Diversity of Arbuscular Mycorrhizal Fungi in Arable and Natural Soils in Korea
Eom, Ahn-Heum,Tae, Moon-Sung,Lee, Jae-Koo The Ecological Society of Korea 2004 Journal of Ecology and Environment Vol.27 No.3
The diversity of arbuscular mycorrhizal fungi (AM) was investigated in cultivated and natural fold sites or chungbuk, Korea. soils were collected from rhizosphere or Sorghum bicolor, Fagopyrum esculentum and Glycine max in cultivated sites, and of Miscanthus sinensis, Glycine soja and Lespedeza cuneata in natural sites. Total 20 species of Glomalean fungi were found in this study. Species richness, species diversity and density of AM fungi were significantly lower in the arable sites. While only AM fungal spores belong to Glomus and Acaulospora were found in arable fold sites, more diverse fungal spores including Gigasporaceae were found in natural grasslands. AM fungal spore composition did not significantly differ among crop plant species. Results suggest that the agricultural practices were significantly influenced on AM fungal community structures and mycorrhizal developments.

In this study, we isolated endophytic fungi from the conifer leaves of Pinus densiflora inhabiting Mt. Gyehwasan in Korea. We identified the isolated fungal strains based on their morphological characteristics and phylogenetic analysis using DNA sequences of the internal transcribed spacer, small subunit rDNA, large subunit rDNA, and β-tubulin region. In the process of this study, we confirmed two endophytic fungi that have not been recorded previously in Korea, Lophiostoma macrostomum and Pestalotiopsis lespedezae. In this report, we described the morphological characteristics of these fungal strains and the results of their molecular analysis.

A fungal strain was isolated from surface-sterilized roots of Rhododendron mucronulatum, a plant species belonging to the Ericaceae family, collected from Mt. Minjujisan, Korea. This fungal strain was identified as Rhizodermea veluwensis based on its morphological characteristics and based on phylogenetic analysis of its internal transcribed spacer regions and large-subunit rDNA. R. veluwensis has not been previously reported in Korea, and for the first time, we report and describe it herein.

The effects of benomyl treatment on ginsenoside and arbuscular mycorrhizal (AM) symbiosis in the roots of Panax ginseng that were collected from two sites in Korea were investigated. The ginseng roots that were treated with benomyl showed different species compositions of AM fungi colonizing the ginseng roots, compared to untreated roots. In the analysis of ginsenoside, Rc was significantly higher in benomyl untreated roots than in benomyl treated roots. The results suggest that AM fungal species composition and ginsenosides in ginseng root could be influenced by the benomyl treatment.
