Outline of Final Research Achievements

We investigated the cytoplasmic structures of bathyal benthic foraminifera, particularly focusing on vacuoles and surrounding ultrastructure. Two deep-infaunal species, which thrive below oxygen penetration depths, have unique cytoplasmic structures, while shallow infaunal species represent similar structures. The unique structures may have some links with their adaptative ecology in dysoxic environments, and further researches are ongoing in terms of functional and genetic traits.

Academic Significance and Societal Importance of the Research Achievements

本研究を通じ、単細胞ながら多室にわかれ、大きな細胞サイズを持つ有孔虫の細胞形態、そして細胞小器官の組成、微生物共生の有無などが、種によって非常に多様であることを明らかにした。これら細胞形質や細胞小器官の多様性が、世界中の多様な海洋環境での繁栄に貢献していると考えられる。また、この現象の背景を解明することは、細胞の大型化、多細胞化の進化過程を考えるうえでも興味深い知見を与えてくれるはずである。
