Molecular Mechanisms of Adaptive Evolution in Extremophiles and Their Applications

Microorganisms thrive in diverse environments on Earth, yet some regions remain uninhabitable due to extreme physical and chemical conditions, forming the "abiotic sphere." At the boundary between the biosphere and abiotic sphere・・・・・・

Lithospheric Biosphere Dynamics and Implications for Astrobiology

Over 99.97% of life on Earth depends on solar energy, including deep subsurface ecosystems sustained by photosynthetically derived compounds. However, before photosynthesis emerged・・・・・・

Serpentinization Systems and Life’s Origins

Serpentinization systems were widespread on early Earth and are considered to be linked to the origins of life and early microbial ecosystems. Our research on modern serpentinization-driven・・・・・・

Evolutionary Principles and Molecular Mechanisms in Symbiotic Microorganisms and Organelles

The evolution of organelles from symbiotic bacteria, such as mitochondria and chloroplasts, has driven major biological innovations. Recent studies reveal diverse microbial symbioses・・・・・・
