Outline of Final Research Achievements

The present study was performed to evaluate the relationship between tree species, soil physico-chemical properties and microbial (i.e., fungal/bacterial) community in forest ecosystems. Soil, root, and leaf samples from tropical heath forests, tropical lowland forests and cool-temperate forests were collected. DNAs of the samples were extracted and sequenced on Illumina MiSeq platform. There were significant differences in the fungal community compositions depending on tree species and soil nutrient availability. On the other hand, spatial relationships between tree individuals and microbial community and functional relationships between trees and microbes (i.e., mutualistic or parasitic) were found to be further examined using more advanced statistical techniques.
