尺度 (NMDS) 显示 AKDT 和 AKLT 之间存在显着不同的土壤高等真菌群落 ( p < .05)。此外,腐生菌的组成受A. koreana状态的显着影响 ( p  < .05)。菌根Clavulina spp的比例。具有 AKDT 和 AKLT 的土壤之间存在差异,表明Clavulina spp。可能是影响A. koreana 的重要土壤真菌种类。这项研究将有助于更好地了解汉拿山A. koreana的生态状况。此外,这项研究可能对A. koreana栖息地的保护和管理有用。
