We aim to solve social issues by utilizing the technologies and resources developed in the basic theme.

Photosynthesis is a reaction that uses light energy to fix carbon dioxide and attracts significant attention as a form of renewable energy. This research aims to produce bioenergy from microalgae by enhancing their lipid metabolism system and improving their culture efficiency.

As an island nation, Japan has long utilized many fishery resources. In recent years, global demand for fishery resources has increased, and the sustainability of the fishing industry has become more critical than ever. Fish stock enhancement, famous for the release of salmon, enhances fishery resources by artificially hatching, growing, and releasing juveniles of fish. It is practiced in 40 countries around the world, including Japan. On the other hand, it is not well understood whether the released fish are only caught or contribute to further reproduction in nature. In this study, we estimate the kinship relationship between released and natural individuals to understand the fisheries resource dynamics under the fish stock enhancement program.

Human activities have a significant impact on ecosystems at various levels. Recent advances in genome analysis technology have revealed the phenomenon of "self-domestication," in which organisms with traits more likely to coexist with human activities are enhanced in each region. On the other hand, humans have long engaged in trade to link regional goods and information, contributing to habitat expansion and disturbance. The history of trade in each region is key to dealing with biological evolution at the global level. However, because many societies are illiterate, many areas remain black boxes. This study takes the approach of inferring the geographic origin of a word from its inter-language similarity and attempts to elucidate how natural resources in each region have been transmitted and utilized.
