soil fungi

Little is known about the spatial and temporal patterns of the diversity of tropical fungi, including mycorrhizal fungi which form symbiotic relationships with plant roots. Both arbuscular mycorrhizal fungi (AMF) in the class Glomeromycetes and ectomycorrhizal fungi (EMF) in Bacidiomycetes and Ascomycetes assist plants to acquire soil nutrients such as phosphorus in exchange of the phothosynthates allocated from host plants. Thus mycorrhizal fungi can strongly affect nutrient and carbon cycles in terrestrial ecosystems. However, our understanding of the relationships between plants and soil fungi in Southeast Asia remains very poor. The aim of this study was to elucidate mycorrhizal fungi in the soil of seasonal tropical forests at Sakaerat Biological Reserve in Southeast Thailand, to explore the effects of forest types (dry deciduous vs. dry evergreen forests) and season (rainy vs. dry seasons). We analyzed the community composition of soil fungi based on a massively parallel amplicon pyrosequencing and found 818 operational taxonomic units from the samples collected in the rainy season. The dry deciduous forest exhibited significantly more diverse fungal community than the dry evergreen forest, even though tree species is higher in dry evergreen forest. These results represent the first report of the diversity patterns of soil fungal communities from a South East Asian forest.
