| Outline of Final Research Achievements |
To visualize nitrogen and carbon cycling potential in the soils of farmland and forest, we used 18 farmland samples collected at Yamagata, Tokyo, and Kumamoto and also 40 planted and natural forest soil samples collected at various locations from Hokkaido to Okinawa in this study. By analyzing the metagenomic sequences generated from each soil sample using MAPLE system, we calculated completion ratio of the 766 functional modules registered in the KEGG database, and the abundance of each module and composition of taxonomical composition of the microbial community based on the ribosomal proteins. In addition, we performed the statistical analyses with non-metric multidimensional scaling method based on the functional module abundance and taxonomical composition. As a result, paddy and field soils were clearly separated with a significant p-value and the patterns of functional abundance and taxonomic composition of planted and natural forest were found to correlate to the soil pH value.
