Outline of Final Research Achievements

Since no organisms linking prokaryotes and eukaryotes have been found, it is likely that they have already been culled in the process of evolution or live in places difficult to collect. In this research, we anticipate the possibility of the latter, find out the organisms using microorganisms collected from the deep-sea floor of the Izu-Ogasawara offshore Seamount. Through comprehensive screening by transmission electron microscopy, we found the possibility that microorganisms attached to deep sea weed beetle collected are such organisms. Furthermore, for the experimental analysis, we have developed an advanced system of the laser microdissection system (Advanced-LMD) which easily cut microscopic region of less than 1 μm in diameter. In addition, we constructed a system to recover a large number of samples at once by the capillary phenomenon of the glass capillary.
